Temple architecture in South India reached its pinnacles under the rule of imperial Cholas (850 – 1250). Early Chola temples however, are not as large as the ambitiously planned Pallava Kailashnatha or the Vaikunthaperumal temples at Kanchipuram. Development in early Chola architecture consists, instead, in perfecting the unique elements of the Dravidian style and combining them harmoniously with new forms in astonishingly diverse ways.
A typical new Chola feature, that is different from the Pallava, is the famed ornamentation of temple walls. This consists in the use of real deep niches with entablatures. These niches, the Devakushtas (niches to house deities), flanked by demi pilasters, appear on wall surfaces of Chola temples. The decoration, in most finished examples, alternates between the various niche devices of koshtapanjaras and Kumbhapanjaras. Space is narrow in these forms but the decoration is more rounded. The pilasters of these niches are crowned by a curved roof moulding adorned by two kudus with crowning lion heads. The bases of these decorative devices have makara (motif based on the mythical sea monster) and warrior heads.
Other Chola distinction is seen in the abandonment of the Pallava yali or the lion at the bases of pillars and pilasters. The pillars too, are more enriched and defined. As earlier noted, the final element in the Dravidian pillar of the notch in the shaft before it flares, with a slight swelling above it, gets transformed now under the Cholas to become the most delicate of vases (kalash). Another elegant feature of the pillar is the decorative device of the kudu, put as a roll-moulding on top of the pillars.
The gateways, which are dwarfed in the Pallava, are in late Chola prominent. Thedwarpalas(gatekeepers) in Chola temples are fierce men with tridents, bearing tusks protruding from mouths, rolled eyes and hands always in threatening gestures. These contrast with the benign natural looking single paired arm dwarpalas of the past. All these features climax in two temples, the Brihadisvara (Rajarajesvara) at Thanjavur, the capital of the Cholas and the Gangaikondacholapuram, near Kumbakonam. These come at a time of greatest extent of Chola power.
Cholas had become the greatest power in South India by 10thcentury CE. They had reached the borders of the Rashtrakuta kingdom in the north. Rows of temples were built on both the banks of the river Kaveri to mark their growing power. Cholas greatly made use of art to proclaim their power, used temples to make unequivocal statements about their political hegemony. Rajaraja I, crowned in 985, carved out an overseas empire by establishing a second capital at Pollonaruva in Sri Lanka. The Brihadisvara (995 – 1010), built by him at his capital Thanjavur, though he did not live to see it completed is a product of this success. The temple inscriptions make clear the triumphal nature of the edifice. Donations to the shrine came from far and wide. The numbers of architects, accountants, guards, functionaries, temple dancers, revenue records of landgrants etc are engraved on the temple walls, thus establishing the importance of the temple as an institution of prime importance in Chola times.
The Brihadisvara is some 210 feet High, the largest and the tallest in India. It is laid out as a Dravida padmagarbhamandala of 16 into 16 squares. It was consecrated in 1009 – 10. The site is not associated with any Puranic story or any ancient legend, the Rajarajesvara appears to have been an entirely new foundation, a royal monument of power. Within the large enclosure wall are shrines of theparivardevatas(family deities) and thedikpalas(deities of cardinal directions). The eight dikpalas are housed separately against the wall. The two large gopuras in line are first introduced here in Dravidian architecture. The vimana is dvitala (double storied).
The vertical base (a square of 82 feet with a height of 50 feet) forms the first storey and the 13 slightly receding tiers form the upper portion. The diminishing tiers taper till the last at the apex to become one third of the base. On top of this rests the crowning dome, which comprises a massive granite block of 25 and a half feet square and estimated to weigh eighty tons. The cupola with its inward curve of its neck is a pleasing break from the outward rigid lines of the composition that has a soaring character.
An internal circumambulatory passage, two stories high, consisting of a series of chambers with sills but no doors, runs inside the precinct. On its walls, in 1930, Nayaka period paintings were discovered to overlay the Chola murals that included Rajaraja I with three of his queens worshipping Nataraja (dancing Shiva), the patron deity of Cholas. The temple is entered by side doorways approached by large ornamental stairs leading to an antechamber (ardhmandapa), with a platform for bathing the deities. To it is attached a huge mandapa of 36 pillars (mahamandapa), entered by a front mandapa with a central entrance (mukhamandapa). In all there are 18 door guardians flanking the various entrances and sills.
In the decorative treatment, the lower vertical base is of two stories divided by a massive overhanging cornice, reminiscent of the Pallava rock-cut. Except for this powerful horizontal member in the structure, the emphasis is on verticality, the two ranges of vertical pilasters above and below adding to the verticality. Combined with these pilasters are deep niches with motifs of ‘tree of knowledge’ and other decorative devices. Occupying the middle of each compartment, are ingeniously carved figures. The kumbhapanjara decorative device is introduced here. The surfaces of the tapering part of thevimanaare patterned by the horizontal lines of the diminishing tiers intersecting the vertical disposition of the ornamental shrines, thus producing a very rich architectural texture. Finally, there is the contrast of the cupola at the summit, its winged niches on all four sides relieving the severity of the outline, just where it is most required.
Every section and every decoration at the Brihadisvara is designed for maximum effect. It is the finest example of Dravidian architecture with all its elements reaching their zenith.
