Dom Illtyd Trethowan, monk of Downside, died on October 30, 1993. One of his last publications was a recent review in New Blaclfriars, but his writings, and his efforts to make available works of theology and philosophy by others, go back a very long way. His first article appeared in The Downside Review in 1935 (he subsequently came to be Editor of The Downside Review).His first book, Certainty, Philosophical and Theological, appeared in 1948. Before then he translated Eugène Masure’s seminal study Sacrifice du Chef (1944), and, as early as 1940 (together with Frank Sheed) he translated Etienne Gilson’s La Philosophic de Saint Bonaventure. Between 1948 and the time of his death he published 110 articles, plus numerous book reviews. He also produced seven substantial books, an edition of the writings of Walter Hilton, and several translations of important authors not much known in the English-speaking world—most notably, Maurice Blondel, Louis Lavelle, and Louis Bouyer.
Dom Illtyd was not a monk who travelled to teach and spend lots of time outside his monastery. In 1969 he lectured for one semester in the U.S.A. (at Brown University in Rhode Island), but he was otherwise a fixture at Downside from the day that he joined the community there. Yet simply in terms of pages printed, his published works and translations clearly place him in the forefront of twentieth century British Catholics writing on religion and trying to make available the writings on religion of others.
