Agatharchides, of Cnidus, Greek historian, geographer, and Peripatetic philosopher, c. 215–after 145 BCE

Who lived most of his adult life in *Alexandria (1), eventually leaving, perhaps in flight to Athens after 145. He was not, as previously believed, regent to *Ptolemy (1) IX but was in the service of *Heraclides (3) Lembus. His major works, for which there are fragmentary remains, include: Asian Affairs (Τὰ κατὰ τὴν Ἀσίαν), probably a universal history that extended to the *Diadochi; European Affairs (Τὰ κατὰ τὴν Εὐρώπην), perhaps to his own time; and On the Red Sea (Περὶ τῆς Ἐρυθρᾶς θαλάσσης) in five books (some preserved by Diodorus, bk. 3, and Photius). These large-scale histories, interlaced with *anthropology and *geography, provided a model for *Posidonius (2). He attacked the Asianic prose style, and *Photius calls him a worthy disciple of *Thucydides (2) in expression. He may have voiced hostility toward the Ptolemies, from whom he may have fled.
