On Virtues and Vices (De virtutibus et vitiis)
De virtutibus et vitiis
Memor sum petitionis tuae et promissionis meae.
Our renderingI am mindful of your request and of my promise.
What it is
Dedicated to Count Wido, Margrave of the March of Brittany (attested in that role in 799), and composed around 799–800 at Charlemagne's court, this liber manualis by Alcuin adapts monastic moral theology for a layman engaged in political and military life. Organised around the virtues (faith, hope, charity, and the cardinal virtues) and then the vices (drawing on Cassian's tradition, including acedia), it shows how a magnate with limited time for formal religious life can pursue salvation through deliberate daily moral choices. Over 140 manuscripts survive, distributed across Europe, testifying to its extraordinary reach throughout the courts, monasteries, and cathedral schools of the Carolingian world and beyond. It opens: 'Memor sum petitionis tuae et promissionis meae'—a reminder that the book is itself an act of friendship and promise-keeping.
Why it still matters
Its tripartite structure—virtues to cultivate, vices to resist, then a synthesis in charity—provides a complete framework for an examination of conscience that any Christian can work through daily or weekly; it is particularly well suited to laypeople in demanding secular roles.
Kept alongside
Utrecht Psalter
Psalterium Ultraiectense
The Utrecht Psalter is among the most celebrated Carolingian manuscripts, containing the 150 psalms with 166 dynamic pen-and-ink illustrations—one per psalm—alongside canticles, the Te Deum, the Athanasian Creed, and material for the Divine Office. Most scholars agree it was produced at the monastery of Hautvillers near Reims, c. 820–840, on the initiative of Archbishop Ebbo of Reims, a foster-brother of Emperor Louis the Pious; its free and lively illustrations are best understood as reflecting a monastic rather than a strictly courtly audience. The manuscript reached Canterbury by c. 1000, was copied three times there in progressively more formal styles, and passed through Robert Cotton's library before arriving at Utrecht University Library in 1716. A later scholarly debate (Hincmar vs. Ebbo) allows a possible date as late as c. 850.
Via Regia (The Royal Road)
Via regia
Written in 813 and dedicated to Louis the Pious while he ruled Aquitaine as Charlemagne's heir, the Via regia is widely regarded as the first true European mirror for princes. Smaragdus, abbot of Saint-Mihiel, organized thirty-four chapters around specific royal virtues—peace, justice, mercy, patience, humility—grounding each in dense Old and New Testament exegesis rather than classical political theory. The text was explicitly designed to reform Louis's inner spiritual life as the precondition for a reformed realm. Three complete manuscript witnesses survive alongside additional partial witnesses; the first modern critical edition was published in 2024 (Peeters/Dallas Medieval Texts and Translations 30).
The Jesus Prayer
Молитва Иисусова
The short invocation 'Lord Jesus Christ, Son of God, have mercy on me, a sinner' has been the central personal prayer of Orthodox hesychasm for fifteen centuries, transmitted through the Desert Fathers, the Sinai tradition, and the Athonite hesychasts to Russian monasticism and lay piety. It appears within the Molitvoslov prayer rule documented as belonging to the Romanov family, and Empress Alexandra explicitly commended the prayer to her children by name in her letters and spiritual counsel. Elder Nikolai Guryanov later testified that Tsar Nicholas II recited it daily, though this oral tradition postdates the Tsar by decades and cannot be treated as primary documentation. The prayer's centrality to the Romanov spiritual world is well established; the personal frequency of its use by individual family members is plausible but cannot be confirmed from contemporary primary sources.
