How did the Panathenaic procession honour Athena?

The Panathenaic procession was a central event of the Panathenaea, an ancient Athenian festival held to honor Athena, the city's protectress. The procession served as a public act of devotion and civic unity, during which the people marched to the Acropolis to present a new, embroidered peplos—a traditional garment—to the goddess.12

This grand event, which is famously depicted on the Parthenon frieze, involved various segments of Athenian society, including officials, young men on horseback, and citizens. In addition to the presentation of the robe, the festival honored Athena through the sacrifice of animals, as well as through athletic, musical, and equestrian contests. By gathering representatives from across the Athenian dependencies to participate in these rites, the procession reinforced the city's religious and political identity under the patronage of Athena.312
