The great Puruṣottama-Jagannātha temple of Purī stands on the shore of the Bay of Bengal in the Indian state of Oḍiśhā. Built in the 12th century AD by Anantavarman Coḍagaṅga Deva (1077-1147AD) of the Eastern Gaṅga dynasty, it represents a typical Oḍiśhān temple at its best. This is the largest and tallest surviving temple of Oḍiśhā. In evolution of the Oḍiśhān temple style, this temple is a near duplicate of the Liṅgarāja temple of Bhubaneswar and provided the model for the subsequent Sun temple at Koṇārk, where the Oḍiśhān style of temple architecture attained its finality and fulfilment. The present monograph is a comprehensive scientific treatise critically examining and evaluating the Puruṣottama-Jagannātha temple of Purī in all aspects such as its history, architecture, sculpture, icono-graphy, rituals, festivals, organisation of services, conservation measures, etc. It tries to depict, in all details, the art and architecture of the temple in a broader Indian framework, as well as in the context of regional developments. An unbiased interpretation of the original sources like the inscriptions, Purānas and other literary works, the Mādalāpāñji (the chronicle of Puruṣottama-Jagannātha temple), etc. have been strictly adhered to in order to trace the origin, antiquity, history, rituals, festivals etc. of the temple. The monograph supplemented by 15 nos. of appendices, 50 nos. of figures and 22 nos. of plates will remain a standard work of reference and prove a veritable mine of information for scholars and general public interested in the Indian art and culture in general and that of Puruṣottama-Jagannātha temple in particular.
