2. The brother of Jason of Pherae, Tagus of Thessaly, obtained the supreme power along with his brother Polyphron, on the death of Jason in B. C. 370.
But shortly afterwards as the two brothers were on a journey to Larissa, Polydorus died suddenly in the night, assassinated, as it was supposed, by Polyphron (Xen. Hell. 6.4.33
). Diodorus makes a mistake in stating (15.61) that Polydorus was killed by another brother Alexander, who afterwards became tyrant of Pherae; for this Alexander was the nephew, and not the brother of Polydorus and Polyphron. (Plut. Pel. 100.29
.) [See Vol. I. p. 124.]
