It was originally celebrated in Amarynthos, Euboea, with the participation of people from Eretria and Karystos, and later in Attica, specifically in the deme of Athmonun.
[1] During the festival, the Eretrians would form a procession from their city to the sanctuary of Amarynthian Artemis, where they would sacrifice rams.
The celebrations included musical, athletic, and dramatic competitions.
Strabo records that a pillar in that temple bore an inscription detailing that the Eretrians once conducted a festival procession comprising 3,000 hoplites, 600 cavalrymen, and 60 chariots.
Athletes from across Greece participated in the Amarysia, and the victors were awarded gold prizes.
