1) Can someone point me to some article on when and why the Rg-veda was first written down . what script etc.  Was it a British initiative or was the whole or parts written down before the colonial period?  I've seen in a modern Taittiriya Vedashala the students practicing some of their mantras using  written material.  Did the medieval and later Vedashalas also use written materials to teach their students?

2) Is it possible that this  "Rg-veda written spelling gachati etc." is just a reflection of what was written when the Rg-veda was first written down?

Thanks,

Harry Spier
