Describing its new production of Francesco Cavalli’s 1668 opera Eliogabalo, the Gotham Chamber Opera compares the exploits of titular depraved Roman emperor Heliogabalus to Salome. There’s an obvious mistake here: Salome is an opera; Heliogabalus was a historical figure.

To accompany the exhibition “The Renaissance Portrait from Donatello to Bellini,” the early music ensemble TENET held court at the Metropolitan Museum of Art for a lovely concert of musical portraits from the late fourteenth and fifteenth centuries.
