"Dr. Nagaswamy, in The Hindu article “Testimony of Religious Ethos”, mentions the findings of Buddhist relics and a mutilated Buddha image in Mylapore.

They include St. Peter’s, Santa Maria Maggiore and Santa Maria Rotunda (The Pantheon) in Rome, Notre Dame in Paris, and St. Paul’s in London. St. Benedict built his monastery on an Apollo temple that he had destroyed himself, at Monte Cassino, Italy. The much revered Black Virgins found in churches and monasteries in Spain and Italy are images of the Egyptian Goddess Isis and Her son Horus. The list is very long. 56. These are at Malinkara, Parur, Gokamangalam, Niranam, Chayal and Kurakonikollam in Kerala, and Tiruvithancodu in Tamil Nadu (this being the “half church”, which is a converted Hindu temple)."
