La Rosmira fedele, also known in modern revivals as Partenope, is a 1725 opera by Leonardo Vinci. It is largely based on Domenico Sarro's 1707 setting of Silvio Stampiglia's libretto Partenope but with new arias by Vinci.[1] It was premiered 31 January with Antonia Merighi as Queen Partenope and Faustina Bordoni as Rosmira.[2]Vivaldi set Stampiglia's libretto as a pasticcio Rosmira Fedele in 1738 using arias by Handel, Hasse, Pergolesi, and minor local Venetian composers.[3]
^Kurt Sven Markstrom - The Operas of Leonardo Vinci, Napoletano 1576470946 2007 - Page 108 "This work demonstrates both the proximity of pasticcio and composition and the hegemony of the aria in eighteenth-century Italian opera, since it is Vinci's set of new arias that transforms Sarro's Partenope into Vinci's La Rosmira fedele.

^Gramophone Rosmira Fidele "few of its arias were actually composed by Vivaldi, who prepared this entertainment by extensively borrowing arias by Handel, Hasse, Pergolesi, and some obscure Venetian composers who will most likely remain forgotten."
