There are no extant representations of the Buddha represented in artistic form until roughly the 2nd century CE, partly due to the prominence of aniconism in the earliest extant period of Buddhist devotional statuary and bas reliefs. A number of early discourses describe the appearance of the Buddha, and are believed to have served as a model for early depictions. In particular, the "32 signs of a Great Man" are described throughout the Pali Canon, and these are believed to have formed the basis for early representations of the Buddha. These 32 major characteristics are also supplemented by another 80 secondary characteristics (Pali:"Anubyanjana").
