Athens held the Panathenaia, a festival where a peplos was presented to Athena. The festival honored Athena Polias, the city’s patron deity, and was the most important civic celebration in ancient Athens.
A peplos is a traditional Greek garment, usually a long woolen robe. In the Great Panathenaia, Athenians presented a specially woven peplos to the statue of Athena. The procession and offering connected religious worship, textile skill, citizenship, and the identity of the city.
This detail relates to Pandora because Athena’s contribution to Pandora’s creation is traditionally connected with clothing and weaving. The Panathenaia is not a Pandora festival, and the peplos was made for Athena rather than Pandora. The neighboring facts belong to the wider Greek religious and artistic context surrounding the myth.
