For many, the nature, design and organisation of such communities was set out in literary form in prospectuses such the anonymous Prospectus for the establishment of a Concordium or an industry harmony college published in 1841 and tracts such as John Thimbleby's Monadelphia
, 1830 or the anonymous Community of Icarie, 1847.
By the late summer of 1832, when the Moodies arrived in Cobourg, Charles Fothergill had left Port Hope and moved to present-day Pickering where, near the family of his second wife, he developed plans to establish a new community and model town he named Monadelphia
. Like so many of his visionary schemes including the "colony of gentlemen" at Rice Lake, this project faltered, in large part because a fire destroyed the mills in which he had heavily invested.
