What does 'site aspect' mean? Reviewing a paper by Malaperdas and Zacharias


I’ve been looking at Malaperdas and Zacharias’ paper from 2018 and using the helladic.info Site Aspect pages to check some of their figures.[1]  This very interesting paper examines 18 Mycenaean sites in Messenia from the geophysiological viewpoint. The authors examine site aspect, slopes, water resources, and site geology in an attempt to derive clues to explain why the Mycenaeans established settlements where they did.

The concept of site aspect is a complex one. First there’s the problem of determining what aspect actually is. I take this word to mean the direction of the largest slope. Aspect can change radically as one gets further away from the site. I’m not aware that there is an agreed distance at which the slopes for determining aspect should be calculated.

In the Mycenaean Atlas Project each site elevation is matched to eight other elevations. These ‘sample’ elevations are taken at 150 m and 300 m in each cardinal direction (N, S, E, and W). That means there are two slopes calculable for each site in each of the four directions, one at 150 m and one at 300 m.   For each site the direction with largest slope at 150 m and direction with the largest slope at 300 m are used to determine ‘Site Aspect’. There are ten possible results: N, E, S, W, NW, NE, SW, SE, NS, and EW. For each site the aspects at 150 m and at 300 m may very well differ.

Site Aspect Map for Messenia. Blue arrows indicate aspect.  Clicking on
an arrow brings up an info-box for that site.  Mousing over the arrow
gives you the name of that site.


More than the problem of determining aspect mathematically there is the consideration that many sites are large and complex. It is quite reasonable to associate different parts of a site with different aspects. I do not generally take this factor into account in the Mycenaean Atlas.

Sites with very low slopes (< 3º) in every direction have no meaningful aspect in my opinion.

Malaperdas and Zacharias [2018] are not explicit about how site aspect was determined. I compared my site aspect results to theirs. (All numbers in the form Cnnn or Cnnnn are references to the Mycenaean Atlas Project at www.helladic.info.

1. Ano Englianos (C219). This large and complex site lies on both sides of a ridge that runs approximately NE-SW. Nestor’s Palace itself actually sits on a part of that ridge that runs more directly EW. Malaperdas and Zacharias [2018] give its aspect as ‘South’. In fact, its real aspect is North-West-South, that is, orthogonally away from its ridge in both directions (NS) and with a clear view of the ocean (W).

2. Koryfasio-Beylerbey (C238). This little site sits on top of a tiny plateau (elev. 31 m. a.s.l.) and has very little slope in any direction. Only to the N and W at 150 m. does its slope amount to ‘slight’. Malaperdas and Zacharias have its aspect as ‘Southeast’. A better value would be NW but, in fact, aspect has little meaning for this site.

3. Iklaina (C223). I have taken our authors to mean ‘Ikaina-Traganes’ which is the major site on the Iklaina plateau. Iklaina is located near the S edge of a large plateau which falls away precipitously to the S and W but that’s not enough to give the site a south-westerly aspect. In fact C223 has no more or less aspect than any other site on that plateau which is essentially flat.

4. Koukounara (C421). Koukounara is part of an enormous complex of BA sites (mostly tombs) each of which differs from the others. It has never, to my knowledge, been adequately mapped.[2] The first task is to try and figure out what Malaperdas and Zacharias mean when they say ‘Koukounara’. The Potamou tou Arapi is a rema or gully (as we say in America) that runs roughly N-S. At one point two separate remas come together and create a southwest-facing promontory and the little settlement (C421) sits on that promontory facing S. I have its aspect as West at 150 m and South at 300 m. so I make its aspect to be predominantly S and W. Malaperdas et al. make this aspect to be S and E.

5. Yialova: Palaiochori (C249). For the exact location of this settlement see McDonald and Simpson [1961].[3] It sits on the west end of a ridge running EW. We are explicitly told that the site sits on the summit of the westernmost bump on that ridge.[4] As a result it has aspect to the N, W, and S. Malaperdas’ suggested value of ‘Southeast’ is not adequate.

6. Metaxada-Kalopsana (C203). This little site lies at the bottom of a valley which runs N-S. We would expect, by inspection, that its aspects would be N-S. But it also lies on a small ridge running E-W in that valley and so it has a non-negligible westerly slope. Nevertheless, I make its aspect to be South at both distances. Malaperdas et al. make the aspect here to be Southeast. I do not see how that is possible.

7. Rizomylos-Nichoria (C159). Nichoria is situated on a ridge that runs nearly perfectly E-W. (260º). A road ran through the settlement and parallel to the ridge. It is completely open on all sides and, while a little valley does open to the south, the idea of aspect is nearly meaningless with respect to this site. Its site would not, for example, shelter it from the north wind.

8. Thouria-Ellinika (C403). I take Malaperdas et al. to be referring to a site which, in the Mycenaean Atlas, I call C403. This is the same as the ‘Myc. Site’ on Richard Hope Simpson’s map in his article from 1966 [5] This little settlement sits directly on top of the Thouria ridge and just to the south of the chamber tomb complex dug into that ridge. Mathematically its aspect is East and West and inspection confirms this. Its slope to the south is slight (4.29 and 4.76 at 150m and 300m respectively).

9. Pidma – Agios Ioannis (C113). This site is open to the N, W, and S. It backs against those cliffs which bound the Pamisos valley on the east. We would expect its dominant aspect to be away from the cliffs and to the W. This is so but the slopes to the three cardinal directions are so slight that it can hardly be said to have aspect at all.

10. Kalamata Kastro (C111). The Kastro sits on top of a small plateau and is open to the sky in all directions. Even though there is strong slope in all directions at 150m this is purely an artifact of the plateau edge and cannot figure into any calculation of aspect. The concept of aspect at this site does not apply.

11. Kardamyli Kastro (C103). The location of the Kastro of Kardamyle is given in Simpson [1957] 234-6. It is the high plateau (+110 m) that stretches out about 800 m to the NW of the modern town. Simpson provides an excellent map.[6] Malaverdas et al. seem to have picked a different place. To judge by their reported elevation they apparently chose the little height about 400 m to the southwest. But this is not the Kastro of Kardamyle. Simpson reports activities on both sides of this high acropolis. Indeed, activities on the south side have southern aspect and activities on the north side have northern aspect. The acropolis itself, however, is flat and has both N, W, and S aspect. It has, for example, shelter only from the east. Otherwise none.

12. Leuktra: Stoupa (C447) Southeast of the little town of Stoupa a volcanic plug rises suddenly out of the plain to a height of about 50 m. (72 m a.s.l.) above the surrounding level. The top of this plug is relatively flat and it measures ca. 118 m. northeast to southwest, and as much as 35 m. northwest-southeast at its widest point. In the LH a Mycenaean site of little consequence was placed here – sherds have been found. Again, as in previous examples, this site has no aspect. It is completely open in every direction. The Mycenaean Atlas reports strong slope in every direction but that is not enough to establish any directional aspect.

13. Kato Melpia: Krebeni (C121). You can see Kato Melpia in Google Street View at the location 37.328513°, 21.933230° and looking directly N. Kato Melpia is not the high peaks but the shelf lying about half-way down. It has some shelter from the N and I make its aspect to be south and west. In this I agree with Malaperdas et al.

14. Malthi-Gouves (C149) The site selected by Malaperdas et al. Is not Malthi-Gouves. Judging by their reported elevation they seem to have selected the primary tholos at the bottom of the Malthi hill (C1207), and not the actual settlement which is at the top of the hill about 125 m. above it. The settlement itself covers the top of the hill and is unsheltered in every direction. The concept of aspect really does not apply to it although inspection of the photographs here() show a slight incline towards the south. The site seems, however, to have been chosen purely for the sake of the visibility it affords over the central Soulima valley. The site selected by Malaperdas as ‘Malthi’ is a large tholos tomb, not badly preserved, but which is tucked into the Malthi ridge at its base on the West side. They give it an aspect of southeast but I do not see what relevance aspect has in this context.[7]

15. Dorio-Kontra (C126). The little settlement of Dorio sits on the top of a conical hill more than 100 m above the surrounding valley of Stenyklaros. As such it has no aspect. The nearest hills to the N are about 3 km distant. It seems clear that this site was chosen for the visibility it has over its surrounds.

16. Filiatra – Ayios Christoforos (C188). This site is located on a plateau. Ayios Christoforos is where it is probably because it affords a view of the entire coast to the west. Immediately to its N is a large hill which shelters it from the N. Its aspect is S and W.

17. Myron-Peristeria (C183). This is a complex site with multiple aspects. Aside from the several tholoi (placed, I am convinced, for maximum visibility), C183 is a building occupying a position which Simpson and Dickinson [1979] 167 call an ‘acropolis’. Like Malthi (C149), it overlooks the Soulima valley to the north and its measurable aspect is N and W.

18. Mouriatadha-Elliniko (C180). This site occupies a northwest-southeast ridge in the center of a valley running EW. It sits on the top and south of this little ridge but immediately to its south is another and larger ridge running east-west. To the extent that this settlement has any aspect at all it is east-west.

Conclusion

If there are any lessons to be learned from looking at settlement site aspect they are these:

1. Sites near the sea usually face the sea.

2. Whichever way the slope faces the site faces the same direction. That is if a ridge slopes down to the N then sites on that slope face N, etc. There are about as many sites on N-facing slopes as S-facing.

3. Sites on top of a ridge or on saddles have aspect in opposite directions orthogonally away from the direction in which the ridge runs.

4. Aspect is much less meaningful for sites on peaks or in valleys (or located on plateaus) and for sites on ground where the slope is less than 0.05 (2.86°) in any direction.

These are general ideas only and can be heavily affected by local conditions: access to water, tillable fields, etc.

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.

Blog Posts Concerning the Isthmian Wall

Since 2023 a number of posts concerning the Isthmian Wall and how we located its remaining segments, have appeared on this blog.  This post ...
