Liber Inducens in Evangelium Aeternum

Liber Inducens in Evangelium Aeternum  was a book by Joachim of Fiore. The Library of St John the Beheaded held a copy which Edward Travers consulted in his research of the Great Intelligence. His daughter Anne would later find the book from her father's list.

When the Great Kingdom was formed, the Library was transformed into the Labyrinth of Thaumaturgy and Melanie Bush became the Technomancer. (PROSE: Millennial Rites) In the Labyrinth she learned of this book, considered to be one of the most malevolent books in the galaxy.

Mel later discovered that had a copy in his TARDIS library. (PROSE: The Quantum Archangel)

Behind the scenes

 * Joachim of Fiore was a real 12th century abbot but this work was invented by W. B. Yeats for his short story, "The Tables of the Law". Historically, wrote a work called the Introductorium in Evangelium Aeternum. Like Yeats' fictional book, this work was ordered destroyed by Pope Alexander IV. James Joyce suggests the Liber Inducens is real in his , noting that Yeats' story mentions the preface Joachim "is said to have prefixed to his Eternal Gospel."
 * Yeats' history of the book specifies that only a single copy survived after the destruction of the original. When the story was first published in an issue of The Savoy, the story ends with the sole copy's destruction. In the revised version its fate remains unclear.
