Leo

Holy Martyr Leo is one of the martyrs Isidore, Leo and Acepsimas, whose time and place of martyrdom are unknown. The life of the saints has not been preserved, and their commemoration appears in the calendars twice. On 4 October it is found in the Typikon of the Great Church, in the Synaxarion of the church of Constantinople (with the clarification in Greek "in the rivers") and in some other calendars and menaia. On 7 December the commemoration of Isidore, Leo and Acepsimas and a couplet dedicated to them are found in the Greek verse synaxaria (State Historical Museum, Greek Syn. no. 390 (354), of 1295), in the printed Greek Menaion (Venice, 1595) and in the "Synaxaristes" of the Venerable Nicodemus the Hagiorite. They say that the martyrs died in fire.

Saint Leo is commemorated on 7/20 December, according to the Greek calendar. His name is not in the present calendar of the Russian Orthodox Church.
