Ruiz de Ribayaz accompanied the new Spanish viceroy on his journey to Peru in 1667, but returned to Madrid some time before the publication of a harp and guitar manual, Luz, y norte musical, para caminar por las cifras de la guitarra españióla, y arpa (Madrid, 1677).[1] The publication was endorsed by no less than Cristóbal Galán, maestro de capilla of the Convent of Las Descalzas Reales.[2]
