Orlando Furioso
Orlando furioso RV 819 (Teatro San Angelo, Venice 1714) is an opera surviving in manuscript in Vivaldi's personal library, only partly related to his better known Orlando furioso (RV 728) of 1727. It is a recomposition of an Orlando furioso written by Giovanni Alberto Ristori in 1713, whose score survives in a few fragments remained into the score of RV 819.
