Giambattista Varesco

Father Giambattista Varesco (26 November 1735 – 25 August 1805) was a chaplain, musician, poet and (most famously) librettist to Wolfgang Amadeus Mozart. His given name variously appears as Giambattista, Gianbattista, Giovanni Battista and Girolamo Giovanni Battista. He is sometimes referred to with the Italian title ''Abate'' or the French ''Abbé'', both used for priests: he was chaplain at the Salzburg court chapel from 1766. Provided by Wikipedia
