Christian Francken was a former Jesuit who became an anti-Trinitarian writer. In 1577 Francken left his position as professor of the Jesuit college in Vienna and commenced the publication from Basel and La Rochelle of many tracts against the order. François Du Jon in 1584 wrote his Defensio catholicae doctrinae de s. trinitate personarum in unitate essentiae Dei, adversus Samosatenicos errores against Francken. Francken's printer was arrested in Poland. On July 9, 1587 Franken was in Prague and introduced to John Dee. Later, on Oct.13 1592, Dee would show Franken's book of "blasphemie" to John Whitgift, the Archbishop of Canterbury, desiring it be confuted. Francken worked alongside Francis David, Johannes Sommer, Jacob Palaeologus as lector at the UnitarianGymnasium in Cluj in 1585 and between 1589-1591. He published two works in Prague in 1595. In 1598 Francken travels to Italy in the company of papal delegateCesare Speciano, where he was arrested and imprisoned by the Inquisition. The last document among the Inquisition's acts mentioning his name stems from 1611.
