Honorius Augustodunensis (c. 1080 – c. 1140), commonly known asHonorius of Autun, was a 12th-century Christiantheologian.

Augustodunensis said that he isHonorius Augustodunensis ecclesiae presbyter et scholasticus. "Augustodunensis" was taken to meanAutun (Augustodunum), but that identification is now generally rejected. There is no solid reasoning for any other identification (such asAugst/Augustodunensem praesulem near Basle,Augsburg/Augusta Vindelicorum inSwabia, orAugustinensis, fromSt Augustine's Abbey atCanterbury), so his by-name has stuck. It is certain that he was amonk and that he traveled toEngland and was a student ofAnselm's for some time. Toward the end of his life, he was in theScots Monastery, Regensburg,Bavaria.

Among Honorius's works are:

• Elucidarium: a survey of Christian beliefs (written in England). It was translated frequently into vernacular.
• Sigillum sanctae Mariae: a set of lessons for how to celebrate theAssumption, together with a commentary onThe Song of Songs, which he sees as being principally aboutMary.
• Gemma animae: An allegorical view of the liturgy and its practices.
• A commentary onThe Song of Songs, (preserved in a manuscript from c. 1170).^[1]
• A long commentary on thePsalms.
• Speculum Ecclesiae, a collection of sermons.
• Clavis physicae, the first part (1-315) is a summary of the first four books ofJohannes Scotus ErigenaPeriphyseon (De divisione naturae), the second part (316-529) is a reproduction of the fifth book.
• De luminaribus ecclesiae: a bibliography of Christian authors, which ends with a list of twenty-one of his own works.

His most important work was theImago mundi, an encyclopedia of popularcosmology and geography combined with a chronicle of world history. It was translated into many differentvernacular languages and was popular throughout the medieval period. It contained, among other things, a scheme for the operation ofguardian angels.
