'The Virgin in Prayer' by Sassoferato. It took me long time to choose a subject to draw despite having choice from a limited number of rooms so I only had an hour. But I'm learning to look beyond the subject matter which doesn't necessarily appeal to the underlying structure. The more I drew , the more excited I got, finding repetitive shapes (especially triangles) and connections and I realised that it reminded me a lot of the neoclassical period of Picasso.
Leonardo Da Vincis' Burlington House Cartoon . It's modelled with relatively few tones - the same tone can look different optically according to what it's' next to so it's critical to keep making comparisons. This was what we were to look for and bring out in our sketches - so no pressure then!
'Virgin of the Rocks' to see how that had been carried through into paint, we spent some time debating whether the background blue of Bellinis's 'The Doge, Leonardo Loredan'was the same throughout (it is) as it looks lighter against the RH side in shadow . The complimentary orange of his cap adds to this.
Chiaroscuro of ' St Francis in Meditation' by Zurbaran
Seurat's 'Bathers at Asinieres' ( and the oil sketches alongside). While we waiting for a slot among all the tour groups, we were shown some of the sketches in an exhibition catalogue where he'd started with details such as folds in the shirt fabric but then had simplified. I'd forgotten how much I liked his drawings, so was pleased when I got home to track down a book I bought over 30 years ago.
