Marsilius of Padua

Marsilius of Padua (Italian: Marsilio da Padova; born Marsilio Mainardi, Marsilio de i Mainardini or Marsilio Mainardini; c. 1275 – c. 1342) was an Italian scholar, trained in medicine, who practised a variety of professions. He was also an important 14th-century political figure. His political treatise Defensor pacis (The Defender of Peace), an attempt to refute papal claims to a "plenitude of power" in affairs of both church and state, is seen by some scholars as the most revolutionary political treatise written in the later Middle Ages. It is one of the first examples of a trenchant critique of ultramontanism in Western Europe. Marsilius is sometimes seen as a forerunner of the Protestant reformation, because many of his beliefs were later adopted by John Calvin and Martin Luther.
