Sartorio's second visit to Venice was for the Carnival of 1669–1670, during which his next opera, L'Ermengarda regina de' longobardi, was performed. The librettist, Pietro Dolfin, a friend of both Sartorio and Duke Johann Friedrich, administered the duke's theatre loges and corresponded regularly with him between 1669 and 1678. Sartorio’s next stay in Venice lasted an entire year, from January or February 1672 to Carnival 1672–1673.
