A message from our President, Paul Gunther
There is no doubt that after the general goal of extending programmatic outreach from all of our present nodes of operation, our Beaux-Arts Atelier has emerged as our most important education priority. The inaugural class of 2012 graduates next month, following their term-ending drawing intensive in Rome; the class of 2013 is selected and will be announced to all of our constituents next month. One strategic outcome of the BAA is that its success is in turn building momentum for the overall continuing education calendar across the country, just as it is encouraging new institutional accredited partnerships about which you’ll be hearing more in coming weeks.
The foremost tactical goal in coming years is to cement the Atelier in place permanently and the best path to that vital end is the creation of scholarships. At the end of the day that’s where the action lies.
Richard Driehaus propelled us on this front with his magnificent ten-year Driehaus Scholar program. Taconic Builders stepped up next along with Alfred and Jane Ross with namesake scholarships.
More recently the Northern California Chapter has very graciously voted to create an annual chapter scholarship reserved for a deserving Atelier student hailing from their region. The opportunity now yields to recruitment for next year with the chapter’s guiding hand. Please help spread the word, as all of us here will do.
Now the Utah Chapter, via its founding president Robert Baird, has announced a scholarship beginning immediately for Class of 2013 Utah-based student, Corey Strange. Again a wonderful precedent in the Beehive State.
And the latest tuition-assistance offering, at the 31st annual Arthur Ross Awards for Excellence in the Classical Tradition that took place this past Monday in Charles Follen McKim’s masterpiece University Club, I had the distinct honor of announcing that Roy Zeluck, in memory of his late brother and spirited business partner, Kevin, has created the Marc Appleton/Roy Zeluck Scholars Program. The occasion was especially fitting as Marc was receiving the 2012 Board of Directors Honor; the announcement was thus a fitting lagniappe.
This new Appleton/Zeluck Fund consists of a $10,000 annual scholarship starting with the class of 2014, incoming next year, for an outstanding student candidate from Southern California to be recruited and recommended by a special chapter committee.
Over time, these scholars returning home will be able to teach ICAA classes based upon the unparalleled rigor of their yearlong Beaux-Arts Atelier training. The inexorable decentralization of ICAA teaching is an organic and hopeful result.
All of us are grateful to Roy and to Kevin’s surviving example and the dynamic tribute they are making in honor of their friend and partner in building, Marc Appleton. It is thrilling news.
Join me please in praising these generous pioneers.
Please know that additional tuition funds are very much needed and can be awarded charitably by name and jurisdiction, among other criteria that the donor might wish to designate. It is the essential lifeblood of our unique teaching role in confronting the cultural amnesia that threatens the very fabric of who we are as a people best unified by shared values descending from common experiences and understanding.
And so take advantage of the sophisticated array of opportunities in the weeks ahead as the Institute’s monthly calendar describes.














CLASSICAL COMMENTS: EUSTYLE

In The Ten Books on Architecture, the famous (and only surviving) ancient treatise on architecture, its author, Vitruvius, discusses how the character of a temple portico can be affected by the spacing of its columns. Vitruvius defines closely spaced columns pycnostyle, which means the column shafts are spaced one and a half column diameters apart. This gives a portico a very static appearance. The widest spacing is araeostyle, which is four diameters apart. Vitruvius tells us araeostyle is impossible with masonry construction because the spans are too great for stone architraves. Areaostyle spacing is practical only when architraves are composed of wooden beams. Other types of intercolumniation are systyle (two diameters apart) and diastyle (three diameters apart). In all four spacing types, the columns have equal-width spaces between them.
Vitruvius then informs us that the ideal intercolumniation system is eustyle. As defined by Vitruvius, a eustyle portico has bays that are two and a quarter diameters in width except for the center bay, which is three diameters wide. Vitruvius proclaimed the superior quality of eustyle spacing, stating, “In this way, the temple will have a beautiful configuration with no obstruction at the entrance.”[1] The term eustyle is derived from the Latin prefix eu, meaning good (as in euphoria—feeling good), and the Latin stilus, a narrow cylindrical object; i.e., a column shaft. The principle of eustyle spacing can be applied to porticos of four (tetrastyle), six (hexastyle), and eight (octastyle) or more columns.

In perusing Book 4 of Andrea Palladio’s Quattro Libri (Four Books on Architecture), we might note that the majority of the ancient porticoed temples in Palladio’s reconstruction drawings incorporate some form of eustyle spacing. Among them is the Pantheon, where Palladio notes that the portico’s center bay, in Vincentine feet and inches,[2] is 9’3½” wide, while the outer bays are 8’2½”wide. (Figure 2) Even though the temples Palladio measured and illustrated normally employ a slightly wider center bay, not all strictly follow Vitruvius’s spacing formula. Indeed, in some of the temple elevations, such as that for the Temple of Saturn, the dimension variation is so subtle that we need to look very carefully to see the effect. (Figure 3) Except for the Ionic temples of Portunus[3] and Saturn,[4] all of the porticoed temples Palladio included in Book 4 are in the Corinthian order, the preferred order for major buildings of the Roman imperial period.
