Medical advances often take steps back before they reach a breakthrough – and that's exactly what happened in 1667, when one man claimed that a medical experiment turned him into a sheep.
The story starts in the 1660s, when French and English scientists raced to perform the first successful blood transfusion into a human. But instead of taking blood from another person, these scientists used animal blood. In 1667, English scientists performed a sheep’s blood transfusion on Arthur Coga. Who was Arthur Coga? He started as a Cambridge-educated man, but by the end of his transfusions, he claimed to be Arthur Coga the Sheep Man, transformed into an animal after receiving too much sheep's blood.
Did something go terribly wrong in this 17th century blood transfusion? Did the sheep to human blood transfusion change something vital about Arthur Coga’s identity? The scientists at the Royal Society worried that they had done something crazy, or that they had gone too far in their drive to be first. They had certainly made progress, but in the process, they created a man who honestly believed he was an animal.
