Strabo Geography 2.5.25

[25] To speak shortly, the southernmost point of Our Sea is the recess of the Greater Syrtes; ¹ next to this Alexandria in Egypt, and the mouths of the Nile; while the most northerly is the mouth of the Dnieper, or if the Maeotis be considered to belong to the Euxine, (and it certainly does appear to form a part of it,) the mouth of the Don. The Strait at the Pillars is the most westerly point, and the most easterly is the said recess, in which Dioscurias ² is situated; and not, as Eratosthenes falsely states, the Gulf of Issus, ³ which is under the same meridian as Amisus ⁴ and Themiscyra, and, if you will have it so, Sidene as far as Pharnacia. ⁵ Proceeding thence in an easterly direction to Dioscurias, the distance by sea is above 3000 stadia, as will be seen more plainly in my detailed account of those countries. Such then is the Mediterranean.
