Then we rushed upon him with a shout and seized him; on which he began at once with his old tricks, and changed himself first into a lion with a great mane; then all of a sudden he became a dragon, a leopard, a wild boar; the next moment he was running water, and then again directly he was a tree, but we stuck to him and never lost hold, till at last the cunning old creature became distressed, and said, Which of the gods was it, Son of Atreus, that hatched this plot with you for snaring me and seizing me against my will? What do you want?' "
