• The custom of Klidonas revived the feast of St. John the Fotaras (June 24) at Ysternia.
  • The first descriptions of this custom come from the Byzantine period.
  • A few days before the event, every resident would place an object in the "Klidona" which was locked on the eve of the celebration.
  • On the day of the feast, the villagers would gather and unlock it.
  • One by one, they get an object from Klidonas but in order to take back what belongs to them, they should recite verses to the one holding it.
  • A feast follows and everybody is offered the traditional pie
  • This custom, along with its variations, is identified in many other places in Greece.
