This is the earliest surviving vihuela music. It is copied into the endpapers of a copy of Lucius Marineus Siculus, Epistolarum familiarum (Valladolid, 1514) held in the British Library [GB-Lbl], call number C.48.h.1. This work was brought to the attention of Tess Knighton who passed it on to Antonio Corona-Alcalde, resulting in an article published in Early Music in 1992 [corona1992]. Corona-Alcalde suggests 1520-1536 as the possible composition or copying date. The notation shares certain common features with the Baena keyboard tablature.
