The work is arranged chronologically, with details about messiahs from before Christ through the dawn of the technological age at the end of the nineteenth century. It covers nearly 100 individual messiahs, including such Old Testament figures as King Hezekiah and Herod the Great, as well as later messiahs both obscure and historically renowned (even Queen Elizabeth I and King Charles I were touted as messiahs by certain devoted followers). Meticulously researched, the book includes an extensive bibliography.
