Samson (HWV 57) is a three-act oratorio by George Frideric Handel, considered one of his finest dramatic works. It is usually performed as an oratorio in concert form, but on occasions has also been staged as an opera. The well-known arias "Let the bright Seraphim" (for soprano) and "Total eclipse" (for tenor) are often performed separately in concert.
The German-born Handel had been resident in London since 1712 and had there enjoyed great success as a composer of Italian operas. His opportunities to set English texts to music had been more limited; he had spent the years 1717 to 1719 as composer in residence to the wealthy Duke of Chandos where he had written church anthems and two stage works, Acis and Galatea and Esther; and had composed vocal music to English words for various royal occasions, including a set of Coronation anthems for George II in 1727, which had made a huge impact. In 1731, a performance of the 1718 version of Esther, a work in English based on a Biblical drama by Jean Racine, was given in London without Handel's participation and had proved popular, so Handel revised the work and planned to present it at the theatre where his Italian operas were being presented. However the Bishop of London would not permit a drama based on a Biblical story to be acted out on the stage, and therefore Handel presented Esther in concert form, thus giving birth to the English oratorio.
Esther in its revised form proved a popular work, and Handel, though still continuing to focus on composition of Italian operas, followed Esther with two more sacred dramas with English words to be presented in concert form, Deborah, and Athalia (which, like Esther, was also based on a Biblical drama by Racine), both in 1733. Such was the success of his oratorios in English that eventually Handel abandoned Italian opera, his last being Deidamia in 1741, and produced a string of masterpieces of oratorio in English.
