(Ἀρχέλαος), a Greek GEORGAPHER, who wrote a work in which he descsribed all the countries which Alexander the Great had traversed. (Diog. Laert.2.17.) This statment would lead us to conjecture, that Archelaus was a contemporary of Alexander, and perhaps accompanied him on his expeditions. But as the work is completely lost, nothing certain can be said about the matter. In like manner, it must remain uncertain whether this Archelaus is the same as the one whose " Euboeica" are quoted by Harpocration (s. v. Ἁλόννηδος, where however Maussac reads Archemachus), and whose works on rivers and stones are mentioned by Plutarch (de Fluv. 1 and 9) and Stobaeus. (Florileg. 1.15.)
