This entry from one of Leonardo da Vinci’s journals shows the exceptional plans that Leonardo da Vinci had for humans. The sketch also shows da Vinci’s understanding of how birds had the special ability to fly in the air. Unfortunately, this figure was not created; but we get our planes and our knowledge of ornithology from da Vinci’s fabulous ideas.
