Note 96 — Chapter X
David Shea translation
This is a work of Naśer eddin Túsi (about whom, see vol. II. p. 417, note 2, and p. 449). He was the favorite minister of Hulagu Khan, whose arms he had successfully directed against Baghdad and the Khalif. The Khan, after his conquests, took up his residence at Maragha, in Aderbigan; there he assembled philosophers and astronomers to cultivate science, under the direction of Nâśer eddin. In our days the place is still shown where the observatory of this astronomer was situated, and where he compiled the astronomic tables, known under the name of Jal-khanní.
