"These crosses may be evidence of the connection of the Christian church in India with Persia, but they may also be evidence of temple destruction and the planting of Christian relics in temple foundations – at least the one on St. Thomas Mount may be so considered. The motif on this black granite slab is cut in relief, and on each side of the cross, which is surmounted by a descending dove, are pillars crowned with supernatural composite animals, or yalis, from whose mouths issue an arch that joins together above the dove. These yalis are Hindu symbols, not Christian, and Veda Prakash, Director of the Institute for the Study of Western Religions, Madras, asserts that the cross on St. Thomas Mount is an over-cut temple stone. He claims support for this view from the most unexpected quarter. Dr. R. Arulappa, the former Roman Catholic archbishop of Madras, in Punitha Thomaiyar, says that yantra stones in temple foundations were dug up by the Portuguese at three of the four sites in Madras that they associated with St. Thomas and where they built churches – Mylapore, Little Mount at Saidapet, and Big Mount at St. Thomas Mount."
