AUGUSTALIS the African. The first ecclesiastical author to leave an aid for the computation of Easter was Augustalis. He composed a Laterculus, i.e. an Easter table, giving the date for the celebration of Easter from 213 312. He used an 84-year Easter cycle; the custom of indicating on every 1 January the age of the moon Epact and the day of the week perhaps goes back to him.
He also proposed the saltus lunae every 14 years. His work is lost, but its basic instructions can be deduced from information in the anonymous Computus Carthaginensis, a.455, written in the 16th year of King Genseric CPL 2296; see B.
Krusch, Studien zur christlich-mittelalterlichen Chronologie, I, 279-297. Since he was eulogized as sanctissimae memoriae I, 8, he was probably bishop of an African see; he is also called litterarum scientia praeditus et calculationis arte peritus. Augustalis's cycle, widely used in Africa until the late 4th c., was continued and revised by Agriustia; the church of Rome must also have used it until the end of the 3rd c.
