Horology Journal — John Pass 1809 Encyclopaedia Londinensis

Carry the precision of a golden age — when John Pass engraved the secrets of timekeeping for the Encyclopaedia Londinensis on 8 December 1809, turning mechanical genius into art: the front cover presents Horology Plate XI — Improved Clocks, documenting James Ferguson's 24-hour tidal clock and the Smeaton-Franklin single-hand clock in hand-coloured copperplate with amber washes for brass, steel blue for tempered steel, and warm grey for iron; while the back cover presents Horology Plate IV — Clock Work, revealing the hidden world of gears, weight systems, striking bells, escapements, and pendulums in cross-section and elevation — together forming a full-wrap panorama of Georgian horological knowledge at the decisive moment of transition to modern precision timekeeping.
