The starting-place is in the shape of the prow of a ship, and its prow is turned towards the course.

The man appointed to start the racing sets in motion the mechanism in the altar, and then the eagle has been made to jump upwards, so as to become visible to the spectators, while the dolphin falls to the ground.
