map of blood circulation    The Spaniard Miguel Servet discovered blood circulation and made a map of the blood system. The Calvinists paid him for this discovery by killing him. The chronicles say:
"On the 27th of October of 1553, Servet was taken to the hill of Champel. His body was bound to a stake with an iron chain and his neck was tied up with a thick rope. A sulphur-impregnated straw crown was put on his head and his book, “Christianismi Restitutio”, was placed at his feet. The suffering lasted for two hours because the wood being burnt was green. The Geneva reformers asked him to renounce his doctrine right up until the end. It was no use."
