Holy Great Martyr Euphemia was Christian by birth; she suffered in 304 in Chalcedon, on the banks of Bosphorus opposite Constantinople. The governor ordered everyone to sacrifice to Mars; 49 Christians hid, praying. They were found and tortured for 19 days, after which Euphemia was taken from them - she was the youngest and they thought she would give in. God helped her overcome torture; she died in the arena when a bear bruised her leg; other animals didn't touch her. Celebrated Sept 16.
