This book, written by a very prolific writer, concerns one of the world's most fascinating examples of Sacred Art, the Ghent Altar-piece, which dates from the early 15th century.
This reviewer would not question Noah Charney's qualifications as an art historian, but the subject of this particular masterpiece, which is replete with heavy symbolism, displays his poor knowledge of Christianity. He refers to Blessed Fra Angelico, a Dominican friar ("Fra"), as a monk (page 7). He anachronistically refers to an ancient translation of the Blessed Virgin Mary's words at the Annunciation as "politically correct," and displays his arrogance and disrespect toward theology which he does not understand: "Even back then, virgin pregnancy sounded a bit suspect" (page 11). He accepts (without discussion) that the figure wearing the Triple Tiara is God the Father, but this is disputed, many believing the figure to be Christ the King.
On page 47, the author confuses Limbo with Purgatory, and makes hash of the Catholic tradition of praying for the dead. On page 72, he does not even make an attempt to understand the granting of Indulgences.
In discussing (if that be the mot juste of such careless writing) the Allied bombing of Monte Cassino (page 219), he blindly accepts the victors' version of history, where one makes violence upon suspicion, as later with our suspected "Weapons of Mass Destruction."
Moving from religious topics, we have a real howler on page 278, when he writes that the great Lincoln Kirstein "went on to direct the Metropolitan Opera." Indeed, it was probably a mistake to quote Kirstein's writings, since we can see the chasm of quality between Kirstein and Charney, whose efforts read like that of a schoolboy in comparison.
The entire book appears to be the result of a lack of research and comprehension, resulting in a completely superficial and disorganized study of the retable. One suspects that this author needs to read more and write less. In truth, the current Wikipedia article on the Altar-piece is far more mature, reliable, and interesting than this book.
