Tsongkapa & the Eighty-four Mahasiddhas
As a sub-theme of the Five Forms of Tsongkapa, the mahasiddha form is sometimes depicted as the central figure of a composition surrounded by smaller figures of the Eighty-four Mahasiddhas. So far six paintings have been identified with four of them included on the HAR website.
Two of the HAR images belong to sets likely likely including depictions of the other forms of Tsongkapa: HAR #65347, 77237. Three of the remaining paintings appear to have all been created based on a single model. Two of these are HAR #74042 and 90748. All of the individual compositions and sets of paintings identified thus far depict the Eighty-four Mahasiddhas according to the Vajrasana System.
