On the 22st of May, the Hellenic Plynteria festival is observed.
The Plynteria is a festival in which the statue of Athena Polias who guards Athens is cleansed.
Women of the household of the Praxiergidai (the Athenian family tasked with the care of the statue of Athena Polias) would take the image and remove the robes, jewelry, then wrap it for a formal procession to the sea at Phaleron, where it was purified by sea water. At sundown the statue was taken by a torch lit formal procession back to the temple and re-adorned with clean robes and jewelry.
This is considered an importune time and considered quite unlucky so Athena’s temple was closed and so its a good time to clean and revamp Athena’s shrines/altars/tools.
Offer figs or cakes containing figs to Athena.
