Also in 1641, the Barberini were embroiled in the Wars of Castro, and Marazzoli set the events of the battle fought by Taddeo Barberini and Luigi Mattei in October 1641 to music in "Le pretensioni del Tebro e del Po", probably composed late in 1641. Marazzoli's "L'Armida" was performed in a revised version in January 1642 at a celebratory fete. At Carnival in 1642, Marazzoli had another opera performed, "Gli amori di Giasone e d'Isifile"; following this, Marazzoli returned to Ferrara and directed another performance of "Le pretensioni" to celebrate Taddeo Barberini's return to the city in March 1642.
