Choragic Monument of Thrasyllos

The Choragic Monument of Thrasyllos is a memorial building erected in 320–319 BCE on the artificial scarp of the south face of the Acropolis of Athens to commemorate the choregos, Thrasyllos. It is built in the form of a small temple and fills the opening of a large, natural cave. It was modified in 271–270 BCE by Thrasykles the son of Thrasyllos, agonothetes in the Great Dionysia Games.

Pausanias refers to the monument indirectly, providing us with the information that in the cave there existed a representation of Apollo and Artemis slaughtering the children of Niobe. Echoing the west part of the south wing of the Propylaea, the facade of the monument is formed by two monumental doorways with antae and a central pillar, door frames, architrave with continuous guttae, frieze and cornice.

The frieze was decorated with ten olive wreaths, five on each side of a central wreath, while the cornice supported bases for the choragic tripods. It was built in a variety of marbles from local quarries. On the epistyle there was the inscription: Thrasyllos, son of Thrasyllos of Dekeleia, set this up, being choregos and winning in the men's chorus for the tribe of Hippothontis. Euios of Chalkis played the flute.

Neaichmos was archon. Karidamos son of Sotios directed. Two subsequent inscriptions were added in the years 270–271 BCE, which read: The demos was choregos. Pytharatos was archon.
