Der Frustrated Harpsichordist: About Pur ti Miro, duet from the Monteverdi's Opera L'Incoronazione di Poppea.

(...) When he identified the music of still another younger composer, Francesco Sacrati, in Incoronazione, Alan Curtis concluded that the 1643 Venetian production of Incoronazione, like La Finda savia, an opera performed during the same season, at the same theater, presumably by the same troupe, must have been a collaborative effort, a pasticcio.

(...)It is ironic, too, that the youthfulness so prized in Incoronazione, especially in its final duetm could turn out to have been just that: but not Monveterdi's. "Pur ti miro" (and possibly more than that) may well be the work of a composer who was really young at the time it was composed, as were Sacrati, Ferrari and Laurenzi.

The source exhibits a debate among authors about the authorship of the work, in which exist more evidence that it's not Monteverdi. 

Additionally ♥, in the repertoire of Benedetto Ferrari there is Queste Pungente Spine (which draws the image of Christ tortured) on the same descending ostinato most passacaglia with a similar treatment, also present in the cantata (this) La Luciata Francesco Manelli, both composers were responsible for bringing opera to the first public opera theater (San Cassian in Venice). Here are the links.

♫ Queste Pungente Spine.

The bass used is contrastant to the lament one (as well descending but in minor, as the Lament of the Nymph of Monteverdi), the passacaglia in mayor key symbolizes both love and pain.

Sobre Pur ti Miro, dueto de la opera de Monteverdi L'incoronazione di Poppea

"(...) Cuando se identificó en incoronazione la música de otro compositor joven, Francesco Sacrati, Alan Curtis concluyó que la producción Vececiana de esta, como La Finta Savia (una opera presentada durante la misma temporada, en el mismo teatro, presumiblemente de la misma compañia) debió ser un esfuerzo colaborativo, un pasticcio. (...) Es irónico tambien que la muy apreciada juventud en Icoronazione, especialmente en el dueto final, pudo haber sido sólo eso: más no de Monteverdi. Pur ti Miro (y posiblemente más que eso) pudo ser el trabajo de un compositor que era realmente joven en el tiempo en que fue compuesto, así como Sacrati, Ferrari y Laurenzi."

La fuente expone un debate entre autores sobre la autoría de la obra, con evidencias que ponen en duda que haya sido Monteverdi.

Adicionalmente, dentro del repertorio de Benedetto Ferrari se encuentra Queste Pungente Spine (que dibuja la imagen de Cristo torturado), sobre el mismo ostinato descendente de passacaglia mayor, presente también en la cantata La Luciata de Francesco Manelli, ambos responsables de llevar la opera al primer teatro público de opera (San Casiano en Venecia).
