[Correspondence] Leonardo's mistake: not evidence-based medicine?

Renowned as one of the most influential figures in many different fields, Leonardo da Vinci (1452 –1519) was also a revolutionary anatomist. In his research on the human body and reproductive system, da Vinci devoted a series of drawings to conception and the fetus, in which the fetal membranes (chorion, amnion, and allantois) are represented for the first time.1 Additionally, when depicting c oitus, da Vinci introduced two errors: a canal in the penis connected to the spinal cord, and a canal linking the uterus to the breasts (figure).
