parks of London at the end of the eighteenth century." Those Muggletons whose lives we know about would have rejected preaching as pointless and spiritually dangerous. Were there other groups of Muggletonians who operated differently? At present, historians cannot answer, but the possibility is there. Firstly, other denominations of that era, such as Methodists and Baptists, existed in a profusion of forms as E. P. Thompson's own index shows. Secondly, contact between those Muggletonians about whom we do know was sporadic, at best. "For example, those in Derbyshire were ignorant of the existence of any persons entertaining the same faith in London until one of their number removed thither to seek employment and, after residing there a short time, heard of the London bretheren by mere accident." Thirdly, the name existed widely in the public domain without much knowledge of what it meant. Sir Walter Scott received eternal damnation for his ignorant remarks in Woodstock. Charles Dickens incorporates All-Muggleton into Pickwick Papers. A character called Mrs Snowdrop in Douglas William Jerrold's Nell Gwynne (1833) says, "Nothing now will serve her but to go upon the stage. Tisn't my fault. I'm sure I put the pious Mr Muggleton under her pillow every night." During the nineteenth century, this formerly non-proselytizing Protestant sect became increasingly vocal and published several books intended for general audiences. In 1846, for example, the Muggletonian Isaac Frost published Two Systems of Astronomy, a lavishly illustrated book outlining the anti-Newtonian cosmology of the Muggletonians. This activity arose from the activity of the Frost brothers (Joseph and Isaac) who, having made their fortune in the Derby Brass Foundry business, proceeded to spend significant sums on publicising their sect once the family moved to London. A great number of books were published but very few were actually sold. Notable Muggletonian writers include Laurence Clarkson (1615–1667) an itinerant preacher born in Preston, Lancashire; John Saddington (1634? – 1679) a London sugar merchant, originally from Arnesby, Leicestershire; Thomas Tomkinson (1631–1710) a Staffordshire yeoman farmer who moved to London in the 1680s; Arden Bonell (b.? – 1746) a London Barber-Surgeon; and Isaac Frost (1793–1858) and Joseph Frost (1791–1857), brothers who ran the family metallurgy business in Clerkenwell, London. Also deserving mention is Alexander Delamaine (died 1687), a wealthy London tobacco merchant who began The Great Book in 1682, which became the Muggletonian archive.
