[705] The Troglodytica extended along the western side of the Arabian Gulf, from about the 19th degree of latitude to beyond the strait. According to Pliny, vi. c. 34, Sesostris conducted his army as far as the promontory Mossylicus, which I think is Cape Mète of the modern kingdom of Adel. _Gossellin._ [706] The 60 and 200 stadia assigned to the straits refer to the two passages there to be found. The 60 stadia agree with the distance of the eastern cape of Bab-el-Mandeb, the ancient Palindromos, to the island Mehun; and the 200 stadia to the distance of this island from the coast of Africa. In this last interval are the six islands of which Strabo speaks. [707] This passage has sometimes been mistaken to mean, that the region producing myrrh and cinnamon refers to the southern coast of Arabia. Our author here speaks of the coast of Africa, which extends from the Strait of Bab-el-Mandeb to Cape Guardafui. This space in following the coast is 160 or 165 leagues, which are equivalent to 5000 olympic stadia. _Gossellin._ [708] The long and interesting passage from § 5 to the end of § 20 is taken from Artemidorus, with the exception of a very few facts, which our author has taken from other sources, accompanied by observations of his own. On comparing this fragment of Artemidorus with the extracts of Agatharchides preserved by Photius, and the description of Arabia and Troglodytica which Diodorus Siculus (b. iii. 31) says he derived from Agatharchides, we find an identity, not only in almost all the details, but also in a great number of the expressions. It is, therefore, evident that Artemidorus, for this part of his work, scarcely did anything more than copy Agatharchides. Agatharchides, in his youth, held the situation of secretary or reader to Heraclides Lembus, who (according to Suidas) lived in the reign of Ptolemy Philometor. This king died B. C. 146. He wrote a work on Asia in 10 books, and one on Europe in 49 books; a geographical work on the Erythræan Sea in 5 books; a treatise on the Troglodytæ in 5 books; and other works. He wrote in the Attic dialect. His style, according to Photius, was dignified and perspicuous, and abounded in sententious passages, which inspired a favourable opinion of his judgment. In the composition of his speeches he was an imitator of Thucydides, whom he equalled in dignity, and excelled in clearness. His rhetorical talents also are highly praised by Photius. He was acquainted with the language of the Ethiopians, and appears to have been the first who discovered the true cause of the inundations of the Nile. See Smith, art. Agatharchides. [709] Ghela.
