Diogenes Laertius Vitae philosophorum 10.1.23

[23] His goodness was proved in all ways, as Epicurus testifies in the introductions ¹ to his works and in the third book of the Timocrates. Such he was: he gave his sister Batis to Idomeneus to wife, and himself took Leontion the Athenian courtesan as his concubine. He showed dauntless courage in meeting troubles and death, as Epicurus declares in the first book of his memoir. He died, we learn, seven years before Epicurus in his fiftythird year, and Epicurus himself in his will already cited clearly speaks of him as departed, and enjoins upon his executors to make provision for Metrodorus’s children. The above-mentioned Timocrates ² also, the brother of Metrodorus and a giddy fellow, was another of his pupils.
