The cast reproduces a larger than natural statue, depicting the god Poseidon, standing, with the weight unloaded on the right leg and the right leg at rest, discarded laterally and set back. The god's head is turned to the left and looks at a distant point. The musculature is strongly modeled; dressed only in the himation which, resting on the left shoulder, covers the lower part of the body. The god holds a flap of the cloak with his left hand, while with his right he had to hold a high trident. Without the nose and part of the beard and hair. Near the right leg there is a dolphin used as a support. The original work, from which the cast derives, is dated to the last quarter of the 2nd century BC, today preserved in the National Museum of Athens, it was found in Melos in 1877, reassembled and restored.
