King&J. SaffiSÓ 1 Introduction The purpose of this paperl is to present an overview of the current state of research on the medievallslamic astronomical handbooks known as lijes in panicular,2 and aSlronomical tables in general. It is intended as a supple ment lO E. S. Kennedy's groundbreaking survey of Islamic lijes published in 1956,3 incorporating lhe numerous categories of tables nol contained in lljes,4 and an atlempt has been made to mention most of lhe research !hat has been done since lhat lime.~ It is also ¡ntended as an inlerim overview 1lle maio authors (D.A.K. aOO J.S.) are gralefullo Fra~is Charelle. Renno van Dalen. Remard Goldstein aOO David Pingree foc lheir eommenlS on earlier versions of Ihis p3per, lmd are alone responsible for any remaining errors aOO misinlerprelations. We are panicularly pleased thal 8emard Goldstein was wil1ing lO conlribute an important chapter on Hebrew tijes. 8ibliographical abbrcviations for lhe basic reference works for lhe hislOry of Islamic aslronomy aOO malhemalics aOO other frequenliy-ciled works are lislcd allhc cm! of this papero 2 11IC tcrm zij is Iraditionally dcrived from Pahlevi zik, origillally meaning 'thread' or 'cord' and already uscd in Pahlevi wilh the meaning 'astronomicaltables'.I'resumably by exlension oflhe notion ofa thread lO lhe warp of a fabrie and henee lO the orthogonal framework of an aslronomieal table (Kennedy, "al Survey". p. 123b, ciling C. A. Nallino). However. recent research suggests lhallhe lerm was originally used in Arabie lO denote an asln)llOmical lext in verse. as in Sanskril tanlm, without any tables: see funher R. Mercier. "From Tantra lO Zir, in Kunirzsch Festschrift, pp. 451-460. , Kennedy, "al survey". See also SaffiSÓ. "Tablas astronómicas". • A preliminary survey was presented in King. "Islamic Aslronomical Tables". , 1lle firsl version of this paper was prepared in answer lO a requesl for an article ''Zidj'' for lhe E/2. It tumed out to be far longer Ihan Ihe Edilors could accept, so we de cided to prepare this version, reformatting the firsl for lhis joumal, suppressing all of the quirky features of the E/2 (nolably, lhe lranslileralion). but retaining mosl of the eross·refercnees to other anicles on specific topies in Ihat monumental work (hcre cap· italized, as, for example: zt.Ql). We have, on Ihe olher hand, suppressed referenees lO anides on individual astronomers in E¡2 aOO DSB. We assume on the pan of lhe reader a certain familiarilY with lhese works, as well as with lhe standard bio-bibliographical sources. namely (in chronological order): SUler, MAA; Renaud, "Addilions l Suter": Krause, "Stambuler Handschriften"; Storey, PL; $ezgio.
