Dear friends,

With thanks to those who corresponded with me about my puzzle, I have found an alternative solution, though one that involves another, perhaps lesser puzzle. 

The syllable preceding ṣāstriṃśat in my text is ca, which I had taken to be a conjuction. But if  we read caṣās triṃśat, "thirty caṣās," and take caṣa to be a contraction of caṣaka, then this would be mathematically appropriate in context (roughly, "thirty minutes in a half-hour"). However, I have not been able to find an attestation of caṣa for caṣaka. Has anyone seen this before?

many thanks,
Matthew

Dear friends,

An astrological text I am studying contains the word
ṣāstriṃśat
which has me stumped. Perhaps it is a very odd way of representing 36, ṣaṭtriṃśat
but this strikes me as quite strange.
The reading is confrimed, however, by all four manuscripts that I am consulting, although they often disagree about other matters. 

I would welcome your learned suggestions.

thanks in advance,
Matthew
