(This is a review of the whole Baroque Cycle.)
The saga ranges over the years 1640-1714 (roughly), following three principal characters: Daniel Waterhouse, a British natural philosopher and non-conformist; Eliza, a woman kidnapped from a remote British isle and abducted into the seraglio, who is later rescued and who subsequently makes her way into the court of Versailles and the world of high finance; and Half-Cocked Jack Shaftoe, King of the Vagabonds, adventurer, galley slave, pirate, and sympathetic everyman who will out-connive everyone unless the Imp of the Perverse compels him toward actions uncommonly glorious. Along the way we meet Newton, Leibniz, Hooke, Wren, Boyle, Locke, Peter the Great, royals of Europe, harpoon-chucking Russians, insidious Jesuits, etc., etc. and are led on great many an escapade in which, as the phrase goes, hilarity ensues.
In some interview Stephenson defines science fiction as fiction that takes ideas seriously, and by that measure this is major league science fiction. There are no robots, cyborgs, or time travel, but we do encounter the beginnings of modern science (promiscuous with alchemy), the transmutation of rare earth metals into coins, credit, and finance, the operations of the British Mint and Royal Society, the various sultanates of Asia, the global slave trade, the manufacturing of watered steel, cryptography, the logistical difficulties of sailing and of naval warfare, the beginnings of steam engines, and the lived experience of London’s sewer problems, with lots of clanging swordplay along the way. None of these are merely glimpsed, but each is explored in such depth as to prompt the reader to wonder who the hell this Neal Stephenson person is and how many heads he might possess. For a guy who, as he says, gets paid to sit on his butt and make stuff up, the achievement of his series is jaw-dropping, and it is a ripping good yarn to boot, all 916 + 815 + 886 pages of it.
