The Colisvara temple is the smaller of the two shrines of the Avani-Kandrapa-Isvaram temple built at Kilaiyur under Aditya I (871-907 CE). The other one is the Agastisvara shrine. Colisvara is a double storied stone shrine. The crowning cupola (shikhara) is circular and bell-shaped with a fine finial (stupi) over it unlike the square shikhara and stupi of its twin shrine making this a unique feature of the Avani-Kandrapa-Isvaram temple at Kilaiyur.

Dayanidhisvara temple, Aduthurai, Tamil Nadu

The Divyajnanesvara temple at Aduthurai was built in Gandaraditya's third regnal year i.e. 952 CE. It is relatively small with only traces of decoration on the vase shaped pillar part (lasuna) of its pilasters. It stands on a simple platform (upapitha) and the door guardians (dvarapalas) are smaller than usual but of good workmanship. All pillars and pilasters are of the full Early Chola order with plain angular corbels. References: M.W. Meister and M.A. Dhaky, 1963, p.176, D. Barrett, 1973, p. 85.

Gangaikondacolisvaram, Siva temple at Kulampandal is of the time Rajendra Chola built some time before his twenty-second year - 1034 CE. The temple is said to have been built by Isana-Siva Pandita, a preceptor of Rajaraja I (985 - 1014 CE) as well as of Rajendra I (1014 – 1044 CE). Reference: M.W. Meister and M.A. Dhaky, 1963, pp. 232-234.

The Ghritasthanesvara temple at Tillaisthanam is perhaps the latest amongst Muttaraiyar buildings; it ushers in features that are seen in typically Chola temples. For example, the bulls over the prati-corners show a transition toward Chola types. There are some stray sculptures of Muttaraiyar workmanship including an earlier Nandi in the temple’s surroundings. Three important inscriptions are associated with this temple. The oldest, perhaps of the brother of Maranjadaiyan Varaguna II, is one of the monarch’s fourth year (866 CE), the second is in the tenth year of a Pandya king inscribed by one Pallava Nandivarma. The third, of the eighth year of Rajakesarivarma (879 CE) that records a donation by Aditya I’s son. These inscriptions give clear evidence of the transfer of power over this region from the Pallava to the Pandya and then to the Chola rulers. The temple seems either pre-Chola or rebuilt in 878-879 CE. And if the builders were indeed Chola, then they must have tried to follow the convention of an older Muttaraiyar building. Reference: M.W.
