Hortus deliciarum (Latin for Garden of Delights) is a medieval manuscript compiled by Herrad of Landsberg at the Hohenburg Abbey in Alsace, better known today as Mont Sainte-Odile. It was an illuminated encyclopedia, begun in 1167 as a pedagogical tool for young novices at the convent. It is the first encyclopedia that was evidently written by a woman. It was finished in 1185, and was one of the most celebrated illuminated manuscripts of the period. The majority of the work is in Latin, with glosses in German.
