The spectacular site of Tivoli was familiar to all travellers on the Grand Tour through the Roman poets, especially Virgil and Horace. It was also a favourite sketching-ground for artists from the 17th century onwards, a tradition that deeply influenced Wilson. Hadrian's Villa was a complex of palaces, baths, temples, libraries, state rooms and service quarters, which included the greatest Roman example of the Alexandrine garden, recreating a sacred landscape. Built as a retreat for the Emperor Hadrian (76-138 AD) it fell into ruins over the ages. Recently the precise location has been identified by Jonathan Yarker as the West Belvedere of the Villa with a farmhouse above built by Sebastiano Soliardi.
