PLINTHINE(Πλινθίνη, Strab. 17. p. 799; Ptol. 4.5.8; Steph. B. s. v.), the frontier town of Aegypt towards Libya. It stood at the head of the Plinthinetic bay, in latitude 29° 40‘ N., just within the Mareotic nome, but beyond the limits of the Delta proper. There are no remains enabling us to determine the exact site of this town; but it cannot have been far from Taposiris ( Abousir), of which the ruins are still visible about 25 miles W. of Alexandreia. An inferior kind of wine was produced in this region of Aegypt; and Hellanicus ( Fr. 155) says that the people of Plinthine originally discovered the virtues of the grape. (Athen. 1. p. 34.)
