1499

Quotations and notes on books and authors.

Theophrastus on the ebb and flow of the tide, and of eddies, and on water. [Footnote: The Greek philosophers had no opportunity to study the phenomenon of the ebb and flow of the tide and none of them wrote about it. The movement of the waters in the Euripus however was to a few of them a puzzling problem.]

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