Modigliani - La belle romaine Nude sitting on a Divan
This series of nudes was commissioned by Modigliani's dealer and
friend Leopold Zborowski, who lent the artist use of his apartment,
supplied models and painting materials, and paid him between fifteen
and twenty francs each day for his work. The paintings from this
arrangement were thus different from his previous depictions of friends
and lovers in that they were funded by Zborowski either for his own
collection, as a favor to his friend, or with an eye to their "commercial
potential", rather than originating from the artist's personal circle of
acquaintances.
