Ermengarda invincibile : drama per musica
Ermengarda invincibile is a 1675 Italian opera libretto (drama per musica) by Mauro Oddi, printed in Parma by Pietro del Frate and Galeazzo Rosati for performance audiences. The first picture is an engraved stage-scene frontispiece of a kneeling warrior, a standing woman in classical dress beside a column, and a cherub with a garland under billowing clouds, while the second is a title page framed by scrolled cartouche ornament around a heart pierced by arrows within a wheel. A designer could take the scrolled cartouche, the arrow-pierced heart emblem, and the crisp hatched engraving of drapery and armour as models for baroque emblem and frontispiece work.
