Published in London by John Wilkes for the \u003cem\u003eEncyclopaedia Londinensis\u003c\/em\u003e and dated 8 December 1809, these copperplate engravings—hand-coloured with watercolour in luxury editions—were conceived as engineering diagrams for clockmakers, astronomers, and navigators of the age. At a time when horology was a frontier science essential to maritime navigation and astronomical precision, these plates documented the decisive transition from friction-based mechanisms to the refined, efficient systems that would define modern timekeeping.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFront Cover — Horology, Plate XI: Improved Clocks:\u003c\/strong\u003e Numbered diagrams 67 through 75 document the most celebrated clock innovations of the early 19th century. At the right, James Ferguson’s 24-hour clock—designed to indicate tidal movements—displays its elegant face and intricate mechanism. At the left, the single-handed clock attributed to the Smeaton-Franklin tradition offers a study in refined minimalism. Watercolour washes in amber, steel blue, and warm grey differentiate brass from steel, wheel from escapement, face from frame—transforming a technical diagram into a composition of quiet, geometric beauty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBack Cover — Horology, Plate IV: Clock Work:\u003c\/strong\u003e Numbered diagrams 56 through 62 reveal the hidden world of gears, weight systems, striking bells, escapements, and pendulums in cross-section and elevation. The colour application—functional rather than decorative—uses warm brass tones and cool steel greys to guide the eye through each component with the clarity of a master craftsman’s blueprint. Together with the front cover, the full-wrap design creates an uninterrupted panorama of horological knowledge, flowing from mechanism to instrument across the entire journal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy This Journal Inspires:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTwo landmark plates from the \u003cem\u003eEncyclopaedia Londinensis\u003c\/em\u003e (1809) united in a single full-wrap design—engraved by John Pass, one of Georgian London’s most accomplished scientific illustrators\u003c\/li\u003e\n\u003cli\u003eHand-coloured copperplate technique in amber, steel blue, and warm grey—functional beauty at its most enduring\u003c\/li\u003e\n\u003cli\u003eA tribute to the age when horology was the cutting edge of science, essential to maritime navigation and astronomical precision\u003c\/li\u003e\n\u003cli\u003eFerguson’s 24-hour tidal clock and the Smeaton-Franklin single-hand clock—two milestones of Georgian timekeeping on a single cover\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eProduct Details:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e Hardcover journal with matte laminated full-wrap cover\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePages:\u003c\/strong\u003e 150 lined pages (75 sheets) with perforations for easy removal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBinding:\u003c\/strong\u003e Casewrap sewn binding that lays flat and flexes for comfortable writing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 5.5 × 8.5 inches, lightweight and portable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.1 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCover:\u003c\/strong\u003e John Pass 1809 copperplate engravings from Encyclopaedia Londinensis, matte finish; small 0.5\"x0.5\" production barcode on back\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003ePerfect For:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHorology enthusiasts, clockmakers, and antique watch collectors celebrating the golden age of Georgian timekeeping\u003c\/li\u003e\n\u003cli\u003eHistorians and researchers of Georgian science, technology, and encyclopaedic illustration\u003c\/li\u003e\n\u003cli\u003eCollectors of rare copperplate engravings and the scientific publishing tradition of Regency London\u003c\/li\u003e\n\u003cli\u003eNavigators, astronomers, and lovers of precision instruments drawn to the intersection of engineering and fine art\u003c\/li\u003e\n\u003cli\u003eDesign lovers who appreciate the quiet geometric beauty of technical diagrams rendered with an artistic hand\u003c\/li\u003e\n\u003cli\u003eThoughtful gift seekers looking for a historically extraordinary journal for academics, curators, and curious minds\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eCarry the precision of a golden age—open this journal and write in the margins of time, where every second was once a hard-won triumph of human ingenuity.\u003c\/em\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eEU representative\u003c\/strong\u003e: HONSON VENTURES LIMITED, gpsr@honsonventures.com, 3, Gnaftis House flat 102, Limassol, Mesa Geitonia, 4003, CY\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProduct information\u003c\/strong\u003e: Generic brand, 2 year warranty in EU and Northern Ireland as per Directive 1999\/44\/EC\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCare instructions\u003c\/strong\u003e: Use a soft, clean and dry cloth to gently brush any dust or dirt off from the center of book outwards.\u003c\/p\u003e","brand":"LeBonJournal","offers":[{"title":"Journal","offer_id":63348810711409,"sku":"10877724330038147805","price":18.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/5367\/0769\/files\/Horology_journal_with_John_Pass_1809_improved_clocks_and_clock_work_copperplate_engravings_from_Encyclopaedia_Londinensis.jpg?v=1774636173","url":"https:\/\/lebonjournal.com\/products\/horology-journal-john-pass-1809","provider":"LeBonJournal","version":"1.0","type":"link"}
