THE HISTORIC cry of Talakad, situated on the north bank of the Kaveri river, now lies partly buried under shifting sand dunes. From the 5th to the 10th centuries it was the capital of the Gangs dynasty but only two modest temples survive from that period. The largest edifice at this site is the 12th-century Vaidyeshvara Temple, dedicated to Shiva. Nearby is the more modest Kirti Narayana Temple, where the 3-m (10-ft) high image of Vishnu is still worshipped. A festival, the Panchalinga Darshana, is celebrated here at intervals ranging from four to 12 years.
