Quadratus of Corinth was born on a mountain near Corinth, where his mother had fled to escape a persecution, during the third century, against Christians. He was a hermit and healer. During the Decian persecution, unable to persuade Quadratus and his friends Cyprian, Dionysius, Anectus, Paul and Crescens to deny Christ, the military prefect ordered the martyrs to be thrown to wild beasts, but the beasts did not touch them. They were then beheaded with a sword.[4] They are commemorated on 10 March.[5][6][3]
