Corinthian order : kaw-RIN-thee-un

(Most elaborate of the Greek architectural styles and least used by the Greeks). Resembles Ionic in most aspects except for the column capital; Corinthian columns have tall capitals shaped like upside-down bells and are covered with rows of acanthus leaves and small vine-like spirals called helixes. The Corinthian order was originally used for columns inside buildings and did not appear externally until the 4th century BC; use in exterior temple colonnades did not become widespread until Roman times.
