Colgate EALL (2)

Design work on the remodel of the Colgate East Asian Language Laboratory is getting closer to the finish line. I thought I’d share some sketches I’ve come up with for the space, though keep in mind this is not completely finalized as of yet.

The space consists of a pair of small rooms linked by a hallway, and along the hallway are faculty offices. The first space I worked on was the Japanese room, occupying a relatively small niche of space. From the hallway, the entry to the space is indicated by a small hanging panel, reminiscent of a ranma:

I’ve applied some ‘plant on’ posts, and nageshi, with a form of wainscot on the wall which looks similar to a exterior wall treatment seen on many Japanese structures.

Upon crossing under the ranma, a turn to the left gives a view of the alcove, with tokonoma (right) and toko-waki (left):

The benches are unusual for a Japanese traditional space of course, but in this situation the people coming into the space and sitting will be wearing, as per usual in the west, their street shoes and won’t be parking themselves on tatami on the floor. So, some compromise was needed to make the alcove work with a sitting viewer, in a rather cramped space. The department head, who is Japanese, was pleased with the arrangement.

There are three simple benches and a small table with splayed legs. The benches can be pulled out of the way to reveal sliding doors under the alcove, where items for display in the alcove and on the chigai-dana (staggered shelves) will be stored.

Heading the other way down the hall, bring the viewer to the 'Chinese’ room, which, like the Japanese space, is an area defined by a hanging piece of joined woodwork:

In the room proper is an insert window frame with a lattice echoing that of the one at the room’s entry:

It is likely that some changes may yet be made to this lattice so that it conforms better with the existing sash window mullions to the rear. Possibly the entry hanging lattice might recieve a backing solid wood panel as well. As it is, we’ve been through several design iterations with the lattice arrangement, of which, or course, there are innumerable possible variations.

Turning the corner of the Chinese room and one sees a small table with a set of Chinese-style chairs, along with a bumped-out section with a framework with re-entrant corners, which will serve as a window to a series of interchangeable images behind:

The design phase is drawing near to a conclusion, it would appear, so I am probably about 6~8 weeks out from getting started on fabrication, which will need to be scheduled in with the other cabinet build with which I am currently occupied.

That’s it for this juncture, thanks for visiting!

Parsing the Parthenon (II)

In the first post in the short series, I outlined some of the Parthenon’s history, finishing up with Morosini trying to loot the structure and remove the parts back to Venice. It is good he was only successful to a limited degree in that regard, though Scottish nobleman Thomas Bruce, aka the Earl of Elgin, did a vast amount more thievery under a dubious note of permission from the Sultan, the results of which can be found in the British Museum today. It’s nice that those examples are preserved and available to view, however they are the cultural property of Greece.

The topics of vandalism and theft of Parthenon relics, not to mention from a great many other Greece historical sites is a subject which could fill many volumes. What I want to focus on in this second post though is the building itself, as it was truly remarkable in its sophistication.


The Grand Tour.

Starting in about 1660, wealthy young Englishmen began taking a post-‘Oxbridge' (Oxford and Cambridge Universities) trekked through (mostly) France and Italy in search of art, culture and the roots of Western civilization. With nearly unlimited funds, aristocratic connections and months (or years) to roam, they commissioned paintings, perfected their language skills and mingled with the upper crust of the Continent. The Grand Tour offered a liberal education, and the opportunity to acquire things otherwise unavailable at home, lending an air of accomplishment and prestige to the traveller. Grand Tourists would return with crates full of books, works of art, scientific instruments, and cultural artifacts – from snuff boxes and paperweights, to altars, fountains, and statuary – to be displayed in libraries, cabinets, gardens, drawing rooms, and galleries built for that purpose. “Look at me!. I’m wealthy and cultured!”

The Grand tour went as far west as Italy, and did not venture into Greece as it was under control of the Ottoman Empire, and a country that, since the destruction of the Parthenon in 1687 and the expulsion of the Venetians, largely had been closed to Europeans.  However, with an easing of diplomatic relations in the mid-eighteenth century, it became possible for an intrepid traveler to visit Greece. 

In 1751, the English architects James Stuart and Nicholas Revett announced a proposal they had conceived of several years earlier in Rome. Their intention was to systematically survey the architectural monuments of Athens in three folio volumes, with engraved plates and a descriptive text. The venture received funding from a club called the Society of the Dilletanti

For the next two years Stuart made notes and picturesque gouache paintings of the actual state of the principal monuments, and Revett did the measured drawings. After working for about two years, the political situation arising from the Ottoman occupation that had commenced in 1458 became too hot, compelling their departure in March 1753.

Upon return, Stuart set to work to write a multi-volume work on his discoveries, however he turned out to not be the most focussed individual, which frustrated many of the readers who had pre-paid a subscription to the promised volumes. He married his maid and dabbled in architectural commissions.

Finally, in 1762 out came The Antiquities of Athens: Measured and Delineated by James Stuart and Nicholas Revett, Painters and ArchitectsPublished in 4 volumes and a Supplement, the second of which, coming out years after the first, described the Parthenon:

In Volume II one finds a view of the front of the Parthenon:

They took meticulous measurements of the structures and in particular showed many detailed views of the remaining carved figures decorating the structure, however they completely missed on some crucial details, like column entasis.

Europeans were familiar with column entasis from Roman examples which were themselves patterned after Greek architecture. In the case of the Parthenon the entasis was so slight on the columns that is was missed altogether by Stuart and Revett. The entasis of columns in Greek examples was not observed until 1810, by Cockerell.

It should be further noted that, up to this point in time, Roman culture and art was considered the ultimate achievement of Antiquity. Discovery of Greek classic architecture, however, was about to rock that boat.

Interestingly, a Frenchman named Julien-David Le Roy got wind of Stuart and Revett’s plan to be the first to examine ancient Greek architecture, so he determined for some reason to beat them to the punch. He was living in Rome at the time, and did not reach Athens until 1755, some time after Stuart and Revett has sailed back to England. He remained a few months, and with the help of some Capucine monks was able to survey many structures. Upon return to Paris in the same year, he set to work feverishly, wanting to get his work out ahead of Stuart and Revett.

The result was Les Ruines des Plus Beaux Monuments de la Grèce by Julien-David Le Roy, published in 1758:

Unlike Stuart and Revett, Le Roy was not interested in simply making precise measurements of structures, but was more interested in conveying the spirit of the architecture as he saw it;

Part of the south side of the Parthenon is illustrated:

On the metopes are scenes from the Battle of the Lapiths and Centaurs, also known as the Centauromachy, in which the mythological Athenian king Theseus took part. Interestingly, the author added to this side a pediment as well. He was not a stickler for accuracy it seems.

Le Roy’s 'The Parthenon: 1. Plan of the temple. 2. West side of the temple’:

On the pediment is depicted the battle of Athena with Poseidon. On the metopes the Centauromachy. 

In fact, the Centauromachy is on the south side of the temple and not in the west, as the author shows.

Publication of Le Roy’s work caused quite a stir. The next year, exasperated at the delay with Stuart, Revett quit the undertaking altogether. Stuart, too, must have been annoyed that he had allowed himself to be pre-empted by his rival, a Frenchman who had not even arrived in Athens until after he had departed nearly a year before. (Even more maddening, an unauthorized version appeared in English the next year.) Critical of Le Roy’s inaccurate drawings and perfunctory observations, Stuart set about completely revising his text to refute them. Four years later, in December 1762, the first volume of The Antiquities of Athens finally appeared.

In the preface, Stuart declared that he, at least, was determined “to avoid Haste, and System, those most dangerous enemies to accuracy and fidelity, for we had frequently, with great regret, observed their bad effects in many, otherwise excellent, Works of this kind.” Railing against Le Roy, every misunderstanding and inaccuracy were itemized. There were insinuations of plagiarism and charges that descriptions had been taken from others and not made directly, as well as failures to recognize monuments for what they were (e.g., the gateway to the Roman Agora and Hadrian’s Library).

You see, pissing matches go way back.

Both Stuart’s work and Le Roy’s were hugely influential and Stuart’s work in particular had both a profound influence on the Greek Revival and ushered in an age of precision measurement of ancient architecture. In the nineteenth century especially, Stuart’s work served architects and designers as a principal source book for the Greek orders and decorative motifs.

Bringing this matter home to a US audience, I can make mention of the first person to write pattern books on architecture in the United States, namely Asher Benjamin, whose works brought architectural history, style and geometry to ordinary builders in the field. One of his most influential works is The Practical House Carpenter, published in 1843.

To quote from the Wikipedia page on Benjamin,
“The archeological sources of his designs were scrupulously cited, from the Temple of Hephaestus in Athens to the Arch of Titus in Rome. Other architects, including Ithiel Town and Ammi B. Young, freely assimilated his plans, as did innumerable carpenters. Indeed, the charm of many early New England towns owes a debt to Asher Benjamin. ”
The Temple of Hephaestus in Athens was detailed in Stuart’s 3rd volume. Here’s a view of the front of that building in that text:

This is another widely admired and copied building - including, somewhat near to where I live, the Vermont State House in Montpelier.  Hephaestus, by the way, was the patron god of blacksmiths, metalworking, carpenters, craftsmen, artisans, sculptors, metallurgy, fire, and volcanoes, so if you are looking for an alternate direction in which to worship, look no further. :^)

Here is plate 4 from Benjamin’s The Practical House Carpenter, showing the Doric order on the same structure, likely an image taken directly from Stuart’s text:

It seems that The Practical House Carpenter represented a change in sentiment for Benjamin in terms of his desire to bring Grecian architecture to an American audience. From the Preface:

Thomas Jefferson owned a copy of the first volume of The Antiquities of Athens. In 1803, he appointed Benjamin Henry Latrobe as surveyor of public building in the United States, and Latrobe designed a number of important public buildings in Washington, D.C. and Philadelphia, including work on the United States Capitol and the Bank of Pennsylvania.

Besides the US, the Greek Revival was of course hugely influential in England, Scotland, France and Germany - even Russia.


The reader may recall from the first post that Morosini’s effort to capture Athens, resulting in the destruction of the Parthenon, was a Phyrric victory, in that a year later the Ottoman turks recaptured the city.  They retained control of Greece and surrounding territories to the east and south, consolidating what became termed the Ottoman Empire. While the Ottoman Empire lasted until 1922, Greece was not a happy participant within in. The Greek War of Independence began in 1821, and ran until independence was gained in 1832. The great powers of the day, Russia, Britain and France, naturally intervened in this war and helped the Greeks gain victory and expel the Ottoman Turks. Greece was finally recognized as an independent nation in the Treaty of Constantinople of May 1832. By agreement between the controlling powers, a new king ascended the throne, and he was…  a German, Otto, second son of Bavarian King Ludwig I. A loan of 60 million francs was also provided, with 'conditions’, along with 3500 troops to protect him. He was still a minor when he ascended the throne. This arrangement was termed the 'Hegemonic Constitution’. Otto spent one decade as absolute monarch introducing an expanded legislation in an effort to westernize the country without taking into account the local traditions of the country. Although King Otto tried to function as an absolute monarch, as Thomas Gallant writes, he “was neither ruthless enough to be feared, nor compassionate enough to be loved, nor competent enough to be respected.”  Otto strived to placate the controlling powers by playing them off against one another, in an effort to keep the foreign loans rolling in, and this strategy, in the end, pleased no one.

The discontent against the authoritarian pattern of his policy festered and eventually his subjects’ demands for a Constitution proved overwhelming, and in the face of an armed but bloodless insurrection Otto in 1843 granted a constitution. However he rigged the election using fraud and terror. Ah, the old playbook, eh? In 1862 he was deposed while out of the country, and died in Bavaria, still apparently usually seen wearing Greek traditional regalia, in 1867.

That brief rule by the Bavarian Otto was to have significant bearing upon academic investigations of ancient Greek antiquities. The Bavarian King appointed other Germans to important posts within the government, and his first task as king was to make a detailed archaeological and topographic survey of Athens. After a time a Hungarian, Joseph Hoffer, became the official architect of the recently founded Greek kingdom and directed and superintended, in 1836, the clearing away of  rubbish from the platform of the Parthenon. At last one could truly see the structure. And the view was unexpected, as it revealed something really surprising: curvature.

Now we reach the meat of the topic, and the very reason I became so interested in the Parthenon of late and wanted to write about it.

The phenomenon of curvature at the Parthenon was first described in Hoffer’s essay “Das Parthenon zu Athen, in seinen Hauptteilen neu gemessen” published in 1838. Hoffer’s work was apparently largely ignored in his native Hungary, despite his incredible discoveries.

Colgate EALL

Colgate University, located in upstate New York, with nearly 2900 students, ranks in the top 15 in the country. A while back the department head of the East Asian Language Laboratory contacted me with a project. The wanted to remodel their department, consisting of 5 faculty offices along a hallway, with a small room at one end and an even smaller niche at the other, to better reflect the ethos of the department. They wanted one room to be modeled so as to give a Chinese feel, and the smaller niche to have a Japanese motif, and for both areas to provide a place to people to sit and relax while waiting to meet with professors.

The provided me with some measured sketches of the various rooms, photos of the sorts of details they were looking for, and some of the building blueprints. Of course, building blueprints and ‘what actually was built’ can sometimes vary, and trusting the room dimensions taken and jotted down by someone who does not normally do such things can be unwise for a fabricator. Best to confirm the numbers for yourself before getting too far along. But given the irregular shape of the rooms involved, it was all too possible as well to go to site and make an error in taking dimensions somehow, either writing down the wrong number, or ascribing a dimension in one place to another, or just forgetting to measure something that later on proves to be important.

Now, Colgate is some 4 hours drive away from where I live, so the prospect of making several 8+hour trips back and forth to take dimensions was, well, seeming inefficient at best. I had recently however received some information from Trimble (the company which owns SketchUp) of a new 3D scanning product called Canvas IO. Here’s the video:

Sure looks pretty whizz-bang, huh? It certainly seemed to offer advantages over physically going to site and manually taking measurements.

Looking over the Canvas IO website, they make the following claim for accuracy:

Across the case studies we’ve run with professional out in the field — using Canvas on real-world projects — we see that most measurements are within 1-2% of what’s verified manually by tape measure, laser range-finder, or existing blueprint. 

So, after looking it over and seeing the possibilities, and liking that direct export from the captured data into SketchUp was offered, I thought it would be a good way to go. Unfortunately I do not have an Ipad, but a few emails later I had managed to convince the Colgate IT department to purchase the device ($500) and to go and scan the room.

It took a few weeks, but eventually I received the first scan, which opened in SketchUp like this:

It looked good! The depiction looked faithful to the room layout I had seen in other drawings they had provided.

The ceiling of the room was saved as a group or component, so one click to disappear that part and the contents were revealed:

That also looked pretty good.

Now, at the preliminary phase of the design discussion with Colgate, I had been suggesting they might want to look at using Japanese and Chinese ceiling treatments as a way of defining the spaces, so I was curious to see what details, like the locations of sprinklers, HVAC outlets, special access hatches, and so forth, might be shown on the Canvas Scan as that would affect what sort of ceiling might be the best choice. Unfortunately, the ceiling component of the scan was completely featureless. This is a typical metal framed ceiling with acoustical tiles, so it is not completely featureless, and I know from other supplied drawings that there are HVAC ducts in several areas.

Thinking that the people at Colgate had omitted to scan the ceiling, I asked them to do another round of scanning, and a few days later I received another CAD file. It was no different however in respect to the ceiling - a blank sheet. I asked the IT person at Colgate if he could talk to the people at Canvas and ask them why this info was missing from the scan. I mean, either it scanned or did not, which would show in the raw data from the scan, and if it did show in the raw data, then why were they choosing to not detail that part in the converted file?

Canvas’s site explains that:
Your CAD file will be an architectural “shell” of the space captured. Doors, walls, ceilings, floors, countertops, cabinets, and other “built-in” features will all be included, but no movable objects like furniture and decor. 
Emphasis mine.

That statement turns out to be misleading, at least in terms of ceilings. And when Colgate’s IT person tried contacting the company with questions about the scan, all they did was refer him to their FAQ page.

It’s like a lot of tech companies these days. They love to sell you a product but if you require any help afterwards, they either outsource the tech support to India, etc., or they just provide a FAQ page. Forget actually providing customer service, someone with whom you can have a conversation. I guess that costs too much. Grr..

Anyway, eventually the idea to employ ceilings was dropped due to budget constraints, so that aspect became less concerning. In the past several days, having received a drawing deposit from the University, I’ve been busy sketching.

Everything has been rolling along fairly smoothly, however yesterday I noticed some curious things.

First here is the room at one end, which will be the Chinese-themed room. This is a view down the hallway to that room:

Notice the window with the heater below? Note their relative sizes to one another - the window being narrower.

This however is how the window and heater actually look:

Clearly the heater is in fact narrower than the window. Why is the electrical box next to the heater missing from the scan? Notice also that the top of the window opening is a couple of inches below the ceiling, and a roll-up blind is placed in the junction. The scan however shows the window going right up to the ceiling.

Worse yet, the scanned window dimensions do not match the directly-obtained dimensions I had from Colgate. The window actually measures 53.875" wide, but the scan has the window at 52.36". That’s not a tiny difference and would be outside the range of error one might anticipate from a person taking measurements with a tape measure. Is it within the company’s stated “1~2%” range of error? no, it isn’t, the difference between the numbers is close to 5% off.

Then there is this curious anomaly on the scan, as we look from the window ledge back into the room itself, we can see that the window trim piece sticks up in the air:

At first I thought I must have accidentally grabbed it with the mouse and pulled it up, however re-checking the original file they sent, as well as the second scanned and converted file, revealed that both showed the window trim the same way. Not sure what is going on there. Notice also in the background how it shows the baseboard. It measures, in the sketch, as 0.5" thick and 4" tall, however the actual baseboard is not wood but glued-on vinyl, which is about half that thickness at best.

It gets worse. The sketches I had from Colgate indicated that the hallway was 59" wide, however the scan from Canvas showed a hallway that was 55.1186" wide. Such an accurate number, but very different than what was indicated on Colgate’s materials. Again, I checked both scans to see if one of them showed something different, but no. Then I contacted the Architectural Trades Manager at Colgate and had him go and double check the measure for the width of the hallway, which again came back at 59". So the scan was giving a number which was nearly 7% out from actual. That’s terrible!

I am now completely disillusioned with this product. It doesn’t perform as advertised and cannot be relied upon. I feel bad that Colgate purchased the device upon my request, given the results. While I will be able to navigate the design phase okay, when it comes time to fabricate I will need to drive out there and take measurements and double check everything.

I’d like to think in time that there will be an effective and highly accurate room scanning technology available (well, Leica has a great looking product, but at $8300 it is pricy), but with Canvas IO, the marketing promise far exceeds the actual performance. If you are just doing interior-designy stuff, where accuracy is relatively unimportant and you’re concerned with wall colors and how a particular piece of furniture might look in a space, etc., it would be fine I guess, but if the idea is to take the scan and design accurate components from it you would be heading for a world of hurt and pain.

All for this round. Thanks for visiting.
