The Bentivogli sent it to the Duke Alfonso d'Este of Ferrara, who was a famous engineer and gunsmith.

He kept the head intact, but cast a huge cannon out of part of the material, which took the name of La Giulia.

What became of the head is unknown.

It is said to have weighed 600 pounds.
So perished another of Michelangelo's masterpieces; and all we know for certain about the statue is that Julius was seated, in full pontificals, with the triple tiara on his head, raising the right hand to bless, and holding the keys of S.Peter in the left.
Michelangelo reached Florence early in March.

On the 18th of that month he began again to occupy his house at Borgo Pinti, taking it this time on hire from the Operai del Duomo.
