Then we are told (in the verse quoted in full above) that Jagannāth prepared this excellent *Siddhānta Samrāj* for the delight of Jai Singh, and that it is a rendering into Sanskrit for the benefit of mathematicians of a work in the Arabic language entitled *Mijāsti*.¹ He also tells us² that "in the Yavana country, the Yavana masters of astronomy, Abarkhas, etc., found the maximum declination to be 23 degrees 51 minutes 19 seconds; and that in Yunan, 36 degrees north, it was found to be 23 degrees 51 minutes 15 seconds by the observations of Vitlamayus. Ulugh Beg found it to be 23 degrees 30 minutes 17 seconds at Samarqand, 39 degrees 17 minutes north. By observation with this instrument we found it to be 23 degrees at Indraprastha in 1651 Sālivāhana."
