Believed to be the head of an Ooni, a ruler from the West African kingdom of Ife Circa AD 1000 to 1500. I think the Ife sculptors were some of the greatest portraitists that have ever lived. Collection of the British Museum.
Amedeo Modigliani - Tête, 1911-1912. Tête is one of 27 known sculptures by Modigliani and was made between 1910 and 1912. The limestone head stands over 2 feet tall and depicts the head of a woman wearing a tribal mask with her hair swept back. Modigliani was clearly inspired by the geometric designs of African sculpture and the simplification of form evident in the work of his mentor Constantin Brâncuși. It is among the most expensive works of art ever sold.
