From there he went to Cyzicus and the Propontis, giving lectures; afterwards he came to the court of Mausolus. Then at length he returned to Athens, bringing with him a great number of pupils: according to some, this was for the purpose of annoying Plato, who had originally passed him over.The suggestion of hostile relations is held to be without foundation both by Tannery, Astronomie ancienne, p. 296, note 4, and T. L. Heath, Aristarchus, p. 192.
