p.59: "Critobulus." Wikipedia says that "Xenophon depicts Socrates as chastising the supposedly otherwise moderate Critobulus for kissing "the beautiful son of Alcibiades" (Memorabilia 1.3.8-10; cf. his Symposium 4.23-26)." Also  Critobulus was the son of Criton, and a disciple of Socrates. He did not however profit much by his master's instructions, if we may trust the testimony of Aeschines the Socratic by whom he is represented as destitute of refinement and sordid in his mode of living.
