Leonardo's Inventions

Leonardo da Vinci described and sketched ideas for many inventions that were hundreds of years ahead of their time, but very few were ever built or tested during his lifetime. Though his notes suggest that he wished to organize and publish his ideas, he died before he could accomplish this important goal.

After his death, his notebooks were hidden away, scattered, or lost, and his wonderful ideas were forgotten. Centuries passed before other inventors formed similar ideas and brought them to practical use.

Browse Leonardo's machinery sketches and test your knowledge of which invention they eventually became.

"Machine Gun" is correct — great job! This machine consisted of three sets of guns, set on a rotating triangular drum. A row of guns was placed on each side of the drum; when the first set of guns fired, the force of the explosion would propel those guns back, bringing the next set of guns to the top, ready to be fired.

  • Assembler
  • Stretcher
  • Thread Cutter
  • Radio

"Thread Cutter" is correct — great job! This machine creates screws. It cuts a thread, or groove, around a central core to form the helix shape of a screw. A cutting blade is attached to two long guide screws on the bed of the table. As the cranks on the end of the table were turned, a cutting blade would run down the two guide screws, cutting a third bar placed between the two into an identical third screw.

A stone would be laid on the top of the arched wooden beam and the release mechanism would be tightened with the gear. When the beam was released, the force of the release would catapult the stone into the air.
