Antonios of Sardis

Saint Antonios was bishop of Sardis in Asia Minor. He is a little-⁠known saint. His commemoration is kept together with the martyr Lupus on 25 February, according to the Greek source, and according to the Serbian source on 23 August (5 September).

The Greek source says that he lived in the eighth century. The Serbian source places him in the time of Patriarch Nicholas Mystikos (912 to 925), with whom he exchanged letters that have survived. The two dates do not agree, so his century remains uncertain.

He is mentioned in the Sinai Menaion no. 631 (of the tenth or eleventh century), where he has a canon in common with the holy martyr Lupus. No other news of his life has been preserved.
