From the eighth to the tenth century A.D., Greek scientific and philosophical works were translated wholesale into Arabic. A Greek and Arabic Lexicon is the first systematic attempt to present in an analytical and rationalized way our knowledge of the vocabulary of the translations. It is based on the glossaries included in text editions, both published and unpublished, and on other materials gleaned from various sources. The work is published in 7 fascicles of 128 pages each. The work is published in fascicules of 128 pages of lexical entries plus indexes of the Greek-Arabic correspondences, of Greek proper names and transliterated words, of variant Greek and Arabic passages, and of the Greek authors cited in the context passages.
