Buonarroti's career as a courtier took a turn for the worse when the Grand Duchess Christina of Lorraine took offense at salacious language in "Fiera" (1619). In 1623 he dedicated the publication of verse by the Elder Michelangelo to his friend Maffeo Barberini, newly installed as Pope Urban VIII, and sought patronage from other members of the Barberini family. The last of his theatre pieces was "La Siringa", performed at the Palazzo Vecchio in 1634. In 1640 he lost his fortune in a bank failure at a time when the Wars of Castro (in which Rome and Florence took opposite sides) complicated relations with the Barberinis. His final years were spent writing the "Satires". He is buried in Santa Croce.
