The Choragic Monument of Lysicrates near the Acropolis of Athens was erected by the choregos Lysicrates, a wealthy patron of musical performances in the Theater of Dionysus, to commemorate the prize in the dithyramb contest of the City Dionysia in 335/334 BCE, of which performance he was liturgist. The monument is known as the first use of the Corinthian order on the exterior of a building. It has been reproduced widely in modern monuments and building elements.
