Now that yo have the invitation, head to the Castello. On the bridge, talk with the courtisans to initiate the memory.
Once in the Castello, you have to locate Leonardo's painting and mark them. There are two of them in the exhibition. You have to stay undetected.
When you are in control of Ezio, take the left or right path and head for the back of the castle. The exhibition is there.
The paintings are heavily guarded. The first painting can be located using the eagle vision. It is on the right side of the backyard. If you take the right path, you can hire courtisans that will distract the guards and allow you to mark the painting.
Once the first painting is marked, another part of the exhibition will be opened.
You can not enter because it is restricted. You wll have to climb all the way up. To access the top of the Castello, climb the builiding near the left part of the outisde exhibition. Kill the guard on the roof and cross to gain access to the wall. Climb, go left, up and right and jump on the beams. At some point, you won't be able to jump on the small roof attached to the wall. Fall down and grab the wall on the way down. Continue left and climb up to be on the upper part of the fortress. You now can get in the courtyard.
Go to the checkpoint. Get down the stairs and take the first door on your right. Go up the stairs. In the next room is the second Leonardo's painting. A guard is patroling. Wait for him to stop in front of the closest painting and kill him.
Leonardo's painting is on the north wall. Find it with the eagle vision and mark it.
You now have to escape the room. Two guards will arrive. Hide behind the big painting and wait for them to come near you and kill them. Leave from where you arrived and get in the courtyard. Climb to the top and use a parachute to leave the Castello.
The two paintings you marked will then be missing.
