Anecdotes

Thomas Aquinas was so absorbed in his studies and reflections that he often forgot to eat. His fellow Dominicans regularly had to call him to the table for meals. This extreme focus on intellectual work became legendary at his convents in Naples and Paris.

During his studies at the University of Paris, Thomas Aquinas was so quiet and reserved that his classmates nicknamed him 'the dumb ox.' His teacher Albert the Great reportedly declared: 'This ox will bellow so loudly that his bellowing will fill the whole world' — a prophecy of the immense influence Aquinas would come to have.

Thomas Aquinas wrote the Summa Theologica, a monumental work of over 3,000 pages, in just a few years. He would dictate his thoughts to several secretaries simultaneously, working with remarkable productivity despite the challenging conditions of 13th-century life.

In 1274, while traveling to the Council of Lyon convened by the pope, Thomas Aquinas stopped at the monastery of Fossanova, where he died on March 7 at only 49 years old. His final words are said to have been about the Eucharist — the heart of his theological reflection.

Thomas Aquinas built his philosophical synthesis by drawing heavily on Aristotle, whose works had only recently been rediscovered in the West during the 13th century. This groundbreaking approach drew criticism from some Church circles, who viewed Aristotle as a pagan author incompatible with the Christian faith.
