Abū al-Fath Abd al-Rahman Mansūr al-Khāzini or simply al-Khāzini (أبوالفتح عبدالرحمن منصور الخازنی (Persian), flourished 1115–1130) was an Iranian astronomer of Byzantine origin who lived during the Seljuk Empire.[1][2][3][4] His astronomical tables written under the patronage of Sultan Sanjar (Zīj al-Sanjarī, 1115) is considered to be one of the major works in mathematical astronomy of the medieval period.[5]: 107 He provided the positions of fixed stars, and for oblique ascensions and time-equations for the latitude of Marv in which he was based.[6]: 197 He also wrote extensively on various calendrical systems and on the various manipulations of the calendars.[5] Al-Khazini was the author of an encyclopedia on scales and water-balances called The Book of the Balance of Wisdom (Kitab Mizan al-Hikmah, 1121), which explored theories of density, specific gravities of metals, precious stones, and liquids, as well as principles of equilibrium.[7][8]
