Strabo Geography 17.1.35

[35] Next to Memphis is the city Acanthus, situated also in Libya, and the temple of Osiris, and the grove of the Thebaïc acantha, from which gum is procured. Next is the Aphroditopolite Nome, and the city in Arabia of the same name, where is kept a white cow, considered sacred. Then follows the Heracleote Nome, in a large island, near which is the canal on the right hand, which leads into Libya, in the direction of the Arsinoïte Nome; so that the canal has two entrances, a part of the island on one side being interposed between them. ¹ This nome is the most considerable of all in appearance, natural properties, and embellishment. It is the only nome planted with large, full-grown olive trees, which bear fine fruit. If the produce were carefully collected, good oil might be obtained; but this care is neglected, and although a large quantity of oil is obtained, yet it has a disagreeable smell. (The rest of Egypt is without the olive tree, except the gardens near Alexandreia, which are planted with olive trees, but do not furnish any oil.) It produces wine in abundance, corn, pulse, and a great variety of other grains. It has also the remarkable lake Moeris, which in extent is a sea, and the colour of its waters resembles that of the sea. Its borders also are like the sea-shore, so that we may make the same suppositions respecting these as about the country near Ammon. For they are not very far distant from one another and from Paraetonium; and we may conjecture from a multitude of proofs, that as the temple of Ammon was once situated upon the sea, so this tract of country also bordered on the sea at some former period. But Lower Egypt and the country as far as the Lake Sirbonis were sea, and confluent perhaps with the Red Sea at Heroopolis, and the Aelanitic recess of the gulf.
