Pyanepsia was celebrated in Athens during the month of Pyanepsion, chiefly in honor of Apollo. Participants prepared a porridge of beans and grains, while children carried an eiresione, a decorated olive branch hung with fruit, wool, and household offerings. The ceremony commemorated Theseus's return from Crete and his vow to Apollo. In poetry, the festival offers images of hunger transformed into gratitude, branches speaking through gifts, and communal memory carried from door to door.
