Eutirtio Augustinus, 17th century, Italian virtuoso singer, Franciscan friar. He belonged to the court ensemble of Władysław IV Vasa; his presence there is attested in the years 1643–46, but he probably worked there earlier, while in 1650 he does not appear on the ensemble’s list. M. Scacchi included his three-voice canon in Cribrum musicum (1643).
