ABSTRACT
The Tocci brothers were born in October 1877 at Locana, in the province of Turin, Italy. The illustration is from an advertisement when they were placed on display. They each had a well formed head, perfect arms and a perfect thorax to the sixth rib; they had a common abdomen, a single anus, two legs, two sacra, two vertebral columns, one penis but three buttocks. The right boy was christened Giovanni-Batista, and the left, Giacomo. Each individual had power over the corresponding leg on his side, but not over the other one. Walking was therefore impossible. All their sensations and emotions were distinctly individual and independent.
