Mantua, creating, among others, the title role in
Vivaldi's ''

of Bologna as a composer of oratorio circa
1719 and was named its Principal

In 1729 he joined Handel in London for two seasons, making his début in Lotario and creating roles in Partenope and Poro. In his time in London, Fabri also performed in revivals of Giulio Cesare, Tolomeo, Rinaldo, Rodelinda, and Scipione'', in which Handel transposed for
