Raffaello Sanzio | Drawings

Over forty sketches survive for the Disputa in the Stanze, and there may well have been many more originally; over four hundred sheets survive altogether.

He used different drawings to refine his poses and compositions, apparently to a greater extent than most other painters, to judge by the number of variants that survive: "...This is how Raphael himself, who was so rich in inventiveness, used to work, always coming up with four or six ways to show a narrative, each one different from the rest, and all of them full of grace and well done" wrote another writer after his death.

For John Shearman, Raphael's art marks "a shift of resources away from production to research and development". When a final composition was achieved, scaled-up full-size cartoons were often made, which were then pricked with a pin and "pounced" with a bag of soot to leave dotted lines on the surface as a guide.

He also made unusually extensive use, on both paper and plaster, of a "blind stylus", scratching lines which leave only an indentation, but no mark.

These can be seen on the wall in The School of Athens, and in the originals of many drawings. The "Raphael Cartoons", as tapestry designs, were fully coloured in a glue distemper medium, as they were sent to Brussels to be followed by the weavers.

In later works painted by the workshop, the drawings are often painfully more attractive than the paintings. Most Raphael drawings are rather precise-even initial sketches with naked outline figures are carefully drawn, and later working drawings often have a high degree of finish, with shading and sometimes highlights in white.

They lack the freedom and energy of some of Leonardo's and Michelangelo's sketches, but are nearly always aesthetically very satisfying.

He was one of the last artists to use metalpoint (literally a sharp pointed piece of sliver or another metal) extensively, although he also made superb use of the freer medium of red or black chalk. In his final years he was one of the first artists to use female models for preparatory drawings-male pupils ("garzoni") were normally used for studies of both sexes.
