John Dowland (1563 – buried 20 February 1626) was an English Renaissance composer, singer, and lutenist. He is best known today for his melancholy songs such as "Come, heavy sleep" (the basis for Benjamin Britten's Nocturnal), "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 has been a source of repertoire for lutenists and classical guitarists during the twentieth century. Very little is known of 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 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 publicized, and being Catholic did not prevent some other important musicians (such as William Byrd) from having a court career in England.
