Festivals

Various religious festivals were held in ancient Greece. Many were specific only to a particular deity or city-state. For example, the festival of Lykaia was celebrated in Arcadia in Greece, which was dedicated to the pastoral god Pan. Like the other Panhellenic Games, the ancient Olympic Games were a religious festival, held at the sanctuary of Zeus at Olympia. Other festivals centered on Greek theatre, of which the Dionysia in Athens was the most important. More typical festivals featured a procession, large sacrifices and a feast to eat the offerings, and many included entertainments and customs such as visiting friends, wearing fancy dress and unusual behavior in the streets, sometimes risky for bystanders in various ways. Altogether the year in Athens included some 140 days that were religious festivals of some sort, though they varied greatly in importance.
