The major buildings of the Late Middle Ages and the first centuries of the Early Modern Period were constructed in the predominant late medieval European style of Gothic architecture. Art-historical periodisations are Early English or "First Pointed" (late 12th–late 13th centuries), Decorated Gothic or "Second Pointed" (late 13th–late 14th centuries), and Perpendicular Gothic or "Third Pointed" (14th–17th centuries). The architect and art historian Thomas Rickman's "Attempt to Discriminate the Style of Architecture in England", first published in 1812, divided Gothic architecture in the British Isles into three stylistic periods. Rickman identified the period of architecture from William the Conqueror () to Henry II () as "Norman"; from Richard the Lionheart () to Edward I () as "Early English"; the reigns of Edward II () and Edward III () as "Decorated", and from Richard II () to Henry VIII () as "Perpendicular".
