Note 22 — Ecclesiastical Survey of the Philippines
Reading edition
St. Cassian was a native of Imola, Italy, who was martyred under one of the Roman emperors (Decius, Julian the Apostate, or Valerian). He was a schoolmaster of little children whom he taught to read and write, and his pupils denounced him as a Christian. He was delivered over to his former charges, and they wreaked their vengeance on him by breaking their tablets over his head and piercing him with their styluses. His feast is celebrated on August 13.—T. C. Middleton, O.S.A.
