The current range of postures in which the Buddha may be shown, and the gestures which may be depicted, evolved over the first millennium of the Buddhist era (roughly 500 BCE to 500 CE), mainly in India, the original homeland of Buddhism. The tradition of images that reached South-East Asia had been changed in the later 5th century CE, apparently first at Sarnath in India. The new "Sarnath image type" or "Gupta period Buddhist image" differs from earlier Buddha images, such as those in Greco-Buddhist art, in a number of respects: the gaze is lowered, the clinging robes disclose no male genital bulge, the robe lacks folds, and there are different body proportions.
