Note 101
From The Invasion of Egypt, part of Chapter 51 of the Decline & Fall

Strabo, an accurate and attentive spectator, observes of Heliopolis,
(Geograph. l. xvii. p. 1158); but of Memphis he declares,
(p. 1161); however, the mixture of inhabitants, and the ruin of the palaces. In the proper Egypt, Ammianus enumerates Memphis among the four cities, maximis urbibus quibus provincia nitet (xxii. 16.); and the name of Memphis appears with distinction in the Roman Itinerary and episcopal lists.
