Ajanta Caves - Architecture

Architecture

The monasteries mostly consist of vihara halls for prayer and living, which are typically rectangular with small square dormitory cells cut into the walls, and by the second period a shrine or sanctuary at the rear centred on a large staue of the Buddha, also carved from the living rock. This change reflects the movement from Hinayana to Mahāyāna Buddhism. The other type of main hall is the narrower and higher chaitya hall with a stupa as the focus at the far end, and a narrow aisle around the walls, behind a range of pillars placed close together. Other plainer rooms were for sleeping and other activities. 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 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. 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. Spink in fact 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.

The plan of Cave 1 (right) 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.

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, which reflect timber forms, and the earlier two are thought to have used actual timber ribs, which have now perished. 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. 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 painted with figures. 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, some fluted and others carved with decoration all over, as in cave 1 (illustrated left).

The flood basalt rock of the cliff, part of the Deccan Traps formed by successive volcanic eruptions at the end of the Cretaceous, is layered horizontally, and somewhat variable in quality, so the excavators had to amend their plans in places, and in places there have been collapses in the intervening centuries, as with the lost portico to cave 1. Excavation began by cutting a narrow tunnel at roof level, which was expanded downwards and outwards; the half-built vihara cave 24 shows the method. Spink believes that for the first caves of the second period the excavators had to relearn skills and techniques that had been lost in the centuries since the first period, which were then transmitted to be used at later rock-cut sites in the region, such as Ellora, and the Elephanta, Bagh, Badami and Aurangabad Caves.

The caves from the first period seem to have been paid for by a number of different patrons, with several inscriptions recording the donation of particular portions of a single cave, but according to Spink the later caves were each commissioned as a complete unit by a single patron from the local rulers or their court elites. After the death of Harisena smaller donors got their chance to add 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.

A grand gateway to the site, at the apex of the gorge's horsehoe between caves 15 and 16, was approached from the river, and is decorated with elephants on either side and a nāga, or protective snake deity.
