Ten Martyrs of Crete
Martyr, Δέκα Μάρτυρες Κρήτης
The Ten Holy Martyrs of Crete suffered together under the persecution of the emperor Decius in the third century. Drawn from various towns of the island, they were brought before the governor at Gortyna, and when they refused to sacrifice to the idols they endured mockery and torments for many days before being beheaded, going to their death rejoicing.
Nahum of Ochrid

Cyril and Methodius and a fellow-labourer of St. Clement of Ochrid in the enlightenment of the Slavs. He founded the monastery on the southern shore of Lake Ochrid that bears his name, where he reposed in peace in the early tenth century. His relics are venerated there as a source of healing.
