Da Vinci's Study

Before breaking for lunch, museum guards at Leonardo Da Vinci's historic home absentmindedly left the door open to the genius' private study. You can't help but seize the opportunity to sneak in for peak when a gentle breeze blows the door shut. And locked! You only have one hour before the guards return. Figure out a way to escape or the unsympathetic Italian courts will lock you up for a lot longer. Buona fortuna! (Good luck!)
