Stanislaus, one of the chiefs of the Socinians in Poland, was born at Cracow in 1623. Becoming minister of a church at Lublin, he advocated the opinions of his sect so boldly that he provoked the enmity of the Jesuits, and was forced to flee to Hamburg. There, it is said, he was destroyed by poison in 1675. Lubienietski wrote Historia Reformacionis Polonicae, Freistadt, 1685. His chief work is his Theatrum Cometorum, Amsterdam, 1667; in which, after giving a minute account of all the comets previous to 1665, he endeavours to prove from their history, that if they portend anything whatever, they foretell both evil and good, and not evil alone, as the common opinion runs.
