Antonio Lotti (5 January 1667 – 5 January 1740) was an Italian Baroque composer.
Lotti was born in Venice, although his father Matteo was Kapellmeister at Hanover at the time. Oral tradition says that in 1682, Lotti began studying with Lodovico Fuga and Giovanni Legrenzi, both of whom were employed at St Mark's Basilica, Venice's principal church, although there is no documentary evidence. Lotti made his career at St Mark's, first as an alto singer (from 1689), then as assistant to the second organist, then as second organist (from 1692), then (from 1704) as first organist, and finally (from 1736) as maestro di cappella, a position he held until his death. In 1717 he was given leave to go to Dresden, where a number of his operas were produced, including Giove in Argo, Teofane and Li quattro elementi (all with librettos by Antonio Maria Lucchini). Other works written in Venice include Giustino; Trionfo dell'Innocenza; the first act of Tirsi, Achille Placato, Teuzzone, Ama più che non si crede, Il comando inteso e tradito, Sidonio, Isaccio tiranno, La forze de sangue, Il Tradimento traditore di sè stesso, L'Infedeltà punita, Poresenna, Irene Augusta, Polidoro, Foca superbo, Alessandro Severo, Il Vincitore Generossi.
Because of the paucity of solid scholarship until recent decades, older reference books cite a good deal of misinformation regarding Lotti’s biography. Cicogna’s 1834 Delle inscrizioni Veneziane and Caffi’s 1854 Storia della Musica relied on oral tradition more than a century old to name works that Lotti supposedly composed for the Ospedale degl’ Incurabili. Later studies built upon that assertion to name Lotti as one of the supposed maestri of the Incurabili. The 2001 New Grove Dictionary of Music and Musicians went a step further to try to extrapolate when Lotti’s period of employment at the Incurabili would supposedly have been, building on a house of cards. However, recent studies establish that there is no documentary evidence whatsoever of any such employment ever taking place. The most current and most comprehensive studies by Caroline Giron-Panel and Pier Gillio establish conclusively that Lotti was not formally employed by the Incurabili, and that there is no evidence of his having composed any music for that institution, even on informal terms.,
