Some 19th-century commentators believed that Tarshish was Britain, including Alfred John Dunkin who claimed "Tarshish demonstrated to be Britain" (1844), George Smith (1850),[16] James Wallis and David King's The British Millennial Harbinger (1861), John Algernon Clarke (1862), and Jonathan Perkins Weethee of Ohio (1887).[17] This idea stems from the fact that Tarshish is recorded to have been a trader in tin, silver, gold and lead [18] which were all mined in Cornwall. This is still reputed to be the "Merchants of Tarshish" today by some Christian sects.
