The Thangka Painting and Its History in Bihar

Ranjan Itik Kamal

Thangka painting represents a sophisticated paradigm of Himalayan Buddhist iconography, originating in Tibet and proliferating through Bhutan, Nepal, and northern India. These scroll paintings, executed on textile substrates, function as indispensable liturgical instruments for meditative praxis and didactic instruction. This study examines the evolutionary trajectory of Thangka art as a reflection of the multifaceted cultural and religious exchanges facilitated by trans-Himalayan trade and pilgrimage networks. Thangka paintings, as they travelled across different regions, often adapted and blended with local artistic styles and cultural aesthetics. The production of Thangka is a highly disciplined process governed by orthodox iconometric treatises. This technical methodology involves the preparation of a lime-primed cotton canvas, followed by the application of a precise geometric grid to ensure the proportional integrity of divine figures. The utilization of noble materials, including lapis lazuli, cinnabar, and gold, underscores the symbolic and metaphysical depth of the medium. Furthermore, the practice of mounting these works on silk brocade facilitates their portability, reinforcing their status as "mobile sanctums" within nomadic and monastic contexts. Finally, this paper evaluates the pivotal role of the scholar Rahul Sankrityayan in the twentieth-century repatriation of this heritage to Bihar. By recovering an extensive corpus of manuscripts and Thangkas during his Tibetan expeditions, Sankrityayan sought to bridge the historical lacuna left by the decline of Buddhism in India’s medieval heartland. His efforts – culminating in the significant collections housed within the Patna Museum – not only preserved critical artifacts of Buddhism but also re-established Bihar’s ancestral connection to the broader Buddhist world, fostering a contemporary revival of scholarly and cultural interest in the region’s Himalayan ties.
