History of the Peloponnesian War

The Lacedaemonians, however, acceded with a very decided preference to the application of the Chians and Tissaphernes. For Alcibiades was also co-operating with them, being the hereditary and very intimate friend of Endius, one of the ephors; for which reason also his family had a Lacedaemonian name, in consequence of this friendship; [*]( That is, Alcibiades was the distinguishing family name of this Endius, borne by the members of his house in every alternate generation; so that Alcibiades was the surname to every Endius, and Endius the surname to every Alcibiades. —Arnold.)
