Last update: 11 May 2016
Eavesdrop on the conversation between master and servant to find out that Leonardo has hidden Archimedes' scroll very well and information about the hiding place is stored in some kind of cylinder in his workshop. So you have to find it.
Look at the interesting construction on the wall at background. It looks like a scales but it is too dark to see it.
Go to the table with empty amphora. On the plate to the left you'll find some kind of device, looking like lighter. Take it.
Notice that there is an oil lamp with concave mirror mounted on the strange vehicle next to the wall with the scales. Light it with the lighter. It turns out that this is a prototype of the headlamp, which can lighten the wall.
Since the left part of the scales is still in darkness, examine the right one - it is blocked. Although there is nothing loaded on it, it is lowered and you can't move it up. Nina will notice a small hole in it.
Now take some kind of the wooden jack, standing next to the wall on the right.
Use the jack on the vehicle to raise it up and light up the wall. Now you can see the left arm of the scales. Nina will notice there the cylinder she's looking for. Not you only have to get it.
To do this, take the chisel hanging on the wall to the left.
Use it on the right arm of the scales to unlock the mechanism.
Once the left arm lowers, take the cylinder from the box on the arm.
