"EDITIO PRIMA SERVETI." The first edition edited by Michael Servetus [1511-1553]. Servetus was already under suspicion of heresy and here uses the pseudonym he adopted for his anti-trinitarian works: "Michel de Villeneuve." Servetus was an accomplished anatomist as well as geographer; his description of the pulmonary circulation of blood was much earlier than Harvey's but unfortunately was not widely recognized, as Servetus's secular works were destroyed alongside his theological ones after he was condemned for heresy. One ostensibly heretical element to the Servetus edition of Ptolemy is that Palestine is described as "not such a fertile land as was generally believed, since modern travelers reported it barren." This statement, however, is not even original to Servetus, but carried over from Johannes Regiomontanus's notes on the 1525 edition of the Pirckheimer translation.
