Antonio Pollaiuolo painted three small pictures of Heracles for Lorenzo il Magnifico, each about 17cm high. One of them seems to be lost, the other two are in the Uffizi. Vasari writes:
The first of these, which is slaying Antaeus, is a very beautiful figure, in which the strength of Hercules as he crushes the other is seen most vividly, for the muscles and nerves of that figure are all strained in the struggle to destroy Antaeus. The head of Hercules shows the gnashing of the teeth so well in harmony with the other parts, that even the toes of his feet are raised in the effort. Nor did he take less pains with Antaeus, who, crushed in the arms of Hercules, is seen sinking and losing all his strength, and giving up his breath through his open mouth.
Antaeus was the son of Poseidon and Gaia, invincible as long as his feet touched the ground. Heracles, on discovering his secret, lifted him up and crushed him in his arms.
