Learn moreOn Sleep is a work of the Greek philosopher and scientist Aristotle, included in the collection Parva Naturalia.
The Parva Naturalia (a conventional Latin title first used by Giles of Rome: "short treatises on nature") are a collection of seven works by Aristotle, which discuss natural phenomena involving the body and the soul. They form parts of Aristotle's biology.
Aristotle (384–322 BC) was a Greek philosopher and polymath during the Classical period in Ancient Greece. His writings cover many subjects – including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theater, music, rhetoric, linguistics, politics and government – and constitute the first comprehensive system of Western philosophy.
