The concerto transcriptions of Johann Sebastian Bach date from his second period at the court in Weimar (1708–1717). Bach transcribed for organ and harpsichord a number of Italian and Italianate concertos, mainly by Antonio Vivaldi, but with others by Alessandro Marcello, Benedetto Marcello, Georg Philipp Telemann and the musically talented Prince Johann Ernst of Saxe-Weimar. It is thought that most of the transcriptions were probably made in 1713–1714. Their publication by C.F. Peters in the 1850s and by Breitkopf & Härtel in the 1890s played a decisive role in the Vivaldi revival of the twentieth century.
