Second revised, and significantly expanded edition of this remarkably interesting treatise containing an encomium for the new Copernican and Galileian science as well as its discoveries.
The Circulus Pisanus first appeared in Udine in 1642-1643. Its author, Bérigard (or Berigardo), was born in Moulin (France) and moved to Tuscany in 1625, possibly summoned there by Christine de Lorraine. He taught in Pisa from 1627 to 1638 and then at the University of Padua from 1639 until the end of his life in 1663.
The Circulus Pisanus is based on the 'disputationes circulares' held at the University of Pisa, which played such an important role in his teaching there. The work is cast in the form of a dialogue between Charilaus, a follower of Aristotelian philosophy, and Aristaeus, who upholds pre-Socratic philosophy, especially the atomism of such Ionian philosophers as Anaximander, Empedocles and Anaxagoras. Because atomism, like the new astronomical discoveries, had been condemned, Bérigard was very cautious about how he recovered ancient doctrines and dealt with the new philosophy. Even though he officially remained safely within the limits of traditional thought, he was also clearly familiar with the particulate (probably Cartesian) and experimental (Galileian) forms of the new philosophy. He describes many experiments in his book, including those pertaining to vacuums and the fall of bodies.
Many contemporary scientists – including, among others, Kenelm Digby, William Harvey, Evangelista Torricelli, Vincenzo Viviani, and Giovanni Alfonso Borelli – are mentioned with admiration in the work. The Circulus Pisanus also includes an encomium of Galileo (fol. Aaaa4, with the shoulder note Galilaei encomium). Bérigard, who must have known Galileo personally, always praised Galileo, although he remained firmly convinced of the earth's immobility.
Though Bérigard seems reluctant to fully cross the borders of the old philosophy, the Circulus Pisanus is undeniably a tribute to the new experimental sciences: beside the aforementioned encomium on Galileo, the Copernican hypothesis is mentioned and somewhat 'accepted'; the experiments of Torricelli are used to deny the vacuum only on the basis that God is everywhere and therefore a void cannot exist; and his praise for the telescope and the commentary on De Luna became an exposition of Copernicus' and Galileo's doctrines.
