Pierius.

        There are even fewer fragments from the works of his successor Pierius, who taught at Alexandria during the last decades of the third century and wrote not only theological treatises (including one on “the God-bearer” or “Mother of God”) but also exegetical works on books of the Old and New Testaments. According to Philip of Side (fifth century) both Pierius and his brother Isidore were martyrs and a large church was built at Alexandria in their memory. The martyrdom must have occurred after 309, when Pamphilus was put to death, for Philip says that Pierius wrote a treatise on his life. Jerome says that “after the persecution” Pierius lived in Rome, and it may be that the martyrdom involved confession but not death.
