The width of this frieze suggests that it was probably intended as decoration for a building. Considering that the majority of extant Gandharan art focuses on the Buddha, it is likely that this frieze came from a wider scene which depicted the religious leader. Gandharan art was heavily influenced by the expansion of Hellenistic culture, and statues and friezes often display influences from Greek art. The stylised arches and capitals are evidence of such influence here.
