Epiphany is a Greek Orthodox Religious celebration (associated with the Baptism of Christ). In Hydra and Kamini parts of the church services include the Great Blessing of Waters at both Hydra and Kamini harbours. The priests cast a cross into the sea to bless it and youngsters compete for the honour of retrieving the cross from the freezing water. The winner receives a prized blessing for the year.
The Greek Orthodox Churches perform the Great Blessing of Waters on the 6th January. The blessing is normally done twice: once on the Eve of the Feast, usually at a Baptismal font inside the church and then again on the day of the feast, outdoors at a body of 'living water', which in Hydra, is the sea at both Hydra harbour and Kamini harbour.
