Leonardo da Vinci and the Voynich Manuscript

In the astronomical drawing of the Milky Way, the stars travel through the night sky in a clockwise direction. As the stars rise in the sky in the East and set in the West, traveling in a counter clockwise direction, this drawing is a mirror image of what actually takes place. Leonardo is famous for is his mirror image writing and drawing and is probably unique in the use of this idiosyncrasy.
