The great iron clocks of the 13th century were the most sophisticated pieces of machinery that had ever been made. From those first horological dinosaurs, 'accurate' to within a few hours a day, to the latest mechanical movements, whose accuracy can be counted in fractions of a second, was a long uphill road. A few sudden advances were contributed by a handful of geniuses from France, Germany, Italy, America, Japan & Britain. Bibliography: p. [254]. Stock#43391. Vg / dj good+, some wear.
