Leonardo da Vinci (Vinci 1452-Amboise 1519)
Cloud formations c.1517-18
RCIN 912391
A study of cloud effects: three layers of strata nebulae and a cumulus. Below is what may be a dark cumulus, or the top of mountain peaks. There is a note on clouds along the centre at the top. The sheet is very much rubbed. It may well have been joined to another originally.
