 The capital was very much deeper than either the Doric or the Ionic capital, being shaped like a large "krater", a bell-shaped mixing bowl, and being ornamented with a double row of acanthus leaves above which rose voluted tendrils, supporting the corners of the abacus, which, no longer perfectly square, splayed above them.According to Vitruvius, the capital was invented by a bronze founder, Callimachus of Corinth, who took his inspiration from a basket of offerings that had been placed on a grave, with a flat tile on top to protect the goods.The basket had been placed on the root of an acanthus plant which had grown up around it.
