I want to know the answer to the following question:
About whom did he write his most widely-read work?
All the background I'm provided with is that "His biography of Anthony the Great entitled Life of Antony(Βίος καὶ Πολιτεία Πατρὸς Ἀντωνίου, Vita Antonii) became his most widely-read work.". Is that enough to answer the question?
