I found this novel to be highly creative and entertaining. I enjoy novels that stimulate ideas, challenge me with unique use of the English language, are not based just upon characterization and plot, and offer me something unique. This novel delivers on all four of these characteristic.This is a novel of ideas and reflection, a novel of an alternate universe than our own and yet this universe is populated with humans engaged in the same fragile and often dark mysterious existence as our own universe. Banville is crafty at conveying to the reader every 60 pages or so that this is an alternate universe, one where Mary Queen of Scots becomes Queen of England and beheads the traitor Elizabeth. There are many other hints including reference to the peace-loving diplomatic Caesar Borgia that populates this different world from our own. The games and complexity continues as the famous mathematician and philosopher of science Adam lies dying while being surrounded by his family and associates. Yet, he is famous for his mathematical proofs of alternate and infinite realities, one of which must be this book. He also is instrumental in developing salt water into an energy source and thus solving the issues of oil product shortages and pollution of the atmosphere. To further complicate the picture, this alternate reality is populated with the Greek gods interfering in human lives. These gods produce demi-gods such as Pan who in a Jungian twist is the unbridled Freudian Id of the dying genius Adam.Banville's use of the English language is superb, sending me to the dictionary and amazing me with his unique word combinations that so powerfully evoke the sensual world. He brings the reader to their sense with his continued themes of sight, taste, touch, smell, and hearing woven into the story.The characters in the novel are fun and drawn just well enough to carry the themes Banville wishes them to carry and to become more than vehicles. His characters are frail, vulnerable, sensitive, confused, conflicted, and challenged. They are not heroic though in this novel he makes the point that faulty humans can on occasion create brilliance. All the action takes place in one long day, so there is no plot in the narrative sense but with his flashbacks and narration through the eyes of the god Hermes, much of the past and future of these characters is revealed by this single day.A novel of ideas can be frustrating but I found this one to be a beautiful dream.
