Knowledge of Angels is a medieval philosophical novel by Jill Paton Walsh which was shortlisted for the 1994 Booker Prize. The book received mixed to positive reviews. Kirkus Reviews called it "an exquisitely mounted, immaculately designed fable." The Independent wrote "Contrived, often describing an idealised world but with luminous moments quite outside the normal run of contemporary fiction, this is a serious children's book for adult readers, and none the worse for that." Plot introduction Jill Paton Walsh writes At opposite ends of Grandinsula, a remote pre-reformation Christian island, shepherds find a creature with strange footprints stealing their lambs, and fishermen find a swimmer near exhaustion struggling towards the shore. The child cannot stand, eat or speak like a human being; the swimmer says he is a prince in the unheard of land of Aclar, and declares himself to be an atheist. Severo, Cardinal and Prince of the island, is confronted by a double conundrum. Could an atheist be in good faith? Not if the knowledge of God is inborn; then the atheist must once have known God, and reneged on the knowledge. If he is a renegade from the truth, he must be burned as a heretic; but Severo would dearly like to save him. How could it be found out whether everyone has inborn knowledge of God, since the teaching of the Church as best known to the greatest scholar on the island is unclear? Perhaps by teaching the wolf-child to speak, and then asking her... That will take time. Meanwhile, it is worth while trying to demonstrate the truth of God to the mysterious atheist in argument. What becomes of the argument, of the atheist, and of the wild child, and the effect of their fates on Severo, and the islanders who come in contact with either the Prince of Aclar, or the ferocious child Amara makes up the thread of the story. This is a fable about tolerance, and its conflict with moral certainty. Theme Although set in an idyllic setting – "an island somewhat like Mallorca, but not Mallorca" – Knowledge of Angels is essentially tragic in outcome. The stranger Palinor, a modern thinker from a distant and advanced society named Aclar, is cast ashore on the beach of a medieval culture where faith is all. Eventually he suffers torture and death for his rationalist beliefs in individual choice. The thoughtful Cardinal-prince who rules Grandinsula
