Last verified: 2026-09-03 ## Tombstone - **Artist:** James Cox - **Date:** c. 1773; Art UK dates the object 1772-1774. First recorded on public display in 1774, in James Cox's own descriptive catalogue of his Spring Gardens museum. - **Medium:** Chased and repousse silver over an iron and brass mechanical armature, with rotating glass rods simulating water, a music box, and gilt-brass and steel clockwork movements - **Dimensions:** Life-size, approximating the scale of an adult mute swan. No exact measurements are published in any of the sources consulted for this record; this is recorded as a gap, not filled with an estimate. - **Object type:** Clocks and instruments - **Period:** British, Georgian, third quarter of the eighteenth century - **Current location:** The Bowes Museum, Barnard Castle, County Durham, England - **Attribution:** disputed ## Summary A life-size silver swan, its mechanism substantially the work of the mechanician John Joseph Merlin, made and sold under the name of the London jeweller-showman James Cox around 1773. Wound, it performs a half-minute sequence that has drawn crowds for two hundred and fifty years: it turns and preens, appears to swim on a bed of rotating glass rods, notices a shoal of silver fish, and bends to catch and swallow one, all to a tune from a concealed music box. Mark Twain watched it do exactly this at the Paris Exposition Universelle of 1867 and wrote it into The Innocents Abroad; John and Josephine Bowes watched it at the same exhibition and bought it a few years later for their new museum in Barnard Castle, where it still performs daily.The record straightens out what a century and a half of retelling has blurred. The name on the object is not the name of the person who built its most admired feature, and that gap is not an oversight but a documented feature of how Cox's business worked. The date the Bowes acquired it is given as 1872, 1873 and 1882 across sources that ought to agree, including two pages published by the museum that now owns it; this record sets out the discrepancy and explains why the earliest date is the credible one. And the popular claim that the swan itself was built for the Chinese imperial court, though it echoes a genuinely documented episode in Cox's career, is not supported by any source found for this record and is treated here as unconfirmed rather than smoothed into fact.No formal export-style accession identifier appears on the museum's own public pages; the number given here, X.4653, is drawn from Art UK, the Bowes Museum's own partner cataloguing platform, and is treated as the object's working identification number pending a clearer citation from the museum itself. ## Provenance Every link carries a grade. `documented` means a cited source supports it, `disputed` means the identification is argued but not established, `unknown` means we have no owner for that span and have not bridged it. - **c. 1773-1774** James Cox's workshop and museum, Spring Gardens, London `[documented]` (manufacture and first public display) Made in Cox's workshop and first recorded in his own descriptive catalogue of the Spring Gardens museum, 1773-1774. Art UK dates the object 1772-1774. The mechanism is credited substantially, though not entirely, to John Joseph Merlin, who managed the museum from 1772 to 1775; other, unnamed craftsmen in Cox's employ are understood to have contributed the music box and water mechanism. - **1775-1867** Unrecorded `[unknown]` (gap) Cox's museum closed in 1775 following his Parliament-authorised lottery liquidation of 1773. What became of the swan specifically at that point, and where or with whom it remained for roughly ninety years, is not stated in any source consulted for this record. - **by 1867-1872 (or 1873)** Harry Emanuel, London jeweller `[documented]` (exhibition) Exhibited by Emanuel at the Exposition Universelle, Paris, 1867, priced at 50,000 francs according to the Bowes Museum's own account. Mark Twain saw it perform there and described it in The Innocents Abroad. John and Josephine Bowes also saw it perform at this exhibition. - **1872 (Bowes Museum's principal account; a second Bowes Museum page gives 1873)-present** John and Josephine Bowes, later the Bowes Museum `[disputed]` (purchase) Purchased from M. Briquet, a Parisian jeweller, for 5,000 francs (about 200 pounds), according to the Bowes Museum's own 'Silver Swan Story' page, which gives the year as 1872; a separate Bowes Museum-affiliated summary gives 1873. Art UK's own hosted record instead states the swan was bought by 'Founders, Josephine and John Bowes in 1882' -- a date this record treats as almost certainly an error, since Josephine Bowes died in February 1874, eight years before 1882, and could not have been a joint purchaser that year. This record adopts 1872 (with 1873 as a secondary possibility) as the credible date, both being consistent with Josephine's lifetime and with the couple's documented pattern of buying from the 1862, 1867 and 1871 exhibitions. The relationship, if any, between Briquet and Harry Emanuel (who had exhibited the swan in 1867) is not established by any source consulted. - **1885 (John Bowes's death)-1892** The Bowes Museum Trust, pending the museum's opening `[documented]` (posthumous transfer to the founded institution) Both founders died before the museum opened: Josephine in 1874, John in 1885. The purpose-built museum at Barnard Castle, designed by Jules Pellechet and John Edward Watson, opened to the public in 1892 with the swan among its collection. - **1892-present** The Bowes Museum, Barnard Castle `[documented]` (ongoing collection object) Held continuously by the museum since its opening. Working identification number X.4653 per Art UK's hosted catalogue record; not independently published on the Bowes Museum's own public website pages consulted for this record. On permanent display in the Picture Gallery, performing daily. Underwent documented conservation interventions in the 1940s (post-wartime), three times in the 1960s, in 2008, in 2012, and most recently a full restoration from September to December 2023 funded principally by a National Lottery Heritage Fund grant. ## Open questions - Did John Joseph Merlin build the entire mechanism, or only the head, neck and fish-catching sequence specifically? Sources agree on his credit for that sequence but do not agree on, or even address, who built the music box and the water mechanism. - Was the Silver Swan ever actually intended for the Qianlong court, or is the popular claim a conflation with Cox's separately and well-documented 1766 East India Company chariot gift? No primary source located for this record confirms or denies a China connection specific to the swan. - What happened to the swan between the closure of Cox's museum in 1775 and its documented reappearance, in the hands of the jeweller Harry Emanuel, at the Paris Exposition Universelle in 1867? Roughly ninety years are unaccounted for in every source consulted. - Did the Bowes acquire the swan in 1872 or in 1873? The Bowes Museum's own published materials give both dates without acknowledging the discrepancy. - Is the 1882 acquisition date given on Art UK's hosted record simply an error? Josephine Bowes died in February 1874, eight years before 1882, making her a purchaser in that year impossible as stated; no source consulted explains how the date entered the record. - What was the relationship between Harry Emanuel, who exhibited the swan in 1867, and M. Briquet, the Parisian jeweller named as the seller to the Bowes a few years later? No source consulted establishes whether Briquet was Emanuel's agent or a separate seller. - What are the swan's exact overall dimensions? No source consulted publishes a measurement beyond the description 'life-size'. - Is the widely repeated figure of approximately 2,000 moving parts, 139 glass rods and 113 neck rings independently verifiable, or does it trace back to a single unattributed source that later coverage has simply copied? ## Sources - [1] Art UK, 'The Silver Swan' (The Bowes Museum), object record, accessed via in-app browser rendering after a plain HTTP request returned 403.
