[INDOLOGY] Symbolic Forms of the Navagrahas

[Sudha Berry]

Dear Jacob et al,

This article may be a good start.  It is available here.
https://www.scribd.com/document/723884736/MYSTICAL-MATHEMATICS-OF-ANCIENT-PLANETS
Gupta, R.C.. (2005). Mystical Mathematics of Ancient Planets. Indian
Journal of History of Science. 40. Mystical Mathematics of Ancient Planets

While not in an academic publication, there is also an extended Reddit post
which has various illustrations of the geometrical planetary forms and a
bibliography.
https://www.reddit.com/r/IndicKnowledgeSystems/comments/1qsy7gw/the_sacred_geometry_of_celestial_bodies/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

Both articles refer to source texts, compare the Indian and Greek systems
and provide illustrations, so I trust they will take you further in your
research.

All the best,

Sudha
