Note 014
Both Nicephorus and Theophanes agree that the siege of Constantinople was raised the 15th of August, (A.D. 718;) but as the former, our best witness, affirms that it continued thirteen months, the latter must be mistaken in supposing that it began on the same day of the preceding year. I do not find that Pagi has remarked this inconsistency.]
