In their original Greek version, Doric columns stood directly on the flat pavement (the stylobate) of a temple without a base. With a height only four to eight times their diameter, the columns were the most squat of all the classical orders; their vertical shafts were fluted with 20 parallel concave grooves; and they were topped by a smooth capital that flared from the column to meet a square abacus at the intersection with the horizontal beam (architrave) that they carried. The Parthenon has the Doric design columns. It was most popular in the Archaic Period (750-480 BC) in mainland Greece, and also found in Magna Graecia (southern Italy), as in the three temples at Paestum. These are in the Archaic Doric, where the capitals spread wide from the column compared to later Classical forms, as exemplified in the Parthenon.
