Guy Claessens studied Classics at KU Leuven. In 2011 he obtained his PhD in Philosophy with a dissertation on the early modern reception of Proclus’ commentary on Euclid’s Elements and the Neoplatonic concept of geometrical imagination. His research is mainly concerned with Renaissance (Neo-)Platonism, and currently focuses on the reception of Proclus’ natural philosophy and on Renaissance commentaries on Plato’s Timaeus. He has widely published on Renaissance philosophy, from the Quattrocento and Cinquecento reception of the Timaeus and Phaedrus to the Platonisms of Filelfo and Kepler.
