Hot-headed Rocco is keen to raise an army against Milan though De Medici dislikes the idea as it could expose him as the murderer. He persuades Leonardo to build a super-weapon,modelled on the hard shell of a tortoise,which will resist bullets and cannonballs. An early trial accidentally blows up a statue of the duke but Rocco is impressed by Leonardo's second attempt and De Medici plans to use it in his attempt on Rocco's life. Angelica realises that she is drawn to Macchiavelli and tells Lorenzo that she wants to call the wedding off but his father insists it go ahead.
