the curriculum of studies for all Dominican students, introduced Aristotle to the classroom and probed the work of Neoplatonists, such as Plotinus. Indeed, it was the thirty years of work done by Aquinas and himself that allowed for the inclusion of Aristotelian study in the curriculum of Dominican schools. After suffering a collapse of health in 1278, he died on 15 November 1280 in the Dominican convent in Cologne, Germany. Since 15 November 1954 his relics are in a Roman sarcophagus in the crypt of the Dominican St. Andrew's Church in Cologne. Although his body was discovered to be incorrupt at the first exhumation three years after his death, at the exhumation in 1483 only a skeleton remained. Albert was beatified in 1622. He was canonized and proclaimed a Doctor of the Church on 16 December 1931 by Pope Pius XI and the patron saint of natural scientists in 1941. St. Albert's feast day is November 15. Writings Albert's writings collected in 1899 went to thirty-eight volumes. These displayed his prolific habits and encyclopedic knowledge of topics such as logic, theology, botany, geography, astronomy, astrology, mineralogy, alchemy, zoology, physiology, phrenology, justice, law, friendship, and love. He digested, interpreted, and systematized the whole of Aristotle's works, gleaned from the Latin translations and notes of the Arabian commentators, in accordance with Church doctrine. Most modern knowledge of Aristotle was preserved and presented by Albert. His principal theological works are a commentary in three volumes on the Books of the Sentences of Peter Lombard (Magister Sententiarum), and the Summa Theologiae in two volumes. The latter is in substance a more didactic repetition of the former. Albert's activity, however, was more philosophical than theological (see Scholasticism). The philosophical works, occupying the first six and the last of the 21 volumes, are generally divided according to the Aristotelian scheme of the sciences, and consist of interpretations and condensations of Aristotle's relative works, with supplementary discussions upon contemporary topics, and occasional divergences from the opinions of the master. Albert believed that Aristotle's approach to natural philosophy did not pose any obstacle to the development of a Christian philosophical view of the natural order. Albert's knowledge of natural science was considerable and for the age remarkably accurate. His industry in every department was great: not only did he produce commentaries and paraphrases of the entire Aristotelian corpus, including his scientific works, but Albert also added to and
