Geography of the Rigveda, with river names; the extent of the Swat and Cemetery H cultures are also indicated. The Rigveda is far more archaic than any other Indo-Aryan text. Writing appears in India around the 3rd century BC in the form of the Brahmi script. The Rigveda describes a mobile, semi-nomadic culture, with horse-drawn chariots, oxen-drawn wagons, and metal (bronze) weapons. The geography described is consistent with that of the Greater Punjab.
