In the early summer of 1819, a British hunting party was heading through thick jungle near Aurangabad, in Maharashtra, western India, when the tiger they were tracking disappeared into a deep ravine. Leading the hunters was Captain John Smith, a young cavalry officer from Madras. Beckoning his friends to follow, he tracked the animal down a semi-circular scarp of steep basalt, and hopped across the rocky bed of the Wagora river, then made his way up through the bushes at the far side of the amphitheatre of cliffs. Halfway up, Smith stopped in his tracks. The footprints led straight past an opening in the rock face. But the cavity was clearly not a natural cave or a river-cut grotto. Instead, despite the long grass, the all-encroaching creepers and thorny undergrowth, Smith was looking at a manmade facade cut straight into the rockface. The jagged slope had been painstakingly carved away into a perfect portico. It was clearly a work of great sophistication. Equally clearly, it had been abandoned for centuries.
