Nothing is certain until one possesses it. This old proverb is thought by many to come from the ancient Greek legend of Antaeus, helmsman of the ship Argo. A slave told him he would never live to taste the wine from his own vineyard. As some wine from his grapes was set before him, he sent for the slave to show him his mistake, but the slave allegedly said, “There’s many a slip ’twixt the cup and the lip.” Just then a messenger arrived, telling him the Calydonian boar was destroying his vineyard. Antaeus jumped up, set down his wine, and went out to kill the boar, but was himself killed by the ferocious animal. Another writer believes the phrase comes from Homer’s Odyssey, in which Odysseus aimed an arrow at Antinous as he was about to drink some wine. The arrow hit him in the throat, and the cup fell from his hands before he could drink.
