1478-1518, Notebook of Leonardo da Vinci (''The Codex Arundel''). A collection of papers written in Italian by Leonardo da Vinci (b. 1452, d. 1519), in his characteristic left-handed mirror-writing (reading from right to left), including diagrams, drawings and brief texts, covering a broad range of topics in science and art, as well as personal notes. The core of the notebook is a collection of materials that Leonardo describes as ''a collection without order, drawn from many papers, which I have copied here, hoping to arrange them later each in its place according to the subjects of which they treat'' (f. 1r), a collection he began in the house of Piero di Braccio Martelli in Florence, in 1508. To this notebook has subsequently been added a number of other loose papers containing writing and diagrams produced by Leonardo throughout his career. Decoration: Numerous diagrams.

Nearly a hundred years before Galileo and two hundred years before Newton, in a series of diagrams and notes in the Codex Arundel, Da Viinci was able to calculate the gravitational constant to an accuracy within 10 percent of the accepted value.

Da Vinci composed a collection of hundreds of papers from 1478 and 1518 which are now bound in the Codex Arundel, named for the Earl of Arundel who acquired it in the 17th century.

While Americans and Germans call Leonardo da Vinci's painting the Mona Lisa, the French refer to it as La Joconde.

What do the French call the Mona Lisa? :: La Joconde

Lorenzo Nigro indicates that the "kothon" of Motya in southern Sicily was a pool of Baal whose surface may have been used to observe and map the stars. He also indicates that the Phoenicians adored the stars potentially as gods or deceased ancestors. This is an example of a potentially false assumption often seen in archaeology of Western practitioners misconstruing Indigenous practices based on modern ideas of religion and culture.

I might posit that this sort of practice is more akin to that of the science of Indigenous peoples who used oral and mnemonic methods in combination with remembering their histories and ancestors.

Cross reference this with coming reading in The First Astronomers (to come) which may treat this in more depth.

Leonardo da Vinci documented the attributes of standing water for studying the night sky.

Where was this and what did it actually entail?
