" Glaucon, (1) the son of Ariston, had conceived such an ardour to gain the headship of the state that nothing could hinder him but he must deliver a course of public speeches, (2) though he had not yet reached the age of twenty. His friends and relatives tried in vain to stop him making himself ridiculous and being dragged down from the bema. (3) Socrates, who took a kindly interest in the youth for the sake of Charmides (4) the son of Glaucon, and of Plato, alone succeeded in restraining him.

(1) Glaucon, Plato's brother. Grote, "Plato," i. 508.

(2) "Harangue the People."

(3) See Plat. "Protag." 319 C: "And if some person offers to give them
advice who is not supposed by them to have any skill in the art
(sc. of politics), even though he be good-looking, and rich, and
noble, they will not listen to him, but laugh at him, and hoot
him, until he is either clamoured down and retires of himself; or
if he persists, he is dragged away or put out by the constables at
the command of the prytanes" (Jowett). Cf. Aristoph. "Knights,"
665, {kath eilkon auton oi prutaneis kai toxotai}.

(4) For Charmides (maternal uncle of Plato and Glaucon, cousin of
Critias) see ch. vii. below; Plato the philosopher, Glaucon's
brother, see Cobet, "Pros. Xen." p. 28. "
