The work compiles a vast array of historical portraits focusing on eccentricity, wealth, and delusion in British society. The author presents the lives of notable figures such as William Beckford, whose immense Jamaican fortune funded the chaotic and costly construction of Fonthill Abbey, and Beau Brummel, the regency dandy who set the standard for masculine fashion before descending into poverty and mental decay. Other subjects include Sir Lumley Skeffington, the amiable baronet and dramatist, and John Mytton, the wealthy squire whose wanton extravagance led to the dismemberment of an ancient estate and his eventual death in a debtor's prison. The narrative also examines various impostors, alchemists, and recluses, detailing their motivations and the mechanisms of their delusions.
Throughout the pages, the text illustrates how great wealth often served as a millstone around the necks of its possessors, tempting them into extravagant freaks and social isolation. The author avoids moralizing, preferring to present trustworthy materials and original accounts that reveal the genuine texture of these bizarre lives. The volume captures a vanished social landscape where personal idiosyncrasy could flourish without modern homogenization, leaving behind tales of humour, thrift, and tragic downfall.
