Caesar's Messiah is a book written by American author Joseph Atwill and released in 2005 by Ulysses Press that examines religious and historical texts that have been used as a basis for mainstream Christian understanding of the historical Jesus. Atwill supports his comparison of the New Testament texts with Josephus' writings by pointing out shared chronological sequences between the events, and the use of shared symbolism. Caesar's Messiah is Atwill's first book.
