An early 20th century Arabic manuscript of the "Sphaerics" by the Greek astronomer and mathematician Theodosius of Bithynia (ca. 169-100 BCE). Unknown in the West during the Middle Ages, the "Sphaerics" proved instrumental in the restoration of Euclidean geometry to Western civilization when the book was brought back from the Islamic world during the crusades and translated from Arabic into Latin.
The present manuscript was written in Afghanistan under the rule of Habibullah Khan, a reform-minded Emir who attempted to introduce modern medicine and other technology to his country. The prettily blindstamped binding would also appear to be of Afghan origin.
Paper a little browned and brittle; traces of former block-stitching; some of the first few leaves transposed during re-binding, according to the later ballpoint pagination.
