Explanation:

 1. Some of Ajanta caves have been painted with scenes from Jainism. ( only Buddhism related)
2. The Ajanta caves have been built over a period of eight centuries mainly by Pallava rulers. (caves have been built over a huge time slice of history, starting from about 200 BCE till around 480-650 CE. )
Ajanta caves have enjoyed two distinct phases of patronage:

• The early Hinayana Buddhist phase, mostly under the patronage of Satvahana Dynasty
The caves 9,10,12,13 and 15A were excavated during this period and thus form the oldest part of the great complex at Ajanta.
These caves are relatively simple and astylar in their architectural construct, do not penetrate much into the rock surface and were mostly dormitories for Buddhist monks.
The decline of Buddhism in India also witnessed inactivity in Ajanta for almost 3
centuries. The dormancy gave way to a remarkable renaissance from 460 CE onwards.

• The Mahayana Buddhist phase, spearheaded by Vakataka Dynasty (particularly by Emperor Harisena)
Emperor Harisen (Not to be confused with Harisen – the royal poet to the court of Emperor Samudragupta) was a powerful Vakataka king whose short reign (460-477 CE) was characterised not only by military advances and forging of a great empire but also for reviving a strong cultural movement. He was a connoisseur of art and architecture in a multi-religious context.
