Comus (A Mask Presented at Ludlow Castle, 1634) is a masque in honour of chastity, written by John Milton. It was first presented on Michaelmas, 1634, before John Egerton, 1st Earl of Bridgewater at Ludlow Castle in celebration of the Earl's new post as Lord President of Wales.
Known colloquially as Comus, the masque's actual full title is A Mask presented at Ludlow Castle, 1634: on Michelmas night, before the Rt Hon. Iohn Earl of Bridgewater, Viscount Brackly, Lord President of Wales, and one of His Maiesties most honorable privie councill. Comus was printed anonymously in 1637, in a quarto issued by bookseller Humphrey Robinson; Milton included the work in his Poems of 1645 and 1673. Milton's text was later used for a highly successful masque by the musician Thomas Arne in 1738, which then ran for more than seventy years in London.
