First edition of this highly entertaining and exceptionally influential early study of crowd behavior, a long-standing and classic guide to both popular psychology and the stock market, this copy splendidly extra-illustrated with 81 engraved plates, many vividly hand-colored, beautifully bound in full morocco-gilt by Bayntun.

Charles Mackay, a noted Scottish poet and journalist, attempted in this work to document and explain major "popular delusions" or seemingly irrational instances of mass action and belief. "Men," the author contends, "think in herds; it will be seen that they go mad in herds." In developing his theories of mass behavior, Mackay analyzes a breadth of historical examples ranging from witch hunts, alchemists, and famous haunted houses to the South Sea Bubble of 1720 and the Crusades. The impact of Mackay's work has been remarkably far-reaching, influencing such diverse fields as popular psychology and the charting of the stock market-as noted by The New York Times, which urged: "Any investor who has not read Charles Mackay's 'Tulipomania,' from his classic Extraordinary Popular Delusions, first published in 1841, should grab this book for that exercise alone." This set was originally issued with five engraved portraits—a frontispiece in each volume, and two additional portraits in Volume III. These are all present (four of the five have been finely hand-colored) for a total of 86 engraved illustrations. All volumes bound with half titles. Norman 1406. Kress C.5560.

Expert repairs to joints. Fine condition. A lovely extra-illustrated first edition, beautifully bound.
