Leonardo da Vinci’s Notebooks
This is a drawing from one of Leonardo da Vinci’s notebooks. Even though he lived in the late 1400s, we still know a lot about this amazing artist and engineer. He was curious about everything. Somethings he studied, like anatomy, were related to his painting, so he his drawings of hands are so life-like. But he also drew flying machines, like this, long before there were the earliest working helicopters in the early 1900s.
