(b Macerata, c 1705; d ?Rome, 1779 or later). Italian alto castrato. After appearances in Rome (Porpora's Germanico, 1725) and Venice (1727 and 1729), he was engaged in 1729 for the Saxon court at Dresden at a salary of 792 thaler. He sang there in Johann Adolf Hasse's Cleofide (1731) and Cajo Fabricio (1734), but was given frequent leave to take outside engagements: at Rome in 1730, 1732 and 1739, at Vienna in 1731, when his performance in Antonio Caldara's Demetrio won the approval of Pietro Metastasio, and from October 1736 to June 1737 as a member of G. F. Handel's company in London. He made his London stage début at Covent Garden in a revival of Poro on 8 December, when he introduced two arias by Giovanni Alberto Ristori and one by Leonardo Vinci (one of only two occasions on which Handel is known to have allowed this practice in his own operas). Annibali was in the first performances of Handel's Arminio (title role, 1737), Giustino (title role, 1737) and Berenice (Demetrio, 1737), revivals of Partenope and Esther (in Italian), the pasticcio Didone, and probably the rewritten Il trionfo del tempo.
