"A successor to his book A Cabinet of Medical Curiosities, this new collection of essays by Jan Bondeson illustrates various anomalies of human development, the lives of the remarkable individuals concerned, and social reactions to their extraordinary bodies." "Bondeson examines historical cases of dwarfism, extreme corpulence, giantism, conjoined twins, dicephaly, and extreme hairiness; his broader theme, however, is the infinite range of human experience. The dicephalous Tocci brothers and Lazarus Colloredo (from whose belly grew his malformed conjoined twin), the Swedish giant, and the king of Poland's dwarf - Bondeson considers these individuals not as "freaks" but as human beings born with sometimes appalling congenital deformities. He makes full use of original French, German, Dutch, Polish, and Scandinavian sources and explores elements of ethnology, literature, and cultural history in his diagnoses."--Jacket.
