 Engelbert was one of the most learned men of his times, and there was scarcely any branch of knowledge to which his versatile pen did not contribute its share.His literary productions include works on moral and dogmatic theology, philosophy, history, political science, Holy Scripture, the natural sciences, pedagogy, and music.The best known of Engelbert's works is his historico-political treatise "De ortu, progressu et fine Romani imperii", which was written during the reign of Emperor Henry VII (1308–1313).
