Codex Leicester (also briefly known as Codex
Codex Hammer) is a collection of famous scientific writings by Leonardo da Vinci. The Codex
Codex is named after Thomas Coke, later created Earl of Leicester, who purchased it in 1719. Of Leonardo's 30 scientific journals, the Codex may be the most famous of all. The manuscript currently holds the record for the second highest sale price of any book, as it was sold to Bill Gates
Bill Gates at Christie's
Christie's auction house on 11 November 1994 in New York for US$30,802,500 (equivalent to $50,858,000 in 2017). The Codex
Codex provides an insight into the inquiring mind of the definitive Renaissance
Renaissance artist, scientist and thinker as well as an exceptional illustration of the link between art and science and the creativity of the scientific process. Overview The manuscript does not take the form of a single linear script, but is rather a mixture of Leonardo's observations and theories on astronomy; the properties of water, rocks, and fossils; air, and celestial light. The topics addressed include:
an explanation of why fossils can be found on mountains. Hundreds of
years before plate tectonics became accepted scientific theory,
Leonardo believed that mountains had previously formed sea beds, which
were gradually lifted until they formed mountains.
the movement of water. This is the main topic of the Leicester Codex.
Among other things, Leonardo wrote about the flow of water in rivers,
and how it is affected by different obstacles put in its way. From his
observations he made recommendations about bridge construction and
the luminosity of the moon. Leonardo speculated that the moon's
surface is covered by water, which reflects light from the sun. In
this model, waves on the water's surface cause the light to be
reflected in many directions, explaining why the moon is not as bright
as the sun. Leonardo explained that the pale glow on the dark portion
of the crescent moon is caused by sunlight reflected from the Earth.
Thus, he described the phenomenon of planetshine one hundred years
before the German astronomer
