It was found in the Theatre of Dionysus in the Acropolis in the year 1862, and dubbed "Apollo Omphalos" because it was thought to have originally stood on an omphalos-shaped base.

[1] Apollo Omphalos is nude, standing firmly on his right leg while the left one is relaxed, slightly bent at knee-height; the pose's strong contrapposto causes the god's buttocks to move to the right.

[1] The statue is a second century AD Roman copy of an original Greek bronze one that was produced around 460-450 BC,[2] and attributed to either Kalamis or Onatas.

[1] Waldstein tried to argue that the original sculpture was produced by Pythagoras of Rhegium, but this has been rejected.

[2] The art movement it copies is the Archaic Greek art, which one can tell from Apollo's haircut, his stiff pose, the wide shoulders, the smaller head, and his face's rather vacant expression; nevertheless the body's composition shows the great knowledge and perception of nature of its artist.
