Ajanta Ellora Caves

Way back in1819, a party of British army officers on a tiger hunt in the forest of western Deccan, suddenly spotted their prey, on the far side of a loop in the Waghora river. High up on the horseshoe- shaped cliff, the hunting party saw the tiger, silhouetted against the carved façade of a cave.
On investigating, the officers discovered a series of carved caves, each more dramatic than the other. Hewn painstakingly as monsoon retreats or varshavasas for Buddhist monks, the cave complex was continuously lived in from 200 BC to about AD650. There are thirty caves, including some unfinished ones. Of the Ajanta caves, five are chaityas or prayer halls and the rest are viharas or monasteries.
Hinayana and Mahayana

The Ajanta caves resolve themselves into two phases, separated from each other by a good four hundred years. These architectural phases coincide with the two schools of Buddhist thought, the older Hinayana school where the Buddha was represented only in symbols like the stupa, a set of footprints or a throne, and the later Mahayana sect which did not shy away from giving the Lord a human form.
Hinayana:
Among the more prominent Hinayana caves are those numbered 9, 10 (both chaityas), 8, 12, 13 and 15 (all viharas). The sculpted figures in these caves are dressed and coiffed in a manner reminiscent of the stupas at Sanchi and Barhut, indicating that they date back to the first or second century BC.
Mahayana:
The Mahayana monasteries include 1, 2, 16 and 17, while the chaityas are in caves 19 and 26. The caves, incidentally, are not numbered chronologically but in terms of access from the entrance. A terrqaced path of modern construction connects the caves, but in ancients times, each cave was accessed from the riverfront by individual staircases.
