Important wooden crowned buddha, Myanmar / Burma, 12th to 13th century The figure stands in samabhanga, with his right hand in varadamudra and the left holding a section of his garment. He wears a sanghati and an elaborate necklace. His face displays a serene expression with downcast eyes below arched eyebrows, faint smiling lips and elongated earlobes. His hair is combed in a chignon topped with a finial and secured with a tiara.
This fine crowned Buddha figure from the Bagan empire period (ca. 1050 – 1287), named after its capital, stands at almost life size. It was likely once placed in its own shrine, originally gilded and painted. The most distinctive iconographic feature is his elaborate crown. Crowned and bejewelled Buddhas became popular in northeastern India during the Pala period under the increasing influence of Vajrayana Buddhism. It symbolized the spiritual sovereignty of the Buddha. Its concept spread specially to neighbouring Bagan as Pala art can be seen as the model of Bagan art and further over the mainland of Southeast Asia to the Khmer empire around the same time.
