Maharaja Jai Singh II (1699-1743) was an avid astrologer. He built the world’s largest sundial (accurate to within three seconds) and several other astrometric devices in his courtyard in Jaipur, plus three smaller copies in other cities.
There are smaller sundials aligned with particular constellations (you’ll notice azimuth and elevation angle written on the paintings)- the use of these was not clear to me, but I was intrigued by the paintings of the astrological signs : some familiar, some not.
