Focus on Odalisque with Raised Arms and explain the Matisse's sources.
This painting is in dialogue with the tradition of the reclining female nude. The history of the depicting the nude female figure is far too vast to contrast Odalisque with Raised Arms with every painting of a nude woman. It is notable that modern painting was especially interested in straying from convention, and teachings from academic art. This slight rebellion can be seen in the manner in which Matisse paints his subject. She is only semi-reclined, her eyes are open, and though she is not engaging with the viewer by eye contact she seems to exude a level of awareness. Her attitude is reminiscent of Édouard Manet's Olympia. 
The gaze of the prostitute in the painting prevents easy contemplation of her body, she is guarded, she is challenging you, and she is dominating the relationship between the viewer and herself, with her as the object being viewed.
