From Booklist, on the English Version:

A historian of science, Freely chronicles the transmission of scientific ideas from ancient Greece and Rome to an early modern Europe on the cusp of the scientific revolution. Many ancients' notions about nature were, Freely recounts, preserved from oblivion by scholars based in centers of Islamic learning such as Baghdad, Cairo, and Cordoba. Before reaching those destinations, Freely profiles the Greek sages, enumerating their surviving works and what information they held about mathematics, astronomy, and medicine, among other subjects. Leaving behind a roster of names that is likely familiar to the core audience, Freely's account then addresses Islamic rulers, such as the first caliphs of the Abbasid dynasty around 800, who sponsored translations into Arabic of Greek texts. Freely ranges over the names of Islamic scholars so occupied, who served as arks for Greek science, and of original thinkers who formulated such topics as algebra, all of which reached the West in the cultural diffusion Freely describes. A sinuous odyssey through scientific ideas, Freely's work will most appeal to tastes for intellectual history. --Gilbert Taylor
