Leontios
Martyr, Λεόντιος
The Holy Martyr Leontios was a soldier of Greek descent who suffered for Christ at Tripoli in Phoenicia in the early centuries of the Church. A man of courage and charity, he confessed the Lord before his accusers, and tradition tells that his steadfastness under torment brought even those sent against him to faith in Christ, so that they shared his martyrdom.

Venerable, Λεόντιος ο Αθωνίτης ο Μυροβλήτης
Saint Leontius came from Argos and became a monk of the monastery of Dionysiou on Mount Athos, where tradition relates that he lived for sixty years without ever leaving the monastery. He was granted the gift of foresight, and after his repose in 1605 his relics flowed with myrrh.

Martyr, Αιθέριος
