De Rhetorica et Virtutibus (On Rhetoric and the Virtues)
A dialogue between Alcuin and Charlemagne on the art of speaking well and living rightly
Tradition: Carolingian educational literature; Ciceronian rhetorical tradition
Rhetoric and virtue in the Carolingian court — the art of persuasion as the servant of justice and Christian governance
De Rhetorica et Virtutibus is a dialogue in which Alcuin instructs Charlemagne in the principles of rhetoric and their relation to the moral virtues. The first part follows Cicero's De Inventione closely, summarising the five parts of rhetoric (inventio, dispositio, elocutio, memoria, pronuntiatio), the types of legal cases, and the methods of argument. The second part transitions from rhetoric to ethics, treating the four cardinal virtues (prudence, justice, fortitude, temperance) as the foundation of good governance. The work is characteristic of Alcuin's educational method: it transmits classical learning (here, Ciceronian rhetoric) within a Christian moral framework, making it accessible to a ruler who needed practical instruction in both public speaking and just rule. The De Rhetorica was widely copied and used in Carolingian schools as an introduction to both rhetoric and moral philosophy.

School Embodiments
The De Rhetorica transmitted Ciceronian rhetorical theory to the Carolingian schools, establishing rhetoric as a standard component of the trivium in medieval education.
"Rhetoric is the science of speaking well in civil questions." (De Rhetorica, opening definition, after Cicero)
The work is a systematic abbreviation of Cicero's De Inventione for a Carolingian audience — it preserves and transmits Roman rhetorical theory in an accessible form.
"We follow in the footsteps of Tullius [Cicero], the most eloquent of the Romans." (De Rhetorica, paraphrase)
The second half's treatment of the four cardinal virtues connects rhetorical art to moral character — the good speaker must be a good person.
"Prudence is the knowledge of what is good, what is evil, and what is neither. Justice is the disposition of mind which gives to each his due." (De Rhetorica, on the virtues)
The Christianisation of Ciceronian rhetoric — persuasion in the service of truth and justice, not mere power — follows Augustine's De Doctrina Christiana IV, which Alcuin knew well.
"The art of speaking is to be used in the service of truth, not for deception." (De Rhetorica, paraphrase)
The dialogue form (Alcuin instructing the Christian emperor) embodies the Carolingian alliance of learning and Catholic governance.
"The king must speak justly and govern wisely, guided by the four virtues." (De Rhetorica, concluding section, paraphrase)
Internal Tensions
The transition from rhetoric to ethics in the dialogue is somewhat abrupt — the connection between Ciceronian persuasion and the cardinal virtues is asserted rather than argued. The work is derivative (closely following Cicero) rather than original, which is both its purpose (transmission) and its limitation (no independent rhetorical theory).
I. Time
Both — divine eternity and created historical time. The dialogue's framework is the standard Carolingian-Augustinian one. Not primarily a cosmological text.
Attributes
II. Space
Finite, substantival, three-dimensional. Not independently theorised — the work concerns rhetoric and ethics, not cosmology.
Attributes
III. Matter
Created, finite, conserved. The embodied, speaking human being is the subject of rhetoric. Not independently theorised.
Attributes
IV. Observer
Embodied, active, rational. The rhetor/ruler must observe, judge, and persuade. Knowledge is mediate — acquired through study and practice. Personal metaphysical agency: the Christian God.
Attributes
V. Energy
Conventional patristic framework. Not independently theorised.
Attributes
VI. Information
The De Rhetorica is itself a vehicle for transmitting Ciceronian rhetorical knowledge to the Carolingian court. Rhetoric is the art of organising and communicating information persuasively.
