Opera Omnia Medica & Chirurgica

The Botallo duct and the Botallo foramen, two aspects of a fetal heart, owe their names to Leonardo Bottallo, an Italian physician who described these parts in a short passage in Opera Omnia. Botallo worked at the French royal court and was also an army physician. The engraved title page of the Opera Omnia represents
several of Botallo’s experiences, such as the scene of soldiers being treated on the battlefield and a depiction of a patient being bled. Botallo was a believer in the
benefits of bloodletting, but as an army doctor he advocated gentler treatment of wounds than was customary at the time, and disagreed with those who felt that gunshot wounds were poisonous.
