This letter seems to have been written shortly before Easter of the year 263; for the festal epistle to Hierax, quoted in the last chapter, was written while the war was still in progress (i.e. in 262), this one after its close. It does not seem to have been a regular festal epistle so-called, for in §11, below, we are told that Dionysius wrote a regular festal letter (ἑορταστικὴν γραφήν) to the brethren in Egypt, and that apparently in connection with this same Easter of the year 263.
