John Bostock translation
The Mareotis of the time of the Ptolemies extended from Alexandria to the Gulf of Plinthinethes; and Libya was properly that portion of territory which extended from that Gulf to Catabathmos. Pliny is in error here in confounding the two appellations, or rather, blending them into one. It includes the eastern portion of the modern Barca, and the western division of Lower Egypt. It most probably received its name from the Lake Mareotis, and not the lake from it.
