The first reference to the "star chamber" is in 1398, as the "Sterred chambre"; the more common form of the name appears in 1422 as "le Sterne-chamere". Both forms recur throughout the fifteenth century, with "Sterred Chambre" last attested as appearing in the Supremacy of the Crown Act 1534 (establishing the English monarch as head of the Church in England). The origin of the name has usually been explained as first recorded by John Stow, writing in his "Survey of London" (1598), who noted "this place is called the Star Chamber, at the first all the roofe thereof was decked with images of starres gilted". Gold stars on a blue background were a common medieval decoration for ceilings in richly decorated rooms: the Star Chamber ceiling itself is still to be seen at Leasowe Castle, Wirral, and similar examples are in the Scrovegni Chapel in Padua and elsewhere.
