This is the first English translation of first three out of the 7 volumes of the fundamental work on optics by the medieval Arab scientist Ibn al-Haitham or Alhazen (965–c1039). His book exerted a great influence upon science through Witelo, Roger Bacon, Peckham and Kepler. Alhazen investigated many particular cases of reflection and refraction, and drew attention to the light-ray’s property of retracing its path when reversed. He was the first to give a detailed description of the human eye and to study binocular vision. Certain ophthalmological terms originated from the Latin translation of Alhazen’s Arabic text, e.g. retina and cornea.
The Book of Optics (Kitāb al-Manāẓir, كتاب المناظر) presented experimentally founded arguments against the widely held extramission theory of vision (as held by Euclid in his Optica) and in favour of intromission theory, as supported by thinkers such as Aristotle, the now accepted model that vision takes place by light entering the eye.
Part 1 contains the translation; Part 2 an introduction, commentary, Arabic-Latin glossaries, concordance, bibliography, and indices.
Edition of the Arabic text, edited by A. I. Sabra, was published by National Council for Culture, Arts and Letters, Kuwait, in 1983 (Books I-III) and 2002 (Books IV-V). Sabra’s translation of the latter has not yet been published.

This major work fills a major lacuna in the literature by bringing together for the first time all of the projects, realizations and texts related to architecture by the multi-faceted Xenakis who worked with Le Corbusier for 12 years. Sharon Kanach assisted the composer in gathering the texts for this his last ambitious project.
The material in the book is presented under four main headings: “The Le Corbusier Years”, “Xenakis as Independent Architect”, “Writings on Architecture”, and “The Polytopes”. Three annexes include a commented bibliography of writings by and on Xenakis compiled by Makis Solomo, a critical index of Xenakis’s architecture by Sven Sterken, and a comparative chronology of Xenakis’s life and work by Sharon Kanach. The latter’s commentary throughout the book strives to bridge the reciprocal influences between music and architecture in the Xenakis oeuvre.

Telehor was a project by Czech functionalist architect, theorist and educator, František Kalivoda, who planned it as a 64-page illustrated quarterly dedicated to visual culture. As an editor and publisher, Kalivoda had established an impressive network of collaborators across Europe, however his plans never fully took off.
Its only issue appeared as a book-length publication on the work of artist and Bauhaus teacher László Moholy-Nagy who was at the time already living in London. The magazine has, in the internationalist fashion, sections in several languages, including French, English, Czech, and German.
Contents of the English section: Foreword by Siegfried Giedion, 1935 (pp 27-29), Letter from Moholy-Nagy to Kalivoda, June 1934 (30-32), Moholy-Nagy’s essays “From Pigment to Light”, 1923-26 (32-34), “A New Instrument of Vision”, 1932 (34-36), “Problems of the Modern Film”, 1928-30 (37-40), “Supplementary Remarks on the Sound and Colour Film”, 1935 (41-42), “Once a Chicken, Always a Chicken”, a film script on a motif from Kurt Schwitter’s “Auguste Bolte”, 1925-30 (43-45), Postscript by Kalivoda, 1936 (45-46).
The reproductions run from page 49 through 112.
