Thangka (also spelled thanka, tangka, or tanka) comes from Tibetan thang-ka, a compound of thang (flat, a plain, a surface) and ka (white, bright, clear). The word thus means something like 'recording on a flat surface' or 'thing painted on a flat ground' — a practical description that emphasizes the support rather than the subject. The Tibetan tradition distinguishes several types of scroll paintings by material and technique: thangkas painted on cloth or silk with mineral pigments and gold are the most common; appliqué thangkas (gos-thang) assembled from cut silk and brocade rather than painted are used for large ceremonial display; embroidered thangkas are produced in monasteries with significant weaving traditions. The English word thangka entered scholarly use in the late nineteenth and early twentieth centuries through Tibetological literature — Csoma de Körös's early studies, the work of Sarat Chandra Das, and the foundational art-historical research of Giuseppe Tucci, whose Tibetan Painted Scrolls (1949) remains the foundational scholarly treatment.

The thangka tradition traces its origins to the emergence of Vajrayana Buddhism in Tibet from the seventh century onward. As Tibetan monks and translators brought Tantric teachings from India and Nepal, they brought with them the iconographic tradition of depicting deities in carefully codified forms: each deity of the Vajrayana pantheon has a precise set of attributes — a specific number of arms, specific objects held in specific hands, a specific color, a specific seat, a specific aureole — and depicting these attributes correctly was not merely a matter of artistic convention but of doctrinal accuracy. An incorrectly depicted deity could not serve as a support for visualization practice; the painting had to match the mental image described in the sadhana (liturgical text) because meditators would use the thangka as an external support for the internal construction of the deity's form in meditation.

The making of a thangka was itself a sacred activity governed by precise rules. The cloth support was first prepared with a ground of chalk or gesso (tsä), then polished smooth. The composition was laid out using a geometric grid system derived from canonical iconometric texts (thig-rtsa) that specified exact proportions for every element of a deity's body. Mineral pigments — lapis lazuli for blue, malachite for green, cinnabar for red, gold for the aureole and ornaments — were applied in thin, precise layers, each color following a set sequence. The outline was drawn in black ink. Gold was burnished after application to create its characteristic glow. The most critical moment was the 'opening of the eyes' (mig-dbab) — the final ritual act in which the officiant, in a state of meditative concentration, painted the pupils of the deity's eyes, completing the transformation of the painting from a colored cloth into a living presence.

Thangkas entered Western art markets in significant quantities from the late nineteenth century onward, first as curiosities collected by colonial-era travelers in Darjeeling and Lhasa, then as recognized art objects in their own right. Heinrich Harrer, who spent seven years in Tibet before the 1950 Chinese occupation, described thangkas hanging in every household as naturally as Western families hung paintings. After the Tibetan diaspora following 1959, the thangka tradition was preserved and transformed in exile communities in Dharamsala, Kathmandu, and Bhutan. Contemporary thangka painters trained in the traditional iconometric canons now work for international collectors as well as religious institutions, and the question of whether a thangka made for commercial sale rather than devotional use retains its sacred character has become one of the more interesting problems in the ethics of sacred art.
