CALE or CALEM(Portoor Oporto). a city on the S. border of Gallaecia, in Spain, on the N. side of the Durius ( Douro) near its mouth; and on the high road from Olisipo to Bracara Augusta, 35 M. P. south of the latter place. (Sallust. ap. Serv. ad Virg. Aen. 7.728, reading Gallaecia for Gallia; Itin. Ant. p. 421; Florez, Esp. S. 21.5, 14.70.) It may possibly be the CALADUNUM(Καλάδουνον) of Ptolemy, the termination denoting its situation on a hill (2.6.39). Though thus barely mentioned by ancient writers, its position must early have made it a considerable port; so that it came to be called Portus Cale, whence the name of Porttgalhas been derived. The modern city O-Porto (i. e. the Port) stands a little E. of the site of Cale, which is believed to be occupied by the market town of Gaya. [P.S]
