The most favoured of these among the wealthy patrons of the day was the four-volume "Vitruvius Britannicus" by Colen Campbell. Campbell was both an architect and a publisher. It was essentially a book of design containing architectural prints of British buildings, which had been inspired by the great architects from Vitruvius to Palladio; at first mainly those of Inigo Jones, but the later works contained drawings and plans by Campbell and other 18th-century architects. These four books greatly contributed to Palladian architecture becoming established in 18th-century Britain. Their authors became the most fashionable and sought after architects of the era. Due to his book "Vitruvius Britannicus", Colen Campbell was chosen as the architect for banker Henry Hoare I's Stourhead house, a masterpiece that became the inspiration for dozens of similar houses across England.
