Of rainbows and rain.

When the air is condensed into rain it would produce a vacuum if the rest of the air did not prevent this by filling its place, as it does with a violent rush; and this is the wind which rises in the summer time, accompanied by heavy rain.

Taken from The Notebooks of Leonardo da Vinci edited by Jean Paul Richter, 1880.
