Venice-born Giacomo Leoni has published a four-volume translation of Palladio's Quattro libri dell'Architettura between 1716 and 1720, a huge success that is to see multiple editions in the following years and will be a primary vehicle for translating the essence of Palladio's manner among British designers through the patrons who employ them— for these expensive volumes are out of the reach of most builders, who can consult them only briefly in a gentleman's library.

This is followed by the ten-volume translation of Alberti's De Re Aedificatoria ("On Architecture"), the first modern book on the theories and practice of architecture.

Leoni illustrates the book with his own 'Designs for Buildings Both Public and Private'.

His book, which remains one of the truest translations of this important work, has been a valued architectural textbook to generations of aspiring architects.

Moor Park, a Palladian mansion set within several hundred acres of parkland in Hertfordshire, England, is called Moor Park Mansion because it is in the old park of the Manor of More.

The original house had been built in 1678–9 for James, Duke of Monmouth, and inherited by his duchess after he was beheaded.

Benjamin Hoskins Styles, who has made a fortune in the South Sea Company, purchases it and has it reconstructed around 1720 by Leoni, who refaces the house with Portland stone and adds its grand portico and Tuscan colonnades (since demolished), with a painted staircase by Sir James Thornhill.
