Aniconism in Buddhism
Since the beginning of the serious study of the history of Buddhist art in the 1890s, the earliest phase, lasting until the 1st century CE, has been described as aniconic; the Buddha was only represented through symbols such as an empty throne, Bodhi tree, a riderless horse (at Sanchi), Buddha's footprints, and the dharma wheel. This reluctance towards anthropomorphic representations of the Buddha, and the sophisticated development of aniconic symbols to avoid it (even in narrative scenes where other human figures would appear), seem to be connected to one of the Buddha's sayings, reported in the Digha Nikaya, that discouraged representations of himself after the extinction of his body. Although there is still some debate, the first anthropomorphic representations of the Buddha himself are often considered a result of the Greco-Buddhist interaction, in particular in Gandharaa theory first fully expounded by Alfred A. Foucher, but criticised from the start by Ananda Coomaraswamy. Foucher also accounted for the origins of the aniconic symbols themselves in small souvenirs carried away from the main pilgrimage sites and so becoming recognised and popularized as symbolic of the events associated with the site. Other explanations were that it was inappropriate to represent one who had attained nirvana.
However, in 1990, the notion of aniconism in Buddhism was challenged by Susan Huntington, initiating a vigorous debate among specialists that still continues. She sees many early scenes claimed to be aniconic as in fact not depicting scenes from the life of the Buddha, but worship of cetiya (relics) or re-enactments by devotees at the places where these scenes occurred. Thus the image of the empty throne shows an actual relic-throne at Bodh Gaya or elsewhere. She points out that there is only one indirect reference for a specific aniconic doctrine in Buddhism to be found, and that pertaining to only one sect. As for the archeological evidence, it shows some anthropomorphic sculptures of Buddha actually existing during the supposedly aniconic period, which ended during the 1st century CE. Huntington also rejects the association of "aniconic" and "iconic" art with an emerging division between Theravada and Mahayana Buddhism. Huntington's views have been challenged by Vidya Dehejia and others. Although some earlier examples have been found in recent years, it is common ground that the large free-standing iconic images of the Buddha so prominent in later Buddhist art are not found in the earliest period; discussion is focused on smaller figures in relief panels, conventionally considered to represent scenes from the life of the Buddha, and now re-interpreted by Huntington and her supporters.
In later periods both the major schools of Buddhism have made great use of representational art, though Theravada temples and other sites typically concentrate on a single large sculpture of the Buddha, whereas Mahayana temples have larger numbers of images of a greater variety of figures with varying degrees of spiritual significance. However some schools, such as Zen Buddhism in Japan, have also shown a general tendency towards aniconism, though without specific prohibition of figurative images.
