Print entitled 'Patent Gymnasticon or, Machine for Exercising the Joints & Muscles of the human Body. Invented and Sold by F. Lowndes, Medical Electrician St. Pauls Church Yard' engraved by J. Walker and published by R. Phillips St. Pauls Church Yard. Published in the 'Monthly Magazine' in 1798. The accompanying text advised ‘The merchant, without withdrawing his attention from his accounts, and the student, while occupied in writing or reading, may have his lower limbs kept in constant motion by the slightest exertion, or, by the assistance of a child.’ This was exactly the kind of gentleman who might visit the St Paul’s Churchyard area of London where both Lowndes and his publisher Phillips were based, as this was the capital’s publishing centre in the 18th century.
