Works & Achievements
Ruling in the name of her son Otto III for eight years, Theophanu maintained the unity of the Empire, held in check the ambitions of rival princes, and preserved the alliance with the papacy. Her regency is considered among the most stable and best conducted of the western Middle Ages.
Through her presence at court, Theophanu introduced Byzantine arts, ceremonies, craftsmen, and manuscripts into Germanic territory, directly contributing to the flourishing of the "Ottonian renaissance." Her influence can be traced in the illuminated manuscripts, ivories, and goldsmithing of the late tenth century.
Theophanu made several journeys to Italy to consolidate imperial authority over Rome, renew alliances with Lombard lords, and maintain balanced relations with the papacy. She negotiated with a skill acknowledged by contemporary chroniclers.
The dozens of diplomas and charters issued in the name of Otto III during her regency constitute a major historical source for the history of the Empire. Some, signed in her own name with the masculine title of *imperator*, bear witness to her sovereign conception of government.
Anecdotes
The exact origin of Theophano remains an enigma for historians: presented as a Byzantine princess at her marriage to Otto II in 972, she was probably not the daughter of an emperor but the niece of Basileus John I Tzimiskes. This disappointed the Ottonian delegation, which had hoped for a porphyrogenneta — a princess “born in the purple” — but Otto I ultimately accepted the union for diplomatic reasons.
At the sudden death of Otto II in Rome in 983, Theophano had to defend the regency against Henry the Quarrelsome, Duke of Bavaria, who seized the young Otto III, then three years old. Through a skillful alliance with Archbishop Willigis of Mainz and her mother-in-law Adelaide of Italy, she recovered her son and established herself as regent, foiling the ambitions of the rebellious duke.
In an unprecedented act in the medieval West, Theophano signed certain imperial charters with the masculine title “Theophanu gratia divina imperator augustus,” claiming the full weight of sovereign power without any concession to her female status. This deliberate gesture, inherited from the Byzantine tradition in which women could rule in their own name, reflects her lofty conception of regental authority.
An ivory carved panel, now housed at the Musée de Cluny in Paris, depicts Otto II and Theophano crowned by Christ himself, side by side and of equal stature. This hybrid work blends Byzantine iconography with Ottonian art, and illustrates better than any other document the exceptional position of Theophano — a sovereign in her own right, not merely a self-effacing consort.
Theophano introduced many Byzantine customs unknown in the West to the Ottonian court: daily bathing, court ceremonies strictly codified according to Constantinople's protocol, Greek craftsmen and illuminators, and the use of purple ink reserved for emperors. These practices fascinated and scandalized certain Germanic chroniclers in equal measure, who viewed them as an Eastern influence they deemed suspect.
