GLAREANO (ENRICO DE LORIS, Henricus Loritus Glareanus). - Philosopher, mathematician, theologian, musician, and poet, b. at Glarus (Switzerland) in 1488, d. at Fribourg on 28 March 1563. He studied at Cologne with G. Coclico; in 1517 he moved to Paris, where he taught philosophy at a college founded by himself, but after scarcely a year he went to Basle, and in 1529 he settled at Fribourg, where he taught history and philosophy. Most learned in every field, he was a friend of the most illustrious men of his time. Although not insensitive to Protestant innovations, he always remained a faithful Catholic.
Among his many works on philosophy, history, and literature, mention should be made of Esagoge in musicen (Basle 1516) and Dodekachordon (ibid. 1547). This work, later reprinted in three volumes under the definitive title De musicen definitione ac divisione (ibid. 1560), was greatly appreciated, so much so that G. L. Womegger published an extract from it under the title Musice epitome ex Glareani Dodekachordon (ibid. 1557). P. Böhm, in vol. XVI of the Gesellschaft für Musik (Leipzig 1889), published a complete translation of the Dodekachordon with modern musical examples. He studied and translated Boethius, printed later by Rota in 1770. As a testimony to his affection for his native land, he wrote a Latin poem entitled Helvetiae descriptio et in laudatissimum Helvetiorum foedus panegyricus (ibid. 1515).
