Lucian Symposium 14

But even while he was eating he was not idle, for he talked of virtue and vice all the time, and scoffed at the gold and silver plate; for example, he asked Aristaenetus what was the use of all those great goblets when earthenware would do just as well. But he had begun to be a bore by this time, so Aristaenetus put a quietus on him for the moment by directing the waiter to give him a big bowl and pour him out a stiffer drink. He thought that he had had a good idea, little realising what woes that bowl was destined to give rise to. On taking it, Alcidamas kept quiet for a little while, throwing himself on the floor and lying there halfnaked as he had threatened, with his elbow squared under him and the bowl in his right hand, just as Heracles in the cave of Pholus is represented by the painters.

However, he did not let feeding interrupt his energetic expositions of virtue and vice, and his scoffs at gold and silver. What was the good of this multitude of wonderful cups, he wanted to know, when earthenware would serve the purpose? Aristaenetus got rid of his obtrusiveness for the moment by signing to his servant to hand the cynic a huge goblet of potent liquor. It seemed a happy thought; but he little knew the woes that were to flow from that goblet. When Alcidamas got it, he was quiet for a while, throwing himself on the ground in dishabille as he had threatened, with his elbow planted vertically, just in the attitude of the painters’ Heracles with Pholus.
