Unfortunately we possess no exact descriptions of the Persian and Arabian instruments between the tenth and fourteenth centuries, otherwise we should probably have earlier accounts of some instrument of the violin kind in Persia. Ash-shakandi, who lived in Spain about A.D. 1200, mentions the rebab, which may have been in use for centuries without having been thought worthy of notice on account of its rudeness. Persian writers of the fourteenth century speak of two instruments of the violin class, viz., the rebab and the kemangeh. As regards the kemangeh, the Arabs themselves assert that they obtained it from Persia, and their statement appears all the more worthy of belief from the fact that both names, rebab and kemangeh, are originally Persian. We engrave the rebab from an example at South Kensington.
