Tirupur: A few archaeological enthusiasts have recently discovered an 800-year-old Ayyanar carving at Erakarampatti village near Kundadam in the district. “Rajakesari Peruvazhi, an ancient trade route, was connecting the western port city Muziri Pattanam of Malabar and the eastern coastal city Poompuhar (present Nagapattinam). It means his right leg was folded horizontally while the left leg was folded vertically. His left hand was placed on the mounting knee of the left leg. Erakampatti was falling in the same route, which was one of three major ancient trade routes,” he mentioned..
