Holy New Martyr Agathangelos of the Esphigmenou Monastery, beheaded at Smyrna.
Agathangelos was born Athanasios in Thrace and, working as a sailor, was pressed into accepting Islam by the Turks. Repenting, he fled to Mount Athos and became a monk at Esphigmenou, where he prepared himself to confess the faith he had denied.
He returned to Smyrna, publicly declared himself a Christian, and was beheaded there in 1819.
