what it is
Perpendicular is the last phase of English Gothic, named for its window tracery: vertical stone bars (mullions) run straight up to the arch and are crossed by horizontal bars (transoms), dividing the glass into tall rectangular panels. The same grid of arch-topped panels covers walls, towers and screens. Arches are often four-centered, a flattened pointed shape. Ceilings are lierne vaults, with extra short ribs between the main ones, or fan vaults, in which ribs of equal curve spread from each support in a cone.
King's College Chapel in Cambridge (1446-1515) has the world's largest fan vault, built by John Wastell in 1512-1515. The Henry VII Chapel at Westminster Abbey in London (about 1503-1512) has a fan vault with hanging pendants. At Gloucester Cathedral, the Romanesque choir was refaced with Perpendicular paneling from 1331, and the Great East Window, finished about 1350, was then the largest window in existence. French Gothic of the same period, called Flamboyant, used curving, flame-shaped tracery instead of straight vertical lines.
how to spot one
history
The style appeared around 1330. Early examples include William de Ramsey's chapter house at Old St Paul's Cathedral in London (1332), destroyed in the fire of 1666, and the south transept (1329-1337) and choir of Gloucester Cathedral. Gloucester's cloisters, designed between 1351 and 1377 by Thomas de Cantebrugge, have the earliest surviving fan vaults in England. The name comes from Thomas Rickman, who classified English Gothic into periods in 1812.
Perpendicular was the main style for English churches from the reign of Richard II (1377-1399) to that of Henry VIII (1509-1547). It developed only in England, with no equivalent on the Continent or elsewhere in the British Isles. King's College Chapel and Bath Abbey were among the last large works before Henry VIII dissolved the monasteries between 1536 and 1541, and work on Bath Abbey stopped unfinished in 1539. In the 19th century, Charles Barry and A.W.N. Pugin used Perpendicular forms for the new Palace of Westminster in London (1840-1870).
