This edited collection explores how knowledge was preserved and reinvented in the Middle Ages. Rather than focusing on a historical period or specific cultural and historical events, it eschews traditional categories of periodisation and discipline, establishing connections and cross-sections between different departments of knowledge. The essays cover the period from the eighth to the fifteenth centuries, examining the history of science (computus, prognostication), the history of art, literature, theology (homilies, prayers, hagiography, contemplative texts), music, historiography and geography. Aspects of knowledge is aimed at an academic readership, including advanced undergraduate and postgraduate students, as well as specialists in medieval literature, history of science, history of knowledge, geography, theology, music, philosophy, intellectual history, history of language and material culture.
