[INDOLOGY] Sūrya-siddhānta critical edition?

[Jean Michel DELIRE]

Thank you very much, Lubomir, for uploading this edition, and David, for
pointing to the book, which I will certainly use for my course on History
of Indian mathematics (and astronomy).
Also for this course, I am nowadays struggling with a part of the
Lalitavistara, where the Buddha is showing his ability in numbers. His
enumeration of powers of 10, from the *koṭi *to the *tallakṣaṇa*, is very
clear. But things become obscure when he continues his enumeration with
other (supposed) powers of 10. The problem is that he says that the next
one, the *dhvajāgravatī*, is able to count all the sand of the Gaṅgā, while
the sixth one, the *sarvanikṣepa*, is able to count all the sand of ten
Gaṅgā. How is it possible if every unit equals the previous one multiplied
by ten (and what else could it be) ? Apart from noting that this kind of
enumeration and its use for counting the sand reminds very much
Archimede's Sandreckoner, I must add that there are discrepancies between
the two translations I know (de Foucaux 1988 (1884) and Goswami 2001) and
also with the 'sanskrit' text of Śāntibhikṣu Śāstrī 1984. After this
enumeration, comes a scale which rely the last unit, the
*paramāṇurajaḥpraveśānugata*, to the yojana, by multiplying it by 7 ten
times, and then again by 12, 2, 4, 1000 and 4, so that a yojana equals 710
.12.2.4.1000.4 *paramāṇurajaḥpraveśānugatas*. And, of course, the Buddha
asks if somebody can tell how many *paramāṇurajaḥpraveśānugatas* would
contain a bowl of 1 yojana. Here again, the answer seems awkward for it
amounts to 1028 while it should be more than 1041. Does anyone have an
explanation for these mistakes, or know of a paper or a book which
discusses these problems ?

Best regards,

Jean Michel
