full_context: Document 1: Late Middle Ages: At the end of the Late Middle Ages, professional actors began to appear in England and Europe. Richard III and Henry VII both maintained small companies of professional actors. Their plays were performed in the Great Hall of a nobleman's residence, often with a raised platform at one end for the audience and a "screen" at the other for the actors. Also important were Mummers' plays, performed during the Christmas season, and court masques. These masques were especially popular during the reign of Henry VIII who had a House of Revels built and an Office of Revels established in 1545.

More recently, Martin Butler has argued for a date of 6 January 1621.

The British Library in London is the national library and is one of the world's largest research libraries, holding over 150 million items in all known languages and formats; including around 25 million books. The most senior art gallery is the National Gallery in Trafalgar Square, which houses a collection of over 2,300 paintings dating from the mid-13th century to 1900.
