A robot that is one of da Vinci's lost inventions. The Italian government asked da Vinci, near the end of his life, to build them a device that could protect the treasures of the Milan cathedral so he built them a guardian that'd attack thieves and treasure hunters. It worked too well, however, and attacked anyone that came near the cathedral.
Records from Warehouse 8 indicated that it was only recovered after a lucky bolt of lightning struck it, deactivating it long enough for it to be snagged and bagged.
It was accidently activated when the Norge Porthole was improperly placed in its' aisle. A Tesla blast wouldn't be strong enough to deactivate it so instead Artie ran an electric current from the Tesla Targetting Coil through Hans von Bulow's Piano Wire and then wrapped the wire around an arrow. Steve acted as the bait to lure the Gargoyle in close enough for Myka to shoot the arrow into it. Artie then ran the electricity into the Wire which deactivated the Gargoyle and caused it to crash down into the Warehouse floor.
Leonardo da Vinci was an Italian painter, draftsman, sculptor, architect, and engineer who has often been described as the ideal Renaissance man, someone who has an "unquenchable curiosity" and who is "feverishly inventive imagination". His Last Supper and Mona Lisa are among the most widely popular and influential paintings of the Renaissance. His notebooks reveal a spirit of scientific inquiry and a mechanical inventiveness that were centuries ahead of their time. Da Vinci's studies in science and engineering are as impressive and innovative as his artistic work. Da Vanci filled hundreds of notebooks with sketches and blueprints for inventions. During his lifetime Leonardo was valued as an engineer. In a letter to Ludovic il Moro he claimed to be able to create all sorts of machines both for the protection of a city and for siege. When he fled to Venice in 1499 he found employment as an engineer and devised a system of moveable barricades to protect the city from attack. He also had a scheme for diverting the flow of the Arno River. Da Vinci was also interested in the phenomenon of flight; he produced many studies of the flight of birds and plans for several flying machines including a hang glider and a helicopter.
