Spiders recur in themes for works by J. R. R. Tolkien. Tolkien included giant spiders in his 1937 book "The Hobbit" where they roamed Mirkwood, attacking and sometimes capturing the main characters. The character of Ungoliant is featured as a spiderlike entity, and as a personification of Night from his earliest writings. In "The Lord of the Rings", the creature's final surviving daughter Shelob is encountered as Frodo and Sam move through the mountain pass of Cirith Ungol. Shelob was featured in the film adaption of the last book of the "Lord of the Rings" series. Although described as giant spiders, Tolkien gave them fictional attributes such as compound eyes, beaks and the spinning of black webs. He also resurrected the Old English words "cob" and "lob" for "spider".
