Amun was a 4th-century Christian ascetic who established one of the most prominent monastic communities in Egypt. Born in Ancient Egypt, he lived as a hermit in the Nitrian Desert, specifically in the regions of Scetis and Nitria. He is recognized for organizing individual hermits into a structured monastery at Kellia. His reputation for piety was significant enough that Athanasius of Alexandria, in his writings regarding Anthony the Great, noted his spiritual importance. He is commemorated as a saint in several Christian traditions.
