Hand from a statue on a head of a lion

A bigger than lifesize left hand from possibly a god or mythological statue of Hercules. The hand is resting on the top of a lion's head, clasping it from its thick mane. The lion has big and wide eyes and its mouth is open, the big tongue can be discerned. A round feature, described in the old inventory as a claw can also be seen on the left side of the wrist. The left side of the fragment is also very flat and round and suggests that that this was a big free standing statue.
