Venice, approx. 1698 - †?, after 1739
He devoted himself to composition at a young age and soon became known as a gifted and sensitive opera composer. Apart from his Venetian origins, which are confirmed in many documents, almost all the information usually given about his life before his arrival in Bohemia is unconfirmed. These include reports of his birth in 1698 as the son of a tailor in the Rialto district of Venice, studies under Giovanni Porta, and performances of his operas in Chioggia, Ferrara, Venice, and Baden-Baden in 1721-24. The earliest known records of him date from 1720, when he sang in performances of Lucio Papirio and Astarto in Udine and La ninfa bizzarra in Rovigo. He may be the singer mentioned as Antonio Biondi in the libretti of the performances of ''Il pastor reggio'' in Chioggia in 1721 and ''L'Arminio'' in Mantua in 1722.

His first opera, which can almost certainly be identified as ''La Climene'' was performed for Carnival 1721 at the ''Teatro Boegen'' in Chioggia or, according to Riemann, in Naples. The success was enough to earn him an invitation to Ferrara, where in the spring of 1722, other operas of his ("Caio Mario" and "Mitridate," with a libretto by A. Zeno) were performed at the ''Teatro Bonacossi'', adding to his already existing reputation. Also known outside Italy, Bioni went to Breslau the following year to prepare his "Filindo" at the ''Stadttheater'' and to Baden-Baden in 1724 to perform a new opera for the court theater, "Orlando furioso." In May 1724, Bioni was engaged by Antonio Denzio in Venice as composer for the ''Peruzzi Troupe'', which was to perform in Prague However, before coming to Bohemia, the Peruzzi Troupe undertook to give opera performances in the summer of 1724 at ''Kuks'', the estate of Count Franz Anton von Sporck in northeastern Bohemia.
