Bronze Centaur Statue

Bronze statue of a Centaur. Half man half horse fighting a large serpent with a spear. On the back left corner engraved in the bronze is D Grillo 85. The measurements and 13.5 inches tall 12.5 inches long and 6.25 inches wide. It’s mounted to a marble base. Very fine detail in the hands, face feet and serpent. I’ve googled numerous times for hours and can’t find any information except an artist named Grillo participated in an art show in Africa and the theme was “Gods”. Idk if this is the statue used of that or which artist Grillo it was. Any information would be greatly appreciated and I do thank you.
