King Louis' XIV desk
So that the king did not have to put away whatever he happened to be working on whenever he stepped away, this desk had a couple of special features built into it. It had a clever (new at the time) cover that rolled down to secure everything on his desk. This was either the first rolltop desk or one of the first ones ever made. And because of this, the ink wells were in a special removeable compartment that was accessed through a hidden door on the side of the desk that open at the push of a button.
