The Guitarra morisca or Mandora medieval is a plucked string instrument.
Part of that characterization comes from a c. 1330 poem, Libro de buen amor by Juan Ruiz, arcipestre de Hita, which described the "Moorish gittern" as "corpulent".
It has similarities to both the guitarra latina and medieval lute, usually played by fingers or plectrum.
It has roots in the four-string Arabic oud, brought to Iberia by the Moors in the 8th century.
Early instrument expert Francis William Galpin mentioned the instrument in his book, Old English Instruments of Music (pages 21-22), calling it the "Guitare Moresca" or "Chittara Saraacenica", with its "long neck, oval shaped body and round back."
