A Plausible Historical and Forensic Account of the Death of Thomas Aquinas

Thomas Aquinas (1225-1274) was an influential medieval Christian theologian and arguably one of the greatest scholastic philosophers. He produced more than 60 works in his 48 years, including his magnum opus, the Summa Theologica. The Catholic Church regards him as a canonized saint and one of 37 Doctors of the Church. On his way to an ecumenical council in 1274, he was "struck with sudden illness" requiring rest at a monastery where he was cared for until death several weeks later. An obscure Latin text describes an incident where he hit his head violently on an overhanging branch. Becoming progressively ill, he arrived at a Cistercian abbey where he died on March 7. Through an analysis of his final illness as documented in key Latin and Italian historical texts, and careful observation of the reputed skull relic in Priverno, Italy, the authors postulate that Aquinas may have suffered a traumatic brain injury and that his death at age 48 was occasioned by a chronic subdural hematoma. Examination of the skull was inconclusive; however, the historical textual analysis supports this theory. A more in-depth forensic analysis of the skull may help confirm the diagnosis.
