Martyr in fourth-century Egypt. Mui is known only by some fragments of an Encomium in his honor, by an unknown author, published by W. E. Crum. The fragments report some miracles performed by him when he was in prison in Alexandria, his confrontation with the prefect in the lawcourt, and the tortures inflicted upon him. The beginning and the part dealing with the martyrdom are missing.
