There seem to be some errors in the content of the album. Swami Sir study notes can be easily referenced - especially the reference to the inscription in sittanavasal as that of Mahendra Varman is not correct- some errors in the inphoto labels - like Vatteluthu in 8 -9 C CE. 22000 years ( typo one more zero).
Request to be more diligent especially when we want to promote correct knowledge about our history and sites
