Drafts for paintings realized by Michelangelo's friends

Sebastiano del Piombo came to Rome in 1511 and soon became friends with Michelangelo, who took him under his wing. Sebastiano worked with Michelangelo, from whom he took his use of drawing as the basis of his compositional structure, as well as the monumental conception of his figures. Michelangelo admired Sebastiano's coloration and made drafts for the paintings of his friend, who could not compete with the master with regard to compositional and heroic figural concepts.

Michelangelo also provided preparatory drawings to his friend, Daniele da Volterra, who elaborated the details or developed them further independently.
