The Gothic Revival
The Gothic Revival was the deliberate copying of late medieval or Gothic art forms, especially those used in church architecture. It began as early as the 17th century in England. During the 18th century, Horace Walpole made a version of the style fashionable at Strawberry Hill, his Gothic home outside London. In the 1830s the designer AWN Pugin revived the Gothic style on more accurately medieval lines. He made it a moral issue, regarding it as the only style for a Christian country.
Motifs found repeatedly in the Gothic Revival include the three-leafed trefoil shape, the four-leafed quatrefoil, and the pointed arch, sometimes with applied crockets, or curled leaf-shapes, along the edges.
