No ancient source indicates when the agōnothesia, attested for the first time in 307/6 BC, was introduced in Athens. Scholars have long attributed its creation, along with the abolition of the liturgical chorēgia, to the government of Demetrius of Phalerum (317–307 BC), motivated by oligarchic ideology and a desire to preserve the wealth of rich citizens. This traditional thesis has recently been challenged, with some scholars attributing the creation of the agōnothesia to the restored democratic government of 307 BC and others to the government of Phocion (322–318 BC). A new look at epigraphical and literary documents hitherto neglected or imperfectly understood (especially from the Attic demes) allows the authors to establish that the liturgical chorēgia disappeared at the beginning of the government of Demetrius of Phalerum, around 316 BC. The institution of the agōnothesia had a precedent (hitherto overlooked) in Lycurgan Athens with the new festival of the Amphiaraia of 331 BC. Both measures were in fact consensual and must not be interpreted as strictly oligarchic in inspiration. The creation of the agōnothesia was above all a pragmatic response on Athens’ part to the major changes that occurred in the agonistic world in the late fourth century.
