This archaeological and art-historical study is woven around rock art and ancient metallic articles attributed to Tibet. The silver bowls, gold finial, and copper alloy spouted jars and trapezoidal plaques featured are assigned to the Iron Age and Protohistoric period. These rare objects are adorned with zoomorphic subjects mimicking those found in rock art and embody an artistic zeitgeist widely diffused in Central Eurasia in Late Prehistory. Diverse sources of inspiration and technological capability are revealed in these objects and rock art, shedding light on their transcultural dimension. The archaeological and aesthetic materials in this work prefigure the Tibetan cosmopolitanism of early historic times promoted through the spread of Buddhist ideas, art and craft from abroad.
