An Odalisque (Turkish: Odalık) was a female slave in an Ottoman seraglio. She was an assistant or apprentice to the concubines and wives, and she might rise in status to become one of them. Most odalisque were part of the Imperial Harem, that is, the household, of the sultan.
Many artists, especially classical artist such as Jean August Dominique Ingres, who in 1814 painted the Grand Odalisque, often portrayed female nudes in this style. Hence the original use of the word as a noun has morphed within the field of paintings into an adjective which used to describe a particular style of portraying a female nude.
Two of into my favorite artists, Amedeo Clemente Modigliani (July 12, 1884 – January 24, 1920 and Fernando Botero Angulo (born April 19,1932 - present), depict stylized Odalisque at opposite ends of the spectrum. Both artists portray women in exaggerated proportions, Modigliani chose to elongate his figures, while Botero chose to accentuate corpulence. I find in each a more natural, albeit caricature, portrayal of women because these artists do not seek perfection through idealization.
Whereas the nudes of the great artists like Michaelangelo strive to not only portray physical perfection of the body types of their age, it seemed as if the artists sought to imbue the canvas with the very essence of the model's soul. By contrast, Modigliani and Botero seek to explore other aspects of painting and the female nude.
Modigliani was born into an Italian-Jewish family from Livorno, Italy. He moved to Paris in 1906 where he met a female poet, Anna Akhmatov who became the inspiration for many of his paintings."
"One of the key-elements of Modigliani's portraitism were the slated heads, derived from Byzantine cariatides because of the horizontal placement of the eyes and mouth coupled with the curvature of the nose. The portraits subtlety is due to Modigliani's unique talent, but its essence, the facial constructions one of the most important artistic inventions of modern art." Source: Paintings.Name
