Doric order

1. The first and simplest of the three Greek orders and the only one that normally has no base.
2. One of the three orders or organisational systems of Ancient Greek or classical architecture characterised by columns which stood on the flat pavement of a temple without a base, their vertical shafts fluted with parallel concave grooves topped by a smooth capital that flared from the column to meet a square abacus at the intersection with the horizontal beam that they carried.
