Estius, Gulielmus (William Hessels van Est), an eminent Roman Catholic theologian, was born at Gorcum, Holland, 1542, and studied at Utrecht and Louvain. He was for ten years professor at Louvain; in 1580 he became professor of divinity at Douai, and in 1603 chancellor of the University. Estius obtained great repute for learning and piety. Benedict XIV named him doctor
fundatissimus. He died at Douai September 20, 1613. His principal writings are Commentarii in Epistolas Aposfolicas (Douai. 1614-16; Colossians 1631, 3 volumes, fol. 3:1; Paris, 1679, fol.; Rouen, 1709, 2 volumes, fol.): — In quat. libros sententiarnsm commentarii (Par. 1638, fol.; Naples, 1720): — Annot. In preacipua difficiliora S.S. (Antw. 1621, fol.). His Commentary on the Epistles is extolled alike by Romanists and Protestants. There is a new edition, edited by Sausen (Ma ence, 1841, 8vo). — Horne, Introd. Bib. Appendix, page 134; Hoefer, Nouv. Biog. Ginerale, 24:588.
