From their commentaries I have gathered what I saw was useful for the present subject, and formed it into one complete treatise, and this principally, because I saw that many books in this field had been published by the Greeks, but very few indeed by our countrymen. Fuficius, in fact, was the first to undertake to publish a book on this subject. Terentius Varro, also, in his work "On the Nine Sciences" has one book on architecture, and Publius Septimius, two.
15. But to this day nobody else seems to have bent his energies to this branch of literature, although there have been, even among our fellow-citizens in old times, great architects who could also have written with elegance. For instance, in Athens, the architects Antistates, Callaeschrus, Antimachides, and Pormus laid the foundations when Peisistratus began the temple of Olympian Jove, but after his death they abandoned the undertaking, on account of political troubles. Hence it was that when, about four hundred years later, King Antiochus promised to pay the expenses of that work, the huge cella, the surrounding columns in dipteral arrangement, and the architraves and other orna-
