GIORGIO SICULO. - Sicilian Anabaptist heretic of the 16th century. Information concerning his life is extremely scanty. Around 1550 he was probably already in Ferrara, where he preached against the “Lutherans.” There, in the first days of April of the same year, he was arrested because of his heretical doctrines, and on 23 May he was executed.
Of the many books by G. S., the only one apparently surviving is Epistola di G. S. servo fidele di Jesu Christo alli cittadini di Riva di Trento contra il mendatio di Francesco Spiera et false dottrina de' protestanti (Bologna 1550). It displays a mixture of rationalistic and mystical motifs analogous to that of Servetus, corresponding on the one hand to the common motifs of the culture of the period, with its confidence in the capacities of the human mind, and on the other to the Waldensian “spiritual” religiosity.
The identification, made by some, of G. S. Renato Camillo (v.) must be rejected.
