Although Handel continued to write operas, the trend towards English-language productions became irresistible as the decade ended. After three performances of his last Italian opera Deidamia in January and February 1741, he abandoned the genre.In July 1741 Jennens sent him a new libretto for an oratorio; in a letter dated 10 July to his friend Edward Holdsworth, Jennens wrote: "I hope [Handel] will lay out his whole Genius & Skill upon it, that the Composition may excell all his former Compositions, as the Subject excells every other subject. The Subject is Messiah".
