  During the past decades Zabarella’s name has been linked to modern science. John Herman Randall published already in 1940 (and again in 1961) his famous idea on “the School of Padua” that would have been the precursor of modern science. Following Ernst Cassirer, Randall referred to the Renaissance discussions of regressus-method up to Zabarella as a preparation for Galileo Galilei’s new method of natural science. However, the Aristotelian terminology and doctrines that Zabarella and Galileo share, seem for the most part to have been commonplaces of late medieval and Renaissance thought. Galileo may have known Zabarella’s writings, but far more important source for Galileo was the Jesuit scholars, above all Paolo della Valle, working at the Collegio Romano at Rome (Wallace 1999, p. 338).
