This book is simultaneously a great example of what real scholarship looks like, and an epic exposure of how orthodoxy is often just agreed upon error.Agreed upon lies.Humphrey Carpenter long ago established in the "Tolkien Community" the idea that Tolkien was an isolated academic lost in the past, all his works, all his inspiration, springing from the past (the Oxford Don not reading contemporary literature).Later scholars, under the thrall of Carpenters authoritative voice, simply re-iterated Carpenter's disinformation.No one seemed to confirm Carpenter's judgement, they just assumed it to be correct and started from there.Well, it turns out it was not true.Not even close.Instead, author shows Tolkien was widely read in and influenced by, contemporary literature.Furthermore, Tolkien used insights (both positive and negative) gained from that literature (and his Catholicism) to inform and improve classic tales.A truly amazing book, wish I could give it six stars.
