According to custom, I give you notice respecting Easter, my beloved, that you also may notify the same to the districts of those who are at a distance, as is usual. Therefore, after this present festival 4435 , I mean this which is on the twentieth of the month Pharmuthi, the Easter-day following will be on the vii Id. April, or according to the Alexandrians on the twelfth of Pharmuthi. Give notice therefore in all those districts, that Easter-day will be on the vii Id. April, or according to the Alexandrian reckoning on the twelfth of Pharmuthi. That you may be in health in Christ, I pray, my beloved brethren.
Observe that Athan. gives notice at Easter, a.d. 344, upon what day Easter is to be observed in a.d. 345, and not immediately after the succeeding Epiphany, as Cassian asserts to have been the custom of the Patriarch of Alexandria. (Cassian. Collat. x. 1.) Cf. Letters 2, 4, 10, 18, &c.
