The 'Sonata per Oboe Solo' in C minor, Fanna XV n.2/Ryom 53 is apparently the only extant piece by Antonio Vivaldi (b. 1678 in Venice. 1741 in Vienna) for oboe and basso continuo alone. 

Antonio Vivaldi (1678–1741) was one of the most productive composers of the Baroque era. His vast output included substantial quantities of chamber and vocal music, some 46 operas and a remarkable 500 concertos.
