(d. 1729)
The best known design by Campbell is Mereworth in Kent, built on a model from Palladio's Villa Rotonda near Vincenza. The plan of both villas embodies the Vitruvian ideal of perfect geometrical relationship, a circle within a square: a circular Roman temple behind four matching colonaded temple porticos. Campbell published Vitruvius Brittanicus (1715), sponsored by Boyle, along with two more volumes published in 1717 and 1725. He also published important editions of Palladios Four Books.
Stourhead (1722)
Stourhead
At the beginning of the eighteenth century a revolutionary change began to take place in garden design: the regular geometrical gardens in the French style of Le Notre (Versailles) gave way to the irregular curving forms of what eventually became known as the English landscape garden. Stourhead was one of the earliest examples of this shift in garden aesthetics. See the Roman Pantheon in the background below on the "natural" landscape designed by Henry "Burlington Harry" Flitcroft.
