Plato forbids children wine till eighteen years of age, and to get drunk till forty; but, after forty, gives them leave to please themselves, and to mix a little liberally in their feasts the influence of Dionysos, that good deity who restores to younger men their gaiety and to old men their youth...fit to inspire old men with mettle to divert themselves in dancing and music; things of great use, and that they dare not attempt when sober.
