Parilia (ancient Rome)

The Parilia or Palilia was an ancient Roman festival of rural character performed annually on 21 April, aimed at cleansing both sheep and shepherd. It was carried out in acknowledgment to the Roman deity Pales, a deity of uncertain gender who was a patron of shepherds and sheep.

April 21 is the 111th day of the year in the Gregorian calendar; 254 days remain until the end of the year.
