William Stukeley's 1740 study of Stonehenge stands out among the huge number of books on the subject. Stukeley was a pioneer preservationist. He lamented the callous treatment of the majestic ruins both by tourists and landholders. He coined the term 'trilithon' for the doorway-like arrangement of three stones, now common in the literature about megalithic architecture. Stukeley was one of the first to make accurate drawings of the site. The drawings are included in the text but also as seperate prints at the rear of the book to make research easisr The three dozen illustrations to this book, which show Stonehenge from every angle and document its context in the 18th century landscape, are still used today by scholars. He also did some rudimentary archeology, and describes opening the grave of a warrior princess.
