There was also a rumor about his alleged mistress, who was said to be Anna Giro. Anna Giro first sang in a Vivaldi opera in 1726. She was a great singer and an attractive woman who became part of the composer's world and an indispensable primadonna of his subsequent operas. She continued to perform successfully on stage after Vivaldi's death.
