By this reckoning, then, the seaboard of Egypt [30,27] (nation), Africa Egypt will be four hundred and fifty miles in length. Inland from the sea as far as Heliopolis [31.333,30.1] (deserted settlement), Cairo, Urban, Egypt, Africa Heliopolis, Egypt [30,27] (nation), Africa Egypt is a wide land, all flat and watery and marshy. From the sea up to Heliopolis [31.333,30.1] (deserted settlement), Cairo, Urban, Egypt, Africa Heliopolis is a journey about as long as the way from the altar of the twelve gods at Athens [23.7333,37.9667] (Perseus)Athens to the temple of Olympian Zeus at Pisa [21.65,37.65] (Perseus)Pisa.

If a reckoning is made, only a little difference of length, not more than two miles, will be found between these two journeys; for the journey from Athens [23.7333,37.9667] (Perseus)Athens to Pisa [21.65,37.65] (Perseus) Pisa is two miles short of two hundred, which is the number of miles between the sea and Heliopolis [31.333,30.1] (deserted settlement), Cairo, Urban, Egypt, Africa Heliopolis.
