Horsiesius

Venerable Horsiesius was an Egyptian monk of the fourth century who led the Pachomian monasteries from 346 to 350, and again from 368 to 387. He was a disciple of Saint Pachomius the Great. Before the death of Pachomius he was superior of the Sheneset monastery. After the repose of Pachomius, Petronius appointed Horsiesius superior of the Koinonia; in 350 he resigned and Theodorus of Tabennese took his place. When Theodorus died in 368, Horsiesius again became head of the community and remained so until his death in 387 or somewhat later.

His best-⁠known work is the Testament of Horsiesius, which Blessed Jerome translated into Latin in 404 (Liber Horsiesii). In Coptic, seven catecheses and four letters are also attributed to him. He is canonized as a saint by the Coptic Orthodox Church.
