The most influential follower of Palladio anywhere, however, was the Englishman Inigo Jones, who travelled throughout Italy with the 'Collector' Earl of Arundel, annotating his copy of Palladio's treatise, in 1613–14. The "Palladianism" of Jones and his contemporaries and later followers was a style largely of facades, and the mathematical formulae dictating layout were not strictly applied. A handful of great country houses in England built between 1640 and 1680, such as Wilton House, are in this Palladian style. These follow the great success of Jones' Palladian designs for the Queen's House at Greenwich and the Banqueting House at Whitehall, the uncompleted royal palace in London of King Charles I.
