[INDOLOGY] Inquiry on Equatorium and Planetary Diagrams in Sanskrit Sources

[Jean Michel DELIRE]

Of course, Sarma's Catalogue,

The photos I sent show an instrument imported from France to Jaipur (or
somewhere in India first). It is conserved in the Museum of the Observatory.
This shows Jai Singh II's interest (or his son Madho Singh's interest) for
this instrument. I have never seen any Sanskrit text on it, at least in
Jaipur.

Best,
