Page "Raphael" Paragraph 43
Vasari says that Raphael eventually had a workshop of fifty pupils and assistants, many of whom later became significant artists in their own right.
This was arguably the largest workshop team assembled under any single old master painter, and much higher than the norm.
They included established masters from other parts of Italy, probably working with their own teams as sub-contractors, as well as pupils and journeymen.
We have very little evidence of the internal working arrangements of the workshop, apart from the works of art themselves, often very difficult to assign to a particular hand.
