The earliest Indian art comes from the Stone Age, starting about 4500 BC. People arriving from West Asia about this time brought their art ideas with them, and they made small clay figurines of women that look a lot like Sumerian figurines from about the same time. Like Sumerian figurines, the clay figurines from Mehrgahr have hooked, pointed noses, big inset eyes, and big curly hair. They hold their arms folded in front of them (or they would, if their arms weren’t broken off).
But they’re also very different from the Sumerian figurines. The Mehrgahr figurines are all women, they’re nude, and they have big, high, round breasts. These are features that become common in later Indian art.
