Giacomo and Giovanni Battista Tocci

Giacomo and Giovanni Battista Tocci were conjoined twins born in Locana, Italy between 1875 and 1877 in either July or October.

Their father Giovanni Tocci had a breakdown due to the appearance of his first-born sons and was put into a lunatic asylum until he recovered a month later.

They determined the twins would live long, against the prediction of the professors at the Turin Academy of Medicine.

The twins had two heads, two necks, two ribcages that came together at the sixth rib, four arms, and two legs; they had two hearts, two stomachs, two sets of lungs, two separate diaphragms, and a shared large and small intestine.

For the rest of the 1880s, they were exhibited in most of the major cities in Italy, Switzerland, Germany, Austria, Poland, and France almost every day.

They never learned to walk as they did not have muscular development in their legs due to almost all of their time being exhibited, as it made it easier for their parents to exploit them.

Then in their 20s, Giovanni and Giacomo became recluses, never leaving the high-walled villa; their experiences in the freak show made them wary of any sort of exhibition.
