Indian Art History
May 2016 - The major themes of Indian art seem to begin emerging as early as the Harappan period, about 2500 BC. Although we're still not sure, some Harappan images look like later images of Vishnu and Shiva, and the tradition may start this early.
Around 500 BC, the conversion to Buddhism of a large part of the population of India brought with it some new artistic themes. But at first nobody made images of the Buddha - only stupas (STOO-pahs), symbolic representations that didn't look like a person.
Then the conquests of Alexander the Great, in the 320s BC, also had an important impact on Indian art. Alexander left colonies of Greek veteran soldiers in Afghanistan and Pakistan, and these soldiers attracted Greek sculptors (maybe some of the soldiers were sculptors). Their Greek-style carvings attracted attention in India - the first life-size stone statues in India date to the 200s BC, just after Alexander.
During the Guptan period, about 500 AD, the rise of the Silk Road and increasing trade with East Africa brought a lot of wealth to India. With that money, artists carved the great cave temples of Ajanta and Ellora. Scenes from the life of the Buddha became popular, and statues of the Buddha.
Finally, the arrival of the Islamic faith and Islamic conquerors about 1000 AD brought iconoclasm to India, and a love of varied and complex patterning derived from Arabic and Iranian models. This affected even Hindu artists who had not converted to Islam. Small Iranian-style miniature paintings also became popular.
