Page and line citations are to Volume One of this work unless otherwise noted. A most welcome development in al-Kindi studies is the series edited by Roshdi Rashed and Jean Jolivet,Oeuvres Philosophiques & Scientifiques d'al-Kind i, appearing with Brill in five volumes. As yet, only the first two have appeared (Volume One:L'Optique et la Catoptrique [Leiden: Brill, 1997], Volume Two:Métaphysique et Cosmologie [Leiden: Brill, 1998]).

But as the Arabic texts provided in this series will undoubtedly be the standard edition in the future, I will give additional page and line citations to Volume Two of this series where applicable, marked in brackets and with the abbreviation RJ. [^5]:R. fi kammiyya Kutub Aristutalis wa ma yuhtaju ilayhi fi tahsil al-falsafa (On the Quantity of the Books of Aristotle and What is Required for the Attainment of Philosophy ), Abu Rida, 363-84 at 384.9.

[^6]: The Arabic text for the Theology and other parts of the Arabic Plotinus is in Aflutin 'inda 'l-'Arab , A. Badawi, ed. (Cairo: 1955). Translations are my own, but for the reader's convenience section numbers are taken from G. Lewis's English translation in Plotini Opera , P. Henry and H.-R. Schwyzer (Paris: Desclée de Brouwer, 1959), vol. 2.

I also give references to Badawi's edition by page and line numbers in brackets prefaced by "B." Thus, for example, the passage just quoted is Prologue 11 and 14 [B 6.1 and 6.7-8]. For an argument aimed at showing that al-Kindi was the author of the Prologue to the Theology , see C. D'Ancona Costa, "Al-Kindi on the Subject Matter of the First Philosophy. Direct and Indirect Sources of 'Falsafa-l-Ula,' Chapter One," inWas ist Philosophie im Mittelalter , J. A. Aertsen and A.

Speer, eds., Miscellanea Mediaevalia (Berlin: Walter de Gruyter, 1998), 841-55. [^7]: For the Arabic text, see O. Bardenhewer,Die pseudo-aristotelische Schrift über das reine Gute (Frankfurt a.M.: Minerva, 1882). The best English translation currently available can be found in St. Thomas Aquinas,Commentary on the Book of Causes , Guagliardo et al., trans. (Washington, D.C.: Catholic University Press, 1996).

[^8]: It is now well established that three separate texts represent an original, united Arabic Plotinus paraphrase: theUthulujiyya (Theology of Aristotle ); theSayings of the Greek Sage , which assembles various texts attributed to "the Greek Sage" (al-Shaykh al-Yunan i); and the pseudo-FarabianR. fi 'l-'Ilm al-Ilahi (Letter on Divine Science ).
