San Luigi dei Francesi
From 1629 to 1632 Rossi was organist in the church of San Luigi dei Francesi. Rossi's first known opera dates from his second period of Roman service, while in the retinue of the wealthy Taddeo Barberini. His opera "Erminia sul Giordano" was premiered during the Carnival of 1633 at the theatre of the Palazzo Barberini (Rossi himself played the violin on stage as the sun-god Apollo), and appeared in print four years later. &lt;br&gt;
