Leontios of Neapolis

Leontios (Greek: Λεόντιος Νεαπόλεως) was Bishop of Neapolis (Limassol) in Cyprus in the 7th century CE. Works: Life of St. John the Merciful, commissioned by the archbishop of Constantia Arcadius, Life of Simeon the Holy Fool, a lost "Life of Spyridon" and an apologia against Jews. His works are considered among the few works giving any insight into the vernacular Greek of Early and Middle Byzantium.

He was probably present at the Lateran council in Rome in 649.
