The illustrated thesaurus presented was developed in the frame of the project Himalayan Rock Art Database (HiRADa). It draws upon previous efforts of standardization in the field of rock art studies in general and Himalayan rock art in particular. The thesaurus is a resource for the standard description of Himalayan Rock Art: it consists in 358 hierarchized terms most of them with precise definitions and 223 illustrations (for a total of 557 drawings). Content The three main concepts of the thesaurus reflect a multi-scalar approach to rock art which consists in recording its location (site and zone), its support (rock and surface) and its art (motif and scene). -Location: the concept designates a rock art site that may have one or more zones (one zone minimum): 90 concepts. -Support: the concept designates a rock bearing motif(s), either engraved (petroglyph) or painted (pictograph) that may have one or more surfaces (one surface minimum): 38 concepts. -Art: the concept designates a motif which is a man-made (anthropic) trace engraved (petroglyph) or painted (pictograph) onto a natural surface of rock. The motifs may form a scene(s) by their interaction or association: 230 concepts. Illustrations are available online in a specific image collection on Nakala (223 images): https://nakala.fr/collection/10.34847/nkl.23f1xxk4
