In the summer semester of 2022, he was a professor of Medieval History at the University of Regensburg.

## Research

Sonntag focuses on medieval cultural studies. He has studied the comparative history of religious orders, including models, rituals and forms of symbolization as well as the cultural functions of games, of imitations, and of hair in medieval times.

### Symbols and Monasteries

In his book Klosterleben im Spiegel des Zeichenhaften (Monastic Life in the Mirror of the Symbolic), Sonntag applied the case-study of the traditional Benedictine communities and the Cistercians to investigate the following aspects of monastic life: monastic vows, hierarchical structures, meal communion, foot washing, care of the sick and the dying, guest services, and travel.

### Games in Medieval Times

In Religiosus ludens, Sonntag was one of the first scholars to study the roles of games in medieval monasteries.

### The Rule Commentary of Pontigny

Sonntag critically edited a little known commentary on the Rule of Saint Benedict, which originates from Pontigny. Nicole Bériou wrote the preface to the edition. This work is actually an extensive collection of sermons.

### The Williamite and Caulite Orders

Sonntag led the publication of the scientific editions of the statutes of the Williamite Order (1251–1349) and the legal texts of the Caulite Order (1220–1300, the latter with a preface by Phillip Adamo, the grand seigneur of Caulite research). Both scientific editions are provided with a translation.

### Hair in History

Sonntag has studied the cultural meaning of human hair in the Middle Ages. He applied a new approach that analyzes the interrelations between the social, political, ethical and religious functions of hair, and reveals the overarching structures of its usage.
