This marble is a Grand Tour piece "after the antique" and depicts Bacchus with his arm around the shoulder of Ariadne as he draws her cloak about her. His other hand is inside the cloak in the act of pulling it across himself, as if for protection or to isolate them from the rest of the world.
Bacchus has just discovered Ariadne on the island of Naxos, where she was dumped by Theseus. He immediately falls in love with her, and this is the moment when they first realise their feelings.
It is Cararra marble and was made in Italy in the first half of the nineteenth century.
