"Empress Wu and Tang Buddhist Art" by Roderick Whitfield, Percival David Professor of Chinese and East Asian Art, School of Oriental and African Studies, University of London.
Wu Zhao, or Wu Zetian, is notorious as a ruthless woman who eliminated all who might stand in her way, becoming China's only female Emperor, changing the dynastic title from Tang to Zhou in 690 and dominating the Chinese court from the 650's until her death in 705. Relying on Buddhism to support her claim to the throne, she sponsored important translations of the sutras and fostered Buddhist art both in the capital and in faraway Dunhuang, the scene of several portents held to be auspicious for her rule. Her influence can be seen in the creation of a colossal image of Maitreya at the Mogao caves, as well as in mural paintings and the cult of Buddhist relics. information is provided, please address any queries as
