Note 99
From Chapter 53 of the Decline & Fall

Abulpharagius assigns the 7th Dynasty to the Franks or Romans, the 8th to the Greeks, the 9th to the Arabs.

A tempore Augusti Cæsaris donec imperaret Tiberius Cæsar spatio circiter annorum 600 fuerunt Imperatores C. P. Patricii, et præcipua pars exercitûs Romani: extra quod, consiliarii, scribæ et populus, omnes Græci fuerunt: deinde regnum etiam Græcanicum factum est (p. 96, vers. Pocock).

The Christian and ecclesiastical studies of Abulpharagius gave him some advantage over the more ignorant Moslems.
