Migrating away from Google Maps (Wonkish)



Google has decided to begin charging for the downloading of its maps by websites although they claim that the first 100,000 downloads per month on any website are free.  helladic.info uses Google maps throughout and it is very unlikely that helladic.info would ever experience 100,000 map downloads and so this new policy would not seem to concern us.

However Google wants my payment information anyway (something it has never done before) even though helladic.info would fall into the 98% of sites that will not be affected by this policy.  The payment information is the sticking point .. along with some controversy about what 100,000 downloads really means.  I don’t wish to be exposed to this risk.

Therefore I have decided to move away from Google maps and reprogram the map pages to use Open Street Map and ESRI maps.  Indeed the first two rewrites (Place Key Report and Feature Key Report) pages are already delivered.

The new maps have more feature layers - you can try it out yourself – and they function just like the old pages did.  I don’t anticipate any impact on the way the site is used by making this change.  There is, however, significant rewriting still to do and I’m not certain that I can complete this by June 11 which is the cutoff date.

I’ll try to let you all know in advance if things change or if features are broken.  You can help me by reporting problems that you may experience during this time of refit.  

Maps on the Internet are a constantly changing and improving scene and, as I find new appropriate functionality, I will try to incorporate changes that I think useful.

Thanks for your understanding.

A minor (but frustrating) error in a Cretan gazetteer



“They said they were hair-dressers but … kind of hard to believe.”
Play It Again Sam
Woody Allen


I’m currently taking Mycenaean and Minoan sites from Crete and putting them into the Mycenaean Atlas Project database.  Today I was spotting sites in the very valuable gazetteer article:  Goodison and Guarita [2005].  Everything was going fine until I reached this:

“31. KHRONI KALYVI/ GANGALES
Location: After turning off the Ayii  Deka-Heraklion road towards Gangales,  140m on (just after the river) pass tiny chapel on left of road. 30m further on, cut across fields to the right (180m). The tomb is a few metres NW of a barn.” (1)

This tomb, possibly Early Minoan, is a circular tomb and mound of about 11 m. in diameter.  It was robbed in antiquity and, I suspect, of no really great importance or significance in itself beyond helping to fill out the picture of the extent of circular tombs in the Mesara during the EM.  Therefore the most important thing about it would be its exact position and that's what I want to establish.  There are a number of ambiguities in the directions to this tomb so I decided to take this down to the ground and provide a full description of what our authors are trying to tell us.

The main north-south road through the center of Crete runs from Heraklion to a junction with a major east-west road and very near to the town of Aghii Deka. (just a few km. further on one comes to Gortyn.)   And what our authors are saying is that if one turns towards Gangales (away from Ayii Deka to the east) then, after 140 m. one comes to a small chapel and then a road to the right which will lead to this tomb.

I tried every possible way to move 140 m. to the E from the N-S road to the main E-W road but nothing worked.  Actually 140 m. hardly gets you out of Ayii Deka.  There is a river in Ayii Deka and everything almost fit but didn’t quite.  Especially vexing was my inability to spot any tiny chapel on the edge of Ayii Deka. 

I spent a couple of hours on this and finally I just tried a guess.  Perhaps 140 was a mistype for 1400 (or something).  I started again tracing a 1400 m. route from the easiest turn-off from the N-S road to the east (another guess).  At the end of the 1400 m. trace I discovered everything together, the river, the chapel, the barn … everything.   And the ‘tiny chapel’ really was very tiny indeed; in Greece such a thing is known as a kandylakia – a roadside shrine/contribution box shaped like a full-size church.  And standing next to it was another even smaller and even more elaborate kandylakia  The people of Greece sometimes erect these kandylakia at a place where a traffic death has occurred.  They form a kind of small refuge where a person might stop and pray during the day or light a candle or give a donation.

I don’t know what these kandylakia are called in Crete but ours look like this:
 
Chapel on L, kandylakia on R.


What about the route itself?


In this aerial photo the 1400 m. route is shown in light brown.  The river which Goodison & Guarita mention is in blue.  

Since our authors don't precisely say here is a close-up of the actual exit that Goodison et al. are referring to when they reference the start of this 1400 m. route.  Here's an aerial photo of it:



The route marked in red is the main highway from Herakleion to Ayii Deka.   The outskirts of Ayii Deka are shown on the left (W).  The turn that you make is labelled 'To the Tomb'.

If you're driving towards Ayii Deka then that turn is shown in the next photo from Google Street View.






Time for a close-up of the route's end and a tentative location for the tomb being sought.






This photo shows the route that you're driving on in light brown.  The river that you pass is in blue and the arrow A marks the position of the 'tiny chapel' and the kandylakia.  The line in purple is the 180 m. path that you take 'to the right'. 




Here is a close-up of the east end of the route.  The blue line is the river that Goodison et al. call out.  The lat/lon pair is the position of the 'tiny' chapel.  The circle is centered by the kandylakia and is 30 m. in radius.  Not surprisingly that brings us directly to the road 'on the right' which leads south 180 m. to the tomb.  Our authors say: 'Present structure: Barely discernible raised irregular circular mound of stones, overgrown by vegetation.   D: ?c. 11 m.  ...' (2)





In this picture there is some ambiguity because the tomb cannot now be seen.  I supposed that maybe the structure was to the SE and there is a circular feature there.  But it is not large enough.  Its diameter is only about 2.7 m. and we're looking for a feature with a diameter of 11 m. (approx.).  I also want to point out the feature that I've called a 'Burn Circle' at the lower left.  I often see these more or less circular features in the olive orchards of Greece; they are really just circles of ash where the farmers have burnt orchard rubbish.  Wishful thinking often converts these things into tholoi.




Goodison et al. would have done their research before 2005.  I was able to find the 11/16/03 image of this area in Google Earth.  It does appear to show an anomaly about 7.5 m. to the NW of the NW corner of the barn.  No other image that I examined shows anything at all in that position.  I have drawn a circle of 11.0 meters in diameter centered on that spot to suggest where the tomb may have been.  I emphasize that this is supposition based on what our authors have told us.

So, perhaps the best position for our sought-after tomb is  35.056539° N, 24.982953° E.


No one claims that their work is error-free.  Substituting 140 for 1400 is a tiny error in a really fine and useful article.   In the field of computer science this would be labelled as just a bug.  I shudder to think how many of these things there must be in my own work.  It does illustrate, however, one of the real advantages that digital representation has over traditional print venues for scholarly work.  This article is going to be around for a long time and the description for Tomb no. 31 will be misleading people for as long as it exists.   If the information in Goodison et al. [2005]  (and several hundred others that I could name) were in the form of a database then such a flaw could be repaired for free and turned around in seconds.  It's just like software in that respect.  No professional expects software to be completely free of errors.  No moral opprobrium attaches to this.  Software authors recognize better than most other professionals that, when it comes to details, the human mind is basically trash.  As a result a large part of software implementation consists of making provision for keeping flaws under control.

One of those devices is the version numbering system.  As hideous as it may sound to an academic it may be time to start versioning articles and books.  The versioning information goes along with the article/book and would explain what has changed since the last version and why.  Of course this can only happen if these articles/books are online.   A consummation devoutly to be wished.

Of course I also think that articles and books shouldn't be printed at all.  It's outmoded.  Why commit errors to epistemological prison?

Finally, let me express my gratitude to Goodison and Guarita for providing this gazetteer from which I've learned so much.

Follow the telephone wires to Gargaliano Megas Kambos 1 (C390)


Gargaliani Megas Kambos is a Mycenaean site in Messenia that saw activity in the Late Helladic I-II and in the Late Hellladic IIIA – B.  We know about it  thanks to the Pylos Regional Archaeological Project which surveyed it in, I think, 1994.  The site is located in the extensive plains west of the town of Gargaliani in Messenia and is not very easy to find in all that flatness and in a landscape which is fundamentally nothing more than a carpet of olive trees.  As a result I’ve had it in the wrong position by about 300 m. ever since I added it to my Mycenaean Atlas.

Recently I acquired a copy of Davis and Bennet [2017] which is a retrospective of the PRAP effort and I have been revisiting many of the PRAP sites mentioned in my Mycenaean Atlas in the hope of finding additional information.  Here’s what Davis and Bennet have to say about Megas Kambos:

“The site lies on an elongated rise with a trigonometric point (104 masl) on top, ca. 3 km east of Marathopolis …  The rise is one in a series of knolls on the coastal plain west of the modern town of Gargaliani, and slopes gradually to the north, south, and west, with a more abrupt drop to the northeast.  On the southeastern slope is a bedrock cutting, perhaps a quarry.
Two distinct phases of ceramics are represented at the site: prehistoric, particularly LH I-II and III A-B, and Geometric-Roman.  A shaft-hole hammer-axe is probably of MH I date.”[1]

At the PRAP website there is additional material:

“The top is largely covered with maquis, dissected by goat paths, with some open grassy areas. The N and NW slopes are currently planted with grassy mature olives and there are occasional outcrops of bedrock. Intensive market gardening is being practiced on the E side of the hill. The S knoll has many exposed rock outcrops interspersed with grassy areas; at the bottom of the slope are extensive olive groves. On the SE slope is a bedrock cutting consisting of a vertical face with two short returns (perhaps a quarry)”[2]

So where is it?

There is one photograph in that book which, if it could be reproduced in Google Earth, would pinpoint the location of Megas Kambos.  Here’s the photograph:



Figure 1  Megas Kambos hill seen from the NE.   (Courtesy of The Department of Classics University of Cincinnati)

I’m using the color version which I found online.[3]   I encourage my readers to compare this post-processed photo with the original online.  One of my blog themes is that there is a lot of life left in these academic photos – but they need to be post-processed in order to bring out their full  potential.

Here is what the general area looks like in Google Earth:




Figure 2 Megas Kambos is somewhere in the center of this mono-cropped olive landscape.

The intersection of the two roads in the center of the picture is at 37.062327° N, 21.609643° E
Megas Kambos is in this picture – but where?  We are told that it is on a low hill; the ASL marker at the top is at 104 m. elevation.  But such a small hill is difficult to see in this landscape which has been terraformed for olive mono-cropping.

The key, believe it or not, is to locate in this landscape the telephone/electricity wires which are visible in Figure 1.  If you look carefully you’ll see that there is a near-by pole on the right and that it connects to two more poles that can be seen diminishing to the left (south).  The near pole is on a road and in my post-processed photo it’s clearer that this pole stands at an intersection of two field roads.  Can we find that pole/road/wire combination in this landscape?

Yes.   It turns out that we can.  If you look carefully at the clearest versions of these Google images (I’m using the Google Earth image from 11/28/2013) you’ll see a slight grey streak that turns out to be a telephone/electrical line.  Here’s the center of Figure 2 blown up with the lines indicated by arrows:



Figure 3 Wires at A.  They attach to a pole at B.

I traced every visible wire in this area to see whether I could create something recognizable.  Here’s the result:



Figure 4 Telephone wires marked in blue.  Poles marked and numbered at the vertices.

Here the wires are traced in blue.  The telephone poles at each vertice are marked.  The wire east of Pole 4 appears to end at a structure a few meters on.  The wire does continue past pole 3 to the south but I cannot trace it in Google Earth.  The wires to the north of pole 5 go back to the main grid.
The pole that appears to the right in Figure 1 is at position 1 here.  The two poles that are visible to the left in that photo are poles 2 and 3.  The wires in Figure 1 clearly connect 1,2, and 3 just as they do in Google Earth.   

Now I have to admit that I’m simply presenting the conclusion here and omitting all of my false starts; during this whole process I traced half the wires in northern Messenia.  But is this really the right solution?  If it is then it should now be possible to recreate the Figure 1 in Google Earth.  Here it is:



Figure 5 Megas Kambos Hill

Figure 1 reproduced for comparison


This is about as close as I can come in Google Earth to reproducing the photo in Figure 1.  I drew in the  poles using Photoshop.  The only real difference between this picture and Figure 1 is the wires that run from pole 1 to pole 4.  They show up in Google Earth but I can’t see them at all in Figure 1.  It’s possible that this line (to a single structure) was put up sometime in the quarter century since Figure 1 was taken.  I have no other explanation for that omission.

Well, time to wrap it all up with a map that shows everything in its place.  In the next photograph north is to the left.


Figure 6  White arrow marks photo position.  Megas Kambos is at the right.


In this photo the wires are as they were.  Megas Kambos hill is at the lower right.  The ‘low hill’ mentioned by Davis and Bennet is in the center.  It was from the lower slope of that hill (white arrow) that the photo of Megas Kambos was made.  The direction of the photo was to the south-west (and not to the north-east as Davis and Bennet would have it.[4]

The interested reader can safely download a .kml of this demonstration from Google Drive here

I still need to correct this in Helladic.info  Right now C390 is still in the wrong position and will be until I deliver a new database in the next couple of days.

A Possible CEM associated with the HAB at C397


In my last post I suggested that the correct position for C397 (UMME 139) was at 37.085266° N,  22.055458° E

In the same paragraph from Simpson which I quoted earlier we read this:

"About 500 m. to SW and considerably below the site just described, we noted prehistoric sherds about 2.50 m. down from the surface in the sides of a sunken track that leads up in a cleft between two hills to the convent of the Panayia.  The spot is only about 250 m. E of the outskirts of Thouria village.  There is a new concrete cistern about 30 m. to E, with a sluggish spring slightly higher to NE.  Among the most distinctive sherds are a flat ribbon handle of fine pink clay, a horizontal pinched handle of soft reddish brown fabric, and some plain rims and bases of darkish clay.  Several large pieces of thick pithoi might indicate that this was a cemetery.  The pottery seems to belong mainly to MH, but some may be LH.
  The material collected on the habitation site is not closely datable but confirms its use in prehistoric times.  It could have been associated with the "cemetery" below it."[1]

Also in Simpson and Dickinson [1979] this:

"... About 500 m. SW, some MH sherds and others which may be LH were noted about 2.5 m. down from the surface in the sides of a sunken track between two hills on the way to the Panayia convent.  Some large pithos fragments suggest that the track may have cut through a prehistoric cemetery."[2]

So.  From the previously located site move 500 m. to SW (225°) and we should be in the vicinity of the CEM.  Let's look at the map.







This is what it looks like when I apply all of Simpson's constraints.  The large yellow circle is centered on C397 and has a radius of 500 m.   The azimuth line of 225° (SW) is included for reference.

Near where the azimuth line meets the circle I noticed two things.  The first is what appears to be a cistern and 30 m. distant to the left (W) is a road.  Simpson et al. clearly state that their finds were at the side of a road in the (visible) strata and about 2.5 m. from the top.




Here I've zoomed in on that location.  The circle is 30 m. in radius and it is centered on what I consider to be a cistern.  Another meter or two and we're on the roadside.  I propose this as the approximate location for C5407, our supposed CEM.

All of this fits precisely with Simpson's directions - except for one thing.  Where is the convent of the Panayia and does it fit Simpson's text?  This poses a problem because I can find no religious establishment with that specific name.  The two best candidates might be 1) Ayios Vlasios at 37.079550° N, 22.055526° E and 2) another unnamed church at 37.082563 N, 22.058166 E.  The two candidates can be seen in the next photo:





Ayios Vlasios is to the S and connected to C5407 by a driveable field trail.  But it looks like it might be too small to be more than a simple country church.  Here it is in close-up:



The second church complex looks like this:



In this photo I think we have two things.  One is the church itself and the other seems nothing more than tin-roofed farm buildings.  Truthfully these two church complexes both appear to be simple country chapels.

Nonetheless I slightly prefer the second church, the unnamed one, simply because it is reached through a path between hills.  In the next photo I have exaggerated the vertical by a factor of 2 in order to bring this idea out.



This picture shows the entire area.  Our proposed CEM (C5407) is at the lower left.  Ayios Vlasios is at the lower right.  The large complex right in the center looks to me like a private home.  That leaves 'Church 2' at the upper right as the most likely candidate for the convent but -  I am not sure.  The path in red that I have labelled 'trail' is taken from Topoguide.  It is here to emphasize that it is possible to walk from C5407 to 'Church 2' by means of a trail that goes between two hills.

If anyone has more information about these several structures then I would very much like to hear.   For right now I propose 37.081622° N, 22.052162° E (C5407) as the most likely position for Simpson's MH/LH CEM.

The MH/LH Site 'Ayios Athanasios' (C397) near modern Thouria

A correspondent recently asked me for more detail about C397 which McDonald and Simpson identified as a potential habitation site near a church of Athanasios near Thouria in Messenia.  This gave me a chance to rethink my placement of this site; it's a good example of the hideous mess that a sketchily written description and slip-shod maps can create.  First let's go to the record:

In Messenia III we read this: "A small round knoll with a little barn on its summit rises about 200 m. NE of the chapel of Ayios Athanasios (bearing from the site to the chapel 225 degrees).  The modern village of Thouria (to be distinguished from ancient Thouria #78), on the main highway about 2 km. S of classical Thouria lies some 700 m. to SW of the site (bearing to the village church 257 degrees).
Obsidian chips and a few sherds of coarse "oatmeal" ware occur on the W terraces below the barn.  The total extent of the settlement was probably not more than 100 m. N-S by 60 m."[1]

In McDonald and Rapp [1972] it appears in Register A as site no. 139: "Thouria: Ayios Athanasios, 800 m E; 200 m NE of chapel of Ayios Athanasios.  Low knoll (barn on summit).  HAB. CEM? Frags. of obsidian; ..."[2]  There's a little more in the notice but that gives the gist of it.

This little 'settlement' reappears in Simpson and Dickinson [1979]: "A small settlement (maximum 100 m. N-S by 60 m.), marked only by obsidian and coarse pottery, on a hill c. 200 m. NE of the chapel of Ayios Athanasios and c. 800 m. E of modern Thouria village."[3]

Lots of good consistent information.  What are we looking for?

a. 200 m. NE (45 degrees) from the chapel of Ayios Athanasios.

b. From the village church of Thouria it is on a bearing of 77 degrees.

c. About 700 m. NE of modern Thouria.

Where is 'Ayios Athanasios' and where is the 'village church' of modern Thouria?  If we knew those things then we could find the site.

We should consult a map at this point in order to see where we are.


Modern Thouria and region.  From Topoguide


Here is the modern town of Thouria which is just a few km. NW of Kalamata in Messenia.  North of the town is a church labelled 'Aghios Athansios' (Arrow A).  This is too far north of Thouria to be the Ayios Athansios referred to by Simpson et al.  The church intended by our authors to be understood as Ayios Athanasios is at arrow B and I'm going to show that that must be the case in just a moment.  I should just say here that I have not been able to find the specific name for that church (B) from any of the sources that I have consulted.

Now let's take a look at the town of Thouria itself.  Perhaps we can identify the other 'village church' that Simpson mentions.  In this image from Google Earth I have marked three  prominent churches in modern Thouria.  The one to the left (C) is Hagiou Athanasiou (yes, another) and the one to the right (A) is Hagioi Theodoroi Thourias.  I have not been able to find the name of the large cemetery church at B.



I list the positions of these churches in tabular form:

A. Hagioi Theodoroi Thourias, 37.084460°,  22.051255°
B. Unnamed, 37.085319°, 22.047446°
C. Hagiou Athanasiou, 37.084310°, 22.047087°

Which of these did Simpson refer to when he talked about the bearing from the MH site being 'to the village church 257 degrees'?

In this next picture I've drawn 77° (257 - 180) azimuths from each of the three churches.





Simpson's 'Ayioi Athanasioi' at B


We know that the site is on one of these azimuth lines.  It must also be 200 m. to the NW of a church called 'Ayios Athanasios'.  The only church structure that fits that 200 m. constraint is at B.  Here is what it looks like when we put it all together:





Here I assemble all the constraints.  The church intended by Simpson et al. to be understood as 'Ayios Athanasios' is at B.  The circle is of 200 m. radius and centered on B.  The straight line from B is on an azimuth of 45° (NW).  These three constraints, the straight line constraint from Hagioi Theodoroi at A, the straight line constraint from the church of 'Ayios Athanasios' at B, and the distance constraint (the circle) centered on B, all come together at C where I've placed the site with high confidence.

How do I know that the church at B is what Simpson and others intended to be understood as 'Ayios Athanasios'? 

I don't. 

But it's the only church that fits the constraints.  Informants tell me that there are at least four churches in the Thouria region that are named for the saint.  Whether the church at B really bears that name is uncertain.  It may actually bear that name (or may have in the 1950's - 60's) or Simpson may have been misinformed about it.  If any of my readers know more about this then I would very much like to hear.  In the meantime that's my story for C397 and I'm sticking to it.


C397 is placed at 37.085266° N,  22.055458° E
Church at B, 'Ayioi Athanasioi', is at 37.084185° N, 22.053902° E


I haven't updated my on-line database to reflect this new information since March 21 so the online description of C397 won't agree with this post quite yet.  I won't update the DB for another couple of days.

Simpson and others have thought also to identify a cemetery nearby.  I'll deal with that next time.

Reader reacts to my remarks on Scott


A correspondent has written me about my blog post reviewing Scott's Against the Grain.

"I suppose the main point about grain is that it can be stored for some (long) time given the right conditions. The same might be said for beans and most pulses. All that needs to be done to keep this form of "preserved wealth" is to keep it dry. Tubers like yams and potatoes cannot be so easily stored for more than (say) one season and so represent a very temporary form of wealth.
But, to be honest, a goat is almost as useful as a sack of corn. It keeps itself "fresh" and can even grow in size while waited to be "liquidated". If anything one might hypothesise that herding as much as grain production was the genesis of tax collection. "


My reply:


Thank you for your letter.  You've given me an opportunity to restate some things.

There is much in Scott's book that is quite correct.  He is right that early state formation is associated with transfer of goods from producers to a new consumer class (whoever they are).  He is right that grains make good candidates for such a transfer.  He is right that very often outsiders forcibly appropriate wealth from communities of producers but by stating that robbery is the origin of the state misses 99% of what we can know from historical examples.

If the business model of a gang of bandits consists of stripping communities of their wealth then the likelihood of the appropriators now becoming governors is quite small.  If Scott doesn't believe this then he should show us how bandits form a state.  I'm sure that this has been possible under some circumstances and I would read Scott on this subject with great interest.  As yet he has not told us how this works.

By emphasizing grains he misses the fact that wealth transfer can consist of products from the entire ecosystem.  It doesn't have to be just food stuffs.  He misses the appropriation of subsistence as well as luxury goods.  States sometimes emphasize one over the other and this can have implications for state formation.  But a discussion of this is absent in Scott.  He also misses the larger picture of how human associations change in a way such that the result is what we identify as a 'state'.  He never discusses the well-documented fact that the state does not spring de novo from a group of villages but goes through a long process of intermediate transformations; rank societies both achievement and hereditary are found more often in the historical record than states.  Scott omits this.    To him it's all the same - the State is a protectionist gang.

You seem to emphasize the idea that certain goods are more collectible because they are less perishable.  Why would you (or Scott) think that?  If appropriable goods are perishable then why wouldn't tax collectors come more often?  Or does Scott suppose that tax collectors in ancient Mesopotamia always came once a year on April 15?   I don't want to promulgate 'Just So' stories but I really cannot see the force of the argument from perishability.

Scott never really does characterize specific tax-collecting practices.  He has created a tax straw-man and he uses it to avoid the real questions about the complexities inherent in all human associations.  The formation of societies above the tribal level is a complex one with many variations.  The best discussion of such topics is Flannery and Marcus [2012], The Creation of Inequality.  (And please Google the many reviews of this work.)  This is what discussion of the State looks like when one is not grinding an ideological axe.  I cannot recommend it enough.

Correspondent Comments on the Suitability of Pleiades Data for Scholars


A friend of mine replied to my post on the inaccuracy and unsuitability of Pleiades data for scholarly work.  (http://mycenaeanatlasproject.blogspot.com/2018/02/pleiades-data-does-crowd-sourcing-for.html)

I reproduce his letter here:

"Pleiades isn't structured to provide a single, accurate set of coordinates, though I think it hopes to evolve in that direction. Its most useful role currently is as a set of identifiers that allow links to superior gazetteers. For example, the huge error for ancient Messene is the result of displaying a calculated representative point that includes one spurious DARMC location (from the modern village of Messene), in addition to a mildly inaccurate DARMC location plus a very accurate DARE location. (DARE has assimilated a bunch of Google Earth-validated ToposText points for Greece, and from other sources as well, but uses Pleiades IDs as an easy pivot to other resources). Some of the tools Pleiades funding has produced for the purpose of improving its data are not being used very much -- one problem being a technological gap between laborious on-the-ground collectors ... and people who automate things."

Now I look at it piece by piece (original letter in red, my replies in black)

"Pleiades isn't structured to provide a single, accurate set of coordinates,"

So then where do we go from here?

" ..., though I think it hopes to evolve in that direction."

Spoiler alert: they're not going to. This would involve an enormous amount of work - actual scholarship. They're not going to commit to this because they think that this can be done on the cheap - through copying other data sets or through crowd sourcing. That's not the way that any of this works. My experience with them is that they will correct an error if you bring it forcefully to their attention but not otherwise.

"For example, the huge error for ancient Messene is the result of displaying a calculated representative point that includes one spurious DARMC location (from the modern village of Messene), in addition to a mildly inaccurate DARMC location plus a very accurate DARE location. (DARE has assimilated a bunch of Google Earth-validated ToposText points for Greece, and from other sources as well, but uses Pleiades IDs as an easy pivot to other resources). "

You've explained Messene but what about all the other errors? Nor have you questioned my estimate that approx. 1/3 of Pleiades has serious errors. What you're describing sounds like a real incestuous tangle. I don't even want to get into unpacking this beyond saying that topographical accuracy does not come from copying other data sets. It's like the old saw about buying a used car: you're just buying someone else's problems.

" Some of the tools Pleiades funding has produced for the purpose of improving its data are not being used very much -- one problem being a technological gap between laborious on-the-ground collectors (like me) and people who automate things. "

Sounds like you're describing Recogito. Is that what you mean? Are there other tools that they support? I tried out their conversion tool Geocollider. It failed miserably.

Everything about Pleiades/Pelagios/Peripleo is sham.  The Barrington Atlas data was useful for its printed purpose but now they're trying to roll that data over into the digital world where its approximative nature makes it unfit for use. And they've wrapped the whole thing up with bad and outmoded ideas - not from scholarly practice, from anthropology or toponymy or history or classical studies or any other relevant discipline - but from computer science. None of what they're doing (crowd sourcing and linked data) has anything to do with any scholarly practice or purpose but this is what they're selling and they're getting pots of money for it. In the end actual scholars wind up exactly where they started - having to do the topography of the Mediterranean from scratch. I actually know a fellow (from a very prestigious school) who's preparing a study of Mediterranean habitations. I was shown one of his spreadsheets and it was stuffed with errors since he had relied on Pleiades. In fact that's where my blog post came from.

I've asked myself what their game is. I suspect that what they want is to license their data (or perhaps their follow-on project Pelagios/Peripleo) to schools for so much per seat and deny access to non-customers. That's a time-honored approach in Computer Science. First get a lot of contributors to fork over their work for nothing under the name of something noble-sounding like 'Open Data' or the 'Semantic Web'. Second, license the whole to third parties and keep all the money.

Although I'm not sure that they can really carry this out successfully because it's the Underpants Gnomes business model.

Icons for the Mycenaean Atlas Project




Three years ago when I first began to develop the Atlas of theMycenaean Bronze Age, I had an image in mind of a landscape scattered with icons that indicated what was found where.  I wanted a picture of the landscape of the Bronze Age.  Of course the work of specifying actual locations for Bronze Age find spots came first.  And up until now the web site has simply displayed orange paddle icons for any find whether it was a palace or a single potsherd.  It looked like this:




Not very helpful to be confronted with a map that was thickly populated with this icon because each icon had to be clicked on before you could tell even roughly what it was.

Now I’m pleased to announce that I have implemented a full range of pictorial icons that give some idea what a particular find is.  First is the ‘habitation’ icon


Currently this will be used to designate any habitation, house, building, palace, etc.

The artifacts icon will be used to symbolize any site from which the most significant finds consist of more than sherds.  So axes, blades, figurines, pins, loom weights, etc. will be symbolized with this:




This icon depicts a sword, an ax-head, and a psi-figurine.

Cemeteries will be symbolized with this icon:



Chamber Tombs will by symbolized like this:


…and tholoi like this:



Mounds, tumuli, and magoulas are symbolized with a mound icon:



Generalized vases finds are depicted like this:


Sites that are characterized principally by sherds use this icon:



Now that I have them displayed it appears that the quality is poor and the images blurry.  Remember that the originals are 32 pixels square and have been grossly enlarged to be visible in this post.   They look much better when displayed on the map.  Here's a map of Achaea with all the icons showing:


I think this makes a nice addition to the site and gives it a more intuitive appearance and feel.

There are some cautions:

First, many sites can be characterized in a multitude of ways.  Sites can be habitations, have mounds of sherds, and incorporate burials.  What icon do I use in that case?  I have attempted to use an icon that accounts for the preponderant importance of the site.  In the previous case I would use a habitation icon since the idea of habitation is probably the most important thing about that site.  There are, on the other hand, many sites which are indicated by an abundance of sherds and which are thought to have been sites but with no other evidence than the just sherds.  In that case I would probably use the sherds icon.  

So the icons are just indicators.  They're an attempt  to make the landscape more intuitively understandable but keep in mind that a single icon cannot and will not fully characterize the site. 

Aside from that the new icons operate in exactly the same way that the old ones did.  They feature tool-tips and an info box with a link to a full page report on the site.  There are still a few of the old orange paddle icons around.  These are for sites such as caves, wells, walls, etc. for which no new icons have been designed.

There have been no icon changes for the modern features.  They are still shown by a red paddle with an 'F' on it.

Here's another example - a map of the Argolid and southern Attica in the LHIII:




Software elements on the helladic.info website have been updated to support the new icons.

In addition to the icons there is a new database which was delivered on March 2, 2018.  It adds sundry minor corrections as well as thirty new sites, primarily in Crete.  The new DB is rev 0053.
