And to represent the storm accurately you must first show the clouds scattered and torn, and flying with the wind, accompanied by clouds of sand blown up from the sea shore, and boughs and leaves swept along by the strength and fury of the blast and scattered with other light objects through the air. […] Let the sea be rough and tempestuous and full of foam whirled among the lofty waves, while the wind flings the lighter spray through the stormy air, till it resembles a dense and swathing mist.
- Leonardo da Vinci, The Notebooks of Leonardo Da Vinci, trans. Jean Paul Richter, vol. I, 1888, § 606, “How to Represent a Tempest.”
