The Westford Knight is a mysterious, controversial stone carving in Massachusetts. Some believe it is an effigy of a 14th century knight, evidence of an early European visit to the New World by Henry Sinclair, the Earl of Orkney and Lord of Roslin. In 1954, an archaeologist encountered the carving, long known to locals and ascribed a variety of origin stories, and proposed it to be a remnant of the Sinclair expedition. The story of the Westford Knight is a mix of history, archaeology, sociology, and Knights Templar lore. This work unravels the threads of the Knight's history, separating fact from fantasy.
