Biography

From wikipedia:

"Achillas had been ordained a presbyter by Pope Theonas of Alexandria with Pierius, and was made the head of the Catechetical School of Alexandria upon the departure of Pierius, who had either left for Rome or been made a martyr at Alexandria. He was apparently very highly thought of for his work in Greek philosophy and theological science, as Pope Athanasius the Apostolic later described him by the honorific "Achillas the Great".[1]

He came to office after the martyrdom of his predecessor, Pope Peter "Seal of the Martyrs", during the Diocletian Persecution. He inherited the troubles the church was experiencing at the time, including the Meletian heresy."

Pope from 311 to his death in 313.
