Elisabeth Le Guin's recent review of an edition of Joseph Bonno's L’isola disabitata (Eighteenth-Century Music 12/2, 247–249) provides a welcome opportunity to draw attention to two widely held misconceptions about the composer she describes as ‘The Neapolitan Giuseppe Bonno’. First, though certainly a member of the Neapolitan school by virtue of his ten years’ training in Naples under both Durante and Leo, Bonno was not himself Neapolitan. He was in fact born in Vienna on 30 January 1711, son of the imperial and royal footman Lucrezio Bonno (born Pralboino 1683, died Vienna 7 April 1742) and his first wife Maria Magdalena, née Kauner (born Riegersdorf (now Rückersdorf) 1679, died Vienna 6 March 1715). Secondly, while the title pages of printed sources use the Italian ‘Giuseppe’, Bonno himself always signed his name as ‘Joseph’; he was christened Joseph Johann Baptist Bonno after his godfather, the Emperor Joseph I.
