T.S. Subramanian (10. 7. 2009). „Jain History of Tamil Nadu vandalised”. Приступљено 3. 6. 2011. „The six Tamil-Brahmi inscriptions of the 2nd century B.C. on the brow of five caverns on the Kazhugumalai hill near Mankulam, 38 km from Madurai, are the most ancient ones in Tamil Nadu and establish the historical facts that the Pandyan king Nedunchezhiyan ruled in the 2nd century B.C. and that Sangam literature dates back to the same period.”
