The first version is also known as Murtula, by the name of the poet who wrote about it, Gaspare Murtola (d. 1624): "Flee, for if your eyes are petrified in amazement, she will turn you to stone." It measures 48 by 55 cm and is signed Michel A F (Latin: Michel Angelo Fecit), "Michel Angelo made [this]", Michelangelo being Caravaggio's first name. This work is privately owned.
