2. The father of Cadmus, tyrant of Cos, mentioned by Herodotus (7.163), is supposed by K. O. Muller (Dorians, vol. i. p. 193, note) to be identical with the preceding [CADMUS]. The subsequent removal of Cadmus to Zancle certainly gives much probability to the conjecture. Valckenaer and Larcher, however (ad Herod. 6.23, 7.163) consider him to have been another person of the same family.
