Apollonius of Acharnae

Apollonius of Acharnae (Ancient Greek: Άπολλώνιος) was a heortologist and writer of ancient Greece who lived in the late 2nd century BCE.^[1][2] He was the author of a work on the festivals, On the Festivals (Περὶ ἑορτῶν).^[3][4]

Modern scholars have a dubious opinion of some of the assertions of Apollonius that have been handed down to us -- namely that the Diasia and Meilichios were two separate and distinct festivals.^[2][5][6]
