an Italian theologian and founder of the school of Christian thought known as Socinianism and the main theologian of Polish Brethren (a Protestant Polish church). Sozzini's works, edited by his grandson Andrzej Wiszowaty and the learned printer Frans Kuyper, are contained in two closely printed folios (Amsterdam, 1668). They rank as the first two volumes of the Bibliotheca fratrum polonorum though the works of Johann Crell and Jonas Schlichting were the first of the series to be printed. They include all Sozzini's extant theological writings, except his essay on predestination (in which he denies that God foresees the actions of free agents) prefixed to Castellio's Dialogi IV (1575, reprinted 1613) and his revision of a school manual Instrumentum doctrinarum aristotelium (1586).
