|A page from one of DaVinci's journals|
On this day in 1980, American oil tycoon Armand Hammer pays $5,126,000 at auction for a notebook containing writings by the legendary artist Leonardo da Vinci.
The manuscript, written around 1508, was one of some 30 similar books da Vinci produced during his lifetime on a variety of subjects. It contained 72 loose pages featuring some 300 notes and detailed drawings, all relating to the common theme of water and how it moved. Experts have said that da Vinci drew on it to paint the background of his masterwork, the Mona Lisa. The text, written in brown ink and chalk, read from right to left, an example of da Vinci’s favored mirror-writing technique.Journal writing is way older than da Vinci but he is almost the Great-Grandad of journaling. They are absolutely wonderful to leaf through and a lot of them are on the web and you can get an ebook version for free on Amazon
