[Footnote 14: 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.]
