Ibn al-Nafis and the pulmonary circulation

  Medical advances are often made over long periods of time, making it difficult to assign priority to any particular individual. Such has been the case for the ”discovery” of the pulmonary circulation, a distinction variously assigned to three anatomists of the sixteenth century, Michael Servetus, Realdo Colombo, and Andrea Cesalpino. But in 1924 the […]

Coronary moments: reflections on the impossible anastomosis

Andrea Cesalpino ca.1520–1603

  Of the three 16th century Italians anatomists who advanced our knowledge about the pulmonary circulation, Andrea Cesalpino is perhaps the least known. Unlike Michael Servetus (ca.1511-1553) he was not burned at the stake for heresy. Unlike Roaldo Colombo (1516- 1515 ) he did not carry out thousands of dissections and work with Michelangelo; and […]

Realdo Colombo (ca.1515-1559)

  Although Italy during the Renaissance consisted of a mosaic of independent states, its inhabitants and particularly academicians seem to have moved freely from one city state to another. Thus it came about that the anatomist Matteo Realdo Colombo was born and educated in the principality of Milan (in philosophy and later as an apothecary); […]

Michael Servetus (ca.1511-1553)

In his Christianismi Restitutio, a theological treatise that touched on medicine, he postulated that blood in the body was divided into different segments (which he called God- ordained spirits): one in the arteries, […]
