Mercury and the Tradesmen
When Jupiter was creating man, he told Mercury to make an
infusion of lies, and to add a little of it to the other
ingredients which went to the making of the Tradesmen. Mercury did
so, and introduced an equal amount into each in turn — the
tallow-chandler, and the greengrocer, and the haberdasher, and all,
till he came to the horse-dealer, who was last on the list, when,
finding that he had a quantity of the infusion still left, he put
it all into him. This is why all Tradesmen lie more or less, but
they none of them lie like a horse-dealer.
