(Giovanni Valentino), Italian heretic, b. Consenza, Naples, about 1520. He fled to avoid persecution to Geneva, where in 1558 he was thrown into prison at the instigation of Calvin. Fear of sharing the fate of Servetus made him recant. He wandered to Poland, where he joined Alciati and Biandrata, but he was banished for his innovations. Upon the death of Calvin he returned to Switzerland, where he was arrested for heresy, 11 June, 1566. After a long trial he was condemned for attacking the Trinity, and beheaded at Berne, 26 (?) Sept. 1566. Ladvocat says “He died very impiously, saying he thought himself honored in being martyred for the glory of the Father, whereas the apostles and other martyrs only died for the glory of the Son.”
