Tito Manlio was performed for the fi rst time in Mantua as second work of the Carnival season of winter 1719. Vivaldi set the libretto of La fi da ninfa, a dramma per musica in three acts by Scipione Maffei, with a view to its use for the inauguration of the new theatre of the Accademia Filarmonica of Verona, which took place on 6 January 1732, during the Carnival season, elaborate stage sets being provided by Francesco Bibbiena. The critical edition is based on the collation of the two complete manuscripts of the work kept at the National University Library of Turin: the Vivaldi's autograph and a copy realized by fi ve copyists under the direct control of the composer. / Voix Et Piano
