Ibn Al-Haytham's "Completion of the Conics"

This book is a revised and slightly augmented version of my doctoral dissertation (Utrecht 1983). The Subfaculty of Mathematics of the Rijksuniversiteit Utrecht gener ously enabled me to pursue the necessary research. I thank Prof. Dr. F. van der Blij for his interest in my work and for his many stimulating questions and remarks. The discussions with Dr. Henk Bos and his criticisms of earlier drafts have resulted in essential improvements in method and style. Prof. Gerald Toomer (Brown University) suggested the topic of the thesis and assisted in all stages of its preparation, even at the expense of his own research. He discussed the entire Arabic text and the English translation with me during my visit to Providence (1981), which was financially sup ported by the Netherlands Organization for the Advancement of Pure Research (Z. W. O. ). I wish to express my sincerest thanks to Dr. Remke Kruk for teaching me to read Arabic manuscripts, and for constant advice and encouragement in the past nine years. I am grateful to Prof. Dr. H. Daiber (Vrije Universiteit, Amsterdam) for a number of valuable remarks and suggestions in philological matters. My colleagues Jan van Maanen (Utrecht) al1~_ ~r. Len Berggren (Vancouver) read large parts of the thesis with meticulous care and suggested many improvements. All errors and inad equacies that remain are entirely my own. Thanks are due to Dr. J.
