But by the industry of Eusebius, who took his surname from the blessed martyr Pamphilus, it was reduced to a plainer system; insomuch that what till then used to be sent about to all the several churches by the patriarch of Alexandria, might, from that time forward, be most easily known by all men, the course of the fourteenth day of the moon being regularly ordered.
