This publication would not have been what it is without the help of many
institutions and people, which I acknowledge most gratefully. I thank
the Central Library and Documentation Center, Iran, and its director,
Mr. Iraji Afshar, for permission to publish photo- graphs of that part
of ms. 392 of the Shrine Library, Meshhed, containing Diocles' treatise.
I also thank the authorities of the Shrine Library, and especially Mr.
Ahmad GolchTn-Ma'anT, for their cooperation in providing photographs of
the manuscript. Mr. GolchTn- Ma'anT also sent me, most generously, a
copy of his catalogue of the astronomical and mathematical manuscripts
of the Shrine Library. I am grateful to the Chester Beatty Library,
Dublin, and the Universiteits-Bibliotheek, Leid'en, for providing me
with microfilms of manuscripts I wished to consult, and to the
Biblioteca Ambrosiana, Milan, for granting me access to its manuscripts.
The text pages in Arabic script and the Index of Technical Terms were
set by a computer-assisted phototypesetting system, using computer
programs developed at the University of Washington and a high-speed
image-generation phototypesetting device. A continuous stream of text on
punched cards was fed through the Katib formatting program, which broke
up the text into lines and pages and arranged the section numbers and
apparatus on each page. Output from Katib was fed through the compositor
program Hattat to create a magnetic tape for use on the VideoComp
phototypesetter.
