Dear Friends,

I am looking for the ms. U 34568 (entitled Yantrarajāprayogaḥ which is a Persian text of the Risālah-i Bist Bāb dar Ma´rifat-i Usturlāb of Naṣīr al-Dīn al-Ṭūsī, transliterated in Devanāgarī) of the Library of the Varanasi Sanskrit University.

Could anyone advise me on how to see (or get a copy of) this manuscript ?

I am also looking for the edition (Bhattacarya, Bénarès, 1979) of the Sanskrit translation of the Risālah-i Bist Bāb dar Ma´rifat-i Usturlāb, entitled Yantrarāja-vicāra-viṃśādhyāyī.

Best regards,

Jean Michel Delire
