Charles Mackay, Scottish poet, journalist, and editor was best known in his day for his verses, some of which were set to music. His book,
Memoirs of Extraordinary Popular Delusions, was first published in 1841 (London: Richard Bentley, New Burlington Street, Publisher in Ordinary to Her Majesty), with a promise of additional material “should these be favorably received.” Apparently the work was indeed favorably received, resulting in a substantially revised, two-volume second edition being published in 1852 (London, Office of the National Illustrated Library, 227 Strand). The book has been reprinted often since.We present the second edition (1852) here. The two-volume set did not number the chapters. Volume I covered the present Chapters 1-8; Volume II began with “The Crusades.”Minor editorial modifications are: removing periods after the roman numerals designating kings and modifying some short abbreviations such as 2d to 2nd. Occasional typos are corrected, and a few corrections are made for consistency. Periods after subtitles are dropped.Lauren Landsburg
