Giaches de Wert
In 1565 he went to work for the Gonzaga in Mantua and became choir master at the ducal chapel of S. Barbara where he stayed until 1592.  A lot of people were jealous of his good job, especially a man called Bonvicino who made life difficult for him.  It was then found that Bonvicino was having a love affair with de Wert’s wife, so she had to go back to live in Novellara.
