Leo

Saint Leo the Martyr is commemorated on 1 March (new style, the calendar of the Church of Greece) together with his brother Gervasius, among the martyrs of the day. The Greek calendar lists them as brothers by blood; the English calendar remembers on the same day the brothers Gervasius and Leo, around the year 900, but it cannot be said with certainty that it is the same pair.

The sources consulted give no other details about his life, nor about the place or time of his suffering.
