The Tibetan Buddhist Canon Kangxi Kangyur, completed in 1669, features 756 painted miniatures on its inner protective cover planks. These elaborated images seem to be the earliest set of Buddhist miniature paintings on a grand scale found so far. In this thesis, the author investigated the causes that may contribute to making the Kangxi Kangyur. Judging from the format and topics of Buddhist iconographies, the Kangxi Kangyur might be a significant referent source for later works of Buddhist paintings as well as statues in the Ching imperial court. Since most Tibetan Buddhist iconographies are made according to Buddhist sadhana texts, the author tried to find the correlations between the 756 painted miniatures by comparing two crucial sadhana collections: the yi dam rgya mtsho'i sgrub thabs rin chen 'byung gnas and rgyud sde kun btus. The preliminary result is the ten possible combinations of mandala deities and the corrections of Tibetan and Chinese names of the Twelve Yakṣa Generals images on the inner cover planks of the Kangxi Kangyur.
