(b. 1452, Vinci, d. 1519, Cloux, near Amboise)

Male head in profile with proportions

c. 1490
Pen and ink on paper, 280 x 222 mm
Gallerie dell'Accademia, Venice

The profile head contains notes on proportion such as "the size of the figure is eight heads." Above the notes on the left is a circle with a line through it, meaning that the text was included by Melzi in the treatise on painting. Leonardo not only produced studies of the proportions of the human head, but also a table in which he recorded all possible types of noses. In addition, he combined various forms of foreheads and chins as well as different types of noses and mouths.
