What is the name of the statue in Florence?

The statues in the Piazza Vecchio, by the entrance, are a replica of Michelangelo's David on the left, and the statue on the right is Hercules and Cacus, by Bandinelli. To the right in the Loggio dei Lanzi in the Piazza DELLa Signoria there are other statues - Perseus holding Medusa's head, and the Rape of the Sabine Women. Hope this helps!
