stuck after finding Agrippa

[kastanok]

I got stuck here too.

HINT

Spoiler below!

If you stand near Agrippa, you can hear a machine working nearby. Maybe you can fix it?

SOLUTION

Spoiler below!

Move a couple of boxes from under the stairs onto the operating table to the left. Stand on the boxes and look up. Open the trap door in the ceiling. You will see some cogs. Slide the third cog from the left upwards. Now the two levers in the room at the top of the stairs will open the two big doors you need to get through.
