Enoch Arden is a moving work by Tennyson - in fact, a veritable 'tear-jerker' - allegedly written while staying on Scilly (a commemorative plaque denoting this is to be found at the Tregarthen's Hotel on St. Mary's) in the early 1860's. It was first published in 1864.
It was part-set to piano accompaniment by Ricard Strauss in the late nineteenth century and became a popular parlour piece in the following years in Germany. The story of Enoch Arden (spoiler alert!) is described on the Minack Box Office link below, where you may purchase your tickets.
