But Alcibiades, like Byron, clearly had that indefinable something. One catches a glimpse of it in the unforgettable last scene of Plato’s Symposium, when he crashes into the room, blind drunk, flirting with everything on legs, shouting about his love for Socrates. Thucydides captures it in his report of Alcibiades’s speech whipping up the Athenian assembly to vote for the disastrous Sicilian expedition of 415 BC – an extraordinary stew of egotistic bragging (about how successful his racehorses are), mendacious demagoguery and brilliantly acute strategic thinking. The unwashed Athenian masses, not usually prone to atavistic toff-grovelling, absolutely adored him: when Alcibiades finally returned to Athens in 407 BC after eight years of exile, sailing coolly into Piraeus on a ship with purple sails, they welcomed him back with paroxysms of joy.
