Franciscus Junius (1545–1602) was a professor of theology at the Universities of Heidelberg and Leiden and was one of the paragons of early Reformed Protestantism. He studied law at the academy of Bourges under François Douaren and Hugo Donellus, and he studied theology in Geneva under John Calvin and Theodore Beza. Junius and Immanuel Tremellius’ Latin translation of the Bible had an enduring and international impact on Protestant exegesis, and Junius’ De theologia vera became a standard textbook in theological prolegomena among Reformed Protestants.
