Abba Agathon was an Egyptian Orthodox Christian monk and saint who lived around the 4th century in Scetis, Lower Egypt and was known for his meekness and discernment.
He moved after the destruction of Scetis and lived near Troe (Τρώη / Τροία) close to the Nile with his disciple Abraham.
[1] The abba is said to have even lived for three consecutive years with a stone in his mouth to help himself learn silence and abstinence from speech.
[5] Once certain monks came to Abba Agathon to test him, falsely accusing him of being a fornicator, a speaker of nonsense, a proud man, and a heretic.
[1] Abba Agathon once admonished a brother monk for desiring to take a single discarded green pea on the roadside.
[1] Abba Agathon charged his disciples to sell their good in the market for the first price that the buyer asked for.
[1] In The Prologue of Ohrid the story is related of how a monk complimented Abba Agathon of a small knife that he used to cut brushwood.
[3] A troparion (tone 8) dedicated to Agathon: By a flood of tears you made the desert fertile, and your longing for God brought forth fruits in abundance.
