  • In the heart of Damascus

    Kera PanniSeaside, California, United States Even as a child in the American suburbs, I knew my blood flowed from Syria. Relatives said my Jiddoo’s parents were farmers near Homs, and my Sittoo’s family was from the town of Mashta al-Helu in the coastal An-Nusayriyah Mountains. Still, I had only been able to create a fuzzy…

  • 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 Egyptian…

Unlike Michael Servetus (c. 1511–1553) he was not burned at the stake for heresy. Unlike Realdo Colombo (c. 1515–1559) he did not carry out thousands of dissections and work with Michelangelo, and unlike…

  • 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); was…

  • Michael Servetus (ca. 1511–1553)

    Michael Servetus is remembered for being burned at the stake for heresy and for making important observations on the pulmonary circulation. 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, one in…
