SCYLAX, a celebrated mathematician and geographer in the isle of Ceryanda, in Caria, flourished under the reign of Darius Hytaspes, about 522 B. C. Some have attributed to him the invention of geographical tables. We have under his name a geographical work published by Hoechelius; but it is written by a much latter author, and is perhaps only an abridgement of Scylax's Ancient Geography.
