“ It is safe to say that no prehistoric monument in Great Britain has given rise to more speculation as to its origin, date and purpose; and although the few hoary stones still extant are but a small portion of the original structure they are still sufficiently imposing to excite the wonder of the passing traveller, and mysterious enough to puzzle the antiquary. Stonehenge was first mentioned by Nennius in the 9th century, who asserts that it was erected in commemoration of the 400 nobles who were treacherously slain near the spot by Hengist in 472. ”
