Introduction…
The Ajanta Caves are 30 (approximately) rock-cut Buddhist cave monuments which date from the 2nd century BCE to about 480 CE in Aurangabad district of Maharashtra state of India. The caves include paintings and rock-cut sculptures described as among the finest surviving examples of ancient Indian art, particularly expressive paintings that present emotions through gesture, pose and form.
According to UNESCO, these are masterpieces of Buddhist religious art that influenced the Indian art that followed.[6] The caves were built in two phases, the first phase starting around the 2nd century BCE, while the second phase was built around 400–650 CE, according to older accounts, or in a brief period of 460–480 CE according to later scholarship.[7] The site is a protected monument in the care of the Archaeological Survey of India,[8] and since 1983, the Ajanta Caves have been a UNESCO World Heritage

Site and monestries
The Ajanta Caves constitute ancient monasteries and worship-halls of different Buddhist traditions carved into a 75-metre (246 ft) wall of rock.[9][10] The caves also present paintings depicting the past lives and rebirths of the Buddha, pictorial tales from Aryasura’s Jatakamala, and rock-cut sculptures of Buddhist deities.[9][11][12] Textual records suggest that these caves served as a monsoon retreat for monks, as well as a resting site for merchants and pilgrims in ancient India.[9] While vivid colours and mural wall-painting were abundant in Indian history as evidenced by historical records, Caves 16, 17, 1 and 2 of Ajanta form the largest corpus of surviving ancient Indian wall-painting.[13]
The Ajanta Caves are mentioned in the memoirs of several medieval-era Chinese Buddhist travellers to India and by a Mughal-era official of Akbar era in the early 17th century.[14] They were covered by jungle until accidentally “discovered” and brought to Western attention in 1819 by a colonial British officer Captain John Smith on a tiger-hunting party.[15] The caves are in the rocky northern wall of the U-shaped gorge of the river Waghur,[16] in the Deccan plateau.[17][18] Within the gorge are a number of waterfalls, audible from outside the caves when the river is high.[19]
With the Ellora Caves, Ajanta is one of the major tourist attractions of Maharashtra. It is about 6 kilometres (3.7 miles) from Fardapur, 59 kilometres (37 miles) from the city of Jalgaon, Maharashtra, India, 104 kilometres (65 miles) from the city of Aurangabad, and 350 kilometres (220 miles) east-northeast of Mumbai.[9][20] Ajanta is 100 kilometres (62 miles) from the Ellora Caves, which contain Hindu, Jain and Buddhist caves, the last dating from a period similar to Ajanta. The Ajanta style is also found in the Ellora Caves and other sites such as the Elephanta Caves, Aurangabad Caves, Shivleni Caves and the cave temples of Karnataka.[21]

Ajanta Caves have been carved into a massive rock of the Deccan plateau. Cave 24.
The caves are carved out of flood basalt rock of a cliff, part of the Deccan Traps formed by successive volcanic eruptions at the end of the Cretaceous geological period. The rock is layered horizontally, and somewhat variable in quality.[55] This variation within the rock layers required the artists to amend their carving methods and plans in places. The inhomogeneity in the rock have also led to cracks and collapses in the centuries that followed, as with the lost portico to cave 1. Excavation began by cutting a narrow tunnel at roof level, which was expanded downwards and outwards; as evidenced by some of the incomplete caves such as the partially-built vihara caves 21 through 24 and the abandoned incomplete cave 28.[56]
The sculpture artists likely worked at both excavating the rocks and making the intricate carvings of pillars, roof, and idols; further, the sculpture and painting work inside a cave were integrated parallel tasks.[57] A grand gateway to the site was carved, at the apex of the gorge’s horseshoe between caves 15 and 16, as approached from the river, and it is decorated with elephants on either side and a nāga, or protective Naga (snake) deity.[58] Similar methods and application of artist talent is observed in other cave temples of India, such as those from Hinduism and Jainism. These include the Ellora Caves, Ghototkacha Caves, Elephanta Caves, Bagh Caves, Badami Caves, Aurangabad Caves[59] and Shivleni Caves.
The caves from the first period seem to have been paid for by a number of different patrons to gain merit, with several inscriptions recording the donation of particular portions of a single cave. The later caves were each commissioned as a complete unit by a single patron from the local rulers or their court elites, again for merit in Buddhist afterlife beliefs as evidenced by inscriptions such as those in Cave 17.[60] After the death of Harisena, smaller donors motivated by getting merit added small “shrinelets” between the caves or add statues to existing caves, and some two hundred of these “intrusive” additions were made in sculpture, with a further number of intrusive paintings, up to three hundred in cave 10 alone.[61]
Monasteries
A monastery, or vihara, with its square hall surrounded by monks’ cells. Cave 4.
The majority of the caves are vihara halls with symmetrical square plans. To each vihara hall are attached smaller square dormitory cells cut into the walls.[62] A vast majority of the caves were carved in the second period, wherein a shrine or sanctuary is appended at the rear of the cave, centred on a large statue of the Buddha, along with exuberantly detailed reliefs and deities near him as well as on the pillars and walls, all carved out of the natural rock.[63] This change reflects the shift from Hinayana to Mahāyāna Buddhism. These caves are often called monasteries.

The central square space of the interior of the viharas is defined by square columns forming a more-or-less square open area. Outside this are long rectangular aisles on each side, forming a kind of cloister. Along the side and rear walls are a number of small cells entered by a narrow doorway; these are roughly square, and have small niches on their back walls. Originally they had wooden doors.[64] The centre of the rear wall has a larger shrine-room behind, containing a large Buddha statue.
The viharas of the earlier period are much simpler, and lack shrines.[65] Spink places the change to a design with a shrine to the middle of the second period, with many caves being adapted to add a shrine in mid-excavation, or after the original phase.[66]
The plan of Cave 1 shows one of the largest viharas, but is fairly typical of the later group. Many others, such as Cave 16, lack the vestibule to the shrine, which leads straight off the main hall. Cave 6 is two viharas, one above the other, connected by internal stairs, with sanctuaries on both levels.

Worship halls

The other type of main hall architecture is the narrower rectangular plan with high arched ceiling type chaitya-griha – literally, “the house of stupa”. This hall is longitudinally divided into a nave and two narrower side aisles separated by a symmetrical row of pillars, with a stupa in the apse.[70][71] The stupa is surrounded by pillars and concentric walking space for circumambulation. Some of the caves have elaborate carved entrances, some with large windows over the door to admit light. There is often a colonnaded porch or verandah, with another space inside the doors running the width of the cave. The oldest worship halls at Ajanta were built in the 2nd to 1st century BCE, the newest ones in the late 5th century CE, and the architecture of both resembles the architecture of a Christian church, but without the crossing or chapel chevette.[72] The Ajanta Caves follow the Cathedral-style architecture found in still older rock-cut cave carvings of ancient India, such as the Lomas Rishi Cave of the Ajivikas near Gaya in Bihar dated to the 3rd century BCE.[73] These chaitya-griha are called worship or prayer halls.[74][75]
The four completed chaitya halls are caves 9 and 10 from the early period, and caves 19 and 26 from the later period of construction. All follow the typical form found elsewhere, with high ceilings and a central “nave” leading to the stupa, which is near the back, but allows walking behind it, as walking around stupas was (and remains) a common element of Buddhist worship (pradakshina). The later two have high ribbed roofs carved into the rock, which reflect timber forms,[76] and the earlier two are thought to have used actual timber ribs and are now smooth, the original wood presumed to have perished.[77] The two later halls have a rather unusual arrangement (also found in Cave 10 at Ellora) where the stupa is fronted by a large relief sculpture of the Buddha, standing in Cave 19 and seated in Cave 26.[65] Cave 29 is a late and very incomplete chaitya hall.

The form of columns in the work of the first period is very plain and un-embellished, with both chaitya halls using simple octagonal columns, which were later painted with images of the Buddha, people and monks in robes. In the second period columns were far more varied and inventive, often changing profile over their height, and with elaborate carved capitals, often spreading wide. Many columns are carved over all their surface with floral motifs and Mahayana deities, some fluted and others carved with decoration all over, as in cave 1.[79][80]
