The fantasyland of Oz continues to fascinate steadfast Oz fans. They sympathize with the tin woodsman in his need for a heart, the cowardly lion in his need for courage, and with Dorothy as she searches for a way to return home to Kansas. In The Origin of The Wonderful Wizard of Oz, author Michele Rubatino reveals the mystery behind the evidence regarding the source of the maps found in Tik-Tok of Oz. Rubatino discusses the origin of the maps that Baum claims he discovered, rather than penned from his own imagination. The Origin of The Wonderful Wizard of Oz provides evidence to show the maps found in the Oz books, forty of them in all, were derived from drawing blueprints taken from the text of a King James Version Bible dating from around 1611. This information found by Baum formed the foundation for the creation of this fantasy series. Rubatino's discovery will help Oz enthusiasts, theologians, and all interested in the works of Baum to decipher the many facets he included in his stories. It will help fans gain a better perspective on the mysteries still to be found in the Bible and the Oz series.
