St Pontain was the 18th Pope from 230 to 235. He was the third of four Popes who were opposed by Hippolytus as the anti Pope in a schism of the church. Little is known of his accomplishments. Persecution of Christians resumed in 235 when Emperor Maximinus the Thracian started his reign. Both Pope Pontain and Hippolytus were arrested and exiled to the mines of Sardinia. Pontain resigned as bishop so a successor could be named. He died at Sardinia in October 235. His Feast day is celebrated on August 13.
