Passage: The baroque style had never truly been to the English taste. Four influential books were published in the first quarter of the 18th century which highlighted the simplicity and purity of classical architecture: Vitruvius Britannicus (Colen Campbell 1715), Palladio's Four Books of Architecture (1715), De Re Aedificatoria (1726) and The Designs of Inigo Jones... with Some Additional Designs (1727). The most popular was the four-volume Vitruvius Britannicus by Colen Campbell. The book contained architectural prints of famous British buildings that had been inspired by the great architects from Vitruvius to Palladio. At first the book mainly featured the work of Inigo Jones, but the later tomes contained drawings and plans by Campbell and other 18th-century architects. Palladian architecture became well established in 18th-century Britain. Question: Who wrote Vitruvius Britannicus?
Colen Campbell
