Amelius, Peter an Augustine monk of the 14th century, afterwards bishop of Sinigaglia. He was both at Aleth (Alecta), in Languedoc, and not at St. Malo, as some assert. He accompanied Gregory XI to Rome when that pope transported the papal throne thither from Avignon in 1376; and he wrote an account of the journey, which Papyrius Masson mentions. Amelius also wrote a Treatise of the Ceremonies of the Roman Church, published by Mabillon in vol. 2 of the Museum Italicum. See Mordri, ed. of 1759.
