Helios, found at the Esquiline in Rome. The piece is made from Carrara marble and dating from the 4th century BC.
Helios, or Hyperionides/Hyperion (by his father), is showing up now and then, even thou I've found more depictions in mosaics than in sculpture. The god is easily recognized by his sun rays which spread out from the head and he can also be seen with a torch or globe.
Be cautious though, the rays might have been broken off and they were commonly made out of metal (i.e. Bronze) in which case you'll find a series of empty holes around the head.
