John Dowland (1563 – buried 20 February 1626) was an English Renaissance composer, lutenist, and singer. He is best known today for his melancholy songs such as "Come, heavy sleep" (the basis of Benjamin Britten's 1963 composition for guitar solo, Nocturnal after John Dowland), "Come again", "Flow my tears", "I saw my Lady weepe" and "In darkness let me dwell", but his instrumental music has undergone a major revival, and with the 20th century's early music revival, has been a continuing source of repertoire for lutenists and classical guitarists.
Very little is known of John Dowland's early life, but it is generally thought he was born in London. Irish historian W. H. Grattan Flood claimed that he was born in Dalkey, near Dublin, but no corroborating evidence has ever been found either for that statement or for Thomas Fuller's claim that he was born in Westminster. In 1580 Dowland went to Paris, where he was in service to Sir Henry Cobham, the ambassador to the French court, and his successor, Sir Edward Stafford. He became a Roman Catholic at this time. In 1584, Dowland moved back to England where he was married. In 1588 he was admitted Mus. Bac. from Christ Church, Oxford. In 1594 a vacancy for a lutenist came up at the English court, but Dowland's application was unsuccessful – he claimed his religion led to his not being offered a post at Elizabeth I's Protestant court. However, his conversion was not publicised, and being Catholic did not prevent some other important musicians (such as William Byrd) from having a court career in England.
