CADMUS OF MILETUS, according to some ancient authorities, the inventor of history, or simply the author of certain letters of the Greek alphabet. Suidas mentions three writers so called, one being "later" and author of a history of Attica, among other works. He may be real; but, as Dionysius of Halicarnassus (ludicium de Thucydide, c. 23) distinctly states that the work current in his time under the name of Cadmus was a forgery, it is most probable that the two first are identical with the Phoenician Cadmus, who, as the reputed inventor of letters, was subsequently transformed into the Milesian and the author of an historical work.
