The first dated sculptures in a fully-fledged early Gupta style come from the rock-cut Udayagiri Caves and the surrounding area near Vidisha in Madhya Pradesh. Though the caves, all but one Hindu, are of negligible importance architecturally, around the cave entrances are a number of rock relief panels, some with large deities. They are in a relatively crude and heavy style, but often with a powerful impact; Harle describes the mukhalinga in Cave 4 as pulsating with psychic power. The most famous is the 7 x 4 metre relief of Vishnu in the form of the giant boar Varaha, raising the earth from the primordial waters, watched by rows of much smaller gods, sages and celestial beings. One cave also has an extremely rare inscription relating a site to the Gupta court, recording the donation of a minister of Candragupta II. The famous Iron pillar of Delhi is thought likely to have been originally set up outside the caves.
