Victorius.
Victorius 2729 the Aquitanian, a careful 2730 reckoner, on invitation of St. Hilary bishop of Rome, composed a Paschal cycle with the most careful investigation following his four predecessors, that is Hippolytus, Eusebius, Theophilus and Prosper, and extended the series of years to the year five hundred and thirty-two, reckoning in such wise that in the year 533 the paschal festival should take place again on the same month and day and the same moon as on that first year when the Passion and resurrection of our Lord took place.
