74 EARLY GEOGRAPHICAL SPECULATIONS. [CHAP. IV. Caspapyrus or Caspatyrus, the town on the banks of the Indus from which Scylax of Caryanda was reputed to have started at the command of Darius on his voyage of exploration down that river. Several places are also noticed in Phoenicia, Syria and Arabia, and especially in Egypt, as we might expect from his having himself visited that country. The Nile was for him the boundary of Libya on its eastern side, and, as 'we have Africa' already seen, he regarded that river as flowing from the southern ocean; akin to which primitive view is his reckoning such mythical peoples as the Pygmies and the Sciapodes among the inhabitants. The remainder of the treatise, to judge from the extracts, dealt with the Mediterranean coast of Africa as far as the Straits; and even beyond that limit occurs the name of Thinge, the modern Tangier.
