The Petershausen Sacramentary is an Ottonian illuminated manuscript of around 960–980, produced in the scriptorium of Reichenau Abbey and containing the sacramentary and liturgical calendar. It is now held in the Heidelberg University library.
The miniature on folio 40 originally opened the manuscript and has been the subject of much debate. It displays attributes of the Virgin Mary and Ecclesia (personifications of the church), but differs from usual representations of either. Her regalia does not follow Northern iconography, being closer to Roman depictions of the Maria Regina. Her necklace and earrings recall the prependoulia of Byzantine crowns, while her patterned tunic and mantle give the appearance of Byzantine silks.[1] Consistent with earlier depictions of Byzantine empresses, interpreted the image as an "Imperial Virgin" and suggested it may have been inspired by Theophanu, the Byzantine princess who married Otto II.[2]
