Here the builders had used the Corinthian column, with the acanthus leaves varied with fruit-designs and with the human figure. "It was a lucky day for architecture when the column came into use. It doubtless got its start from a single beam used for support. Then the notion developed of making it ornamental by fluting it and decorating the top. In this Exposition three kinds of columns are used, the Doric, which the Greeks favored, with the very simple top or capital; the Ionic, with the spiral scroll for the capital, and the Corinthian, with the acanthus flowing over the top, and the Composite which uses features from all the other three." "Do you happen to know how the acanthus design was made? Well, Vitruvius tells the story. Anyone that wants to get a line on this Exposition ought to read that book, or, at any rate, to glance through it and to read parts of it pretty thoroughly. It is called 'The Architecture of Marcus Vitruvius Pollio.' There's a good translation from the Latin by Joseph Gwilt. It has become the architect's bible. According to Vitruvius, the nurse of Corinthian girl who had died carried to the girl's tomb basket filled with the things that the girl had particularly liked. She left the basket on the ground near the tomb and covered it with a tile. It happened that it stood over the root of an acanthus plant. As the plant grew its foliage pressed up around the basket and when it reached the tile the leaves were forced to bang back in graceful curves. Callimachus, a Corinthian architect, noticed the effect and put it into use." IV Under the Tower of Jewels
