"The earliest records of the Madras area, including money-lenders' accounts, go back to the fourth century CE. They identify Mylapore, Triplicane and Tiruvottiyur as temple towns. The Nandikkalambakkam describes Mylapore as a prosperous port under the Pallavas, the early-fourth- to-late-ninth century emperors of Kanchipuram, who patronized various schools of Hinduism including Jainism and Buddhism, built temples and generously supported the arts. There is no record of a Christian church or saint's tomb at Mylapore before the Portuguese period, and Olschki is basing his comments on the wrong assumption that Marco Polo did visit Mylapore and that he found a church there. Friar Oderic is describing the original Kapaleeswara Shiva Temple on the Mylapore seashore (see Henry Yule's comment: "This is clearly a Hindu temple."), which the Tamil saint Jnanasambandar has positively identified as being there at least before the sixth century CE."
