Gesta Principum Polonorum (Deeds of the Princes of the Poles)
Gesta principum Polonorum
Boleslaus dux, Christi miles, non solum armis sed etiam orationibus pugnavit.
Our renderingDuke Bolesław, a soldier of Christ, fought not with arms alone but also with prayers.
What it is
Poland's oldest narrative chronicle, the Gesta Principum Polonorum was composed at the ducal court of Bolesław III Wrymouth by an anonymous Western monk working in the tradition of Einhard's Vita Caroli. It models Christian kingship through exemplary portraits of Piast rulers, praising martial courage inseparable from prayer, generosity to the church, and dynastic unity, while condemning fratricide and pride. The text functioned as living political theology: it was read at court, transmitted to later tutors, and shaped how the Piast dynasty understood its providential role in Latin Christendom. A critical edition with English translation by Paul Knoll and Frank Schaer was published by CEU Press in 2003.
Why it still matters
Though not a prayer text, the Gesta offers a concrete vocabulary for integrating Christian devotion with public vocation; the CEU Press translation makes it accessible for retreats, reading groups, or spiritual direction with those in leadership roles.

Codex Gertrudianus (Egbert Psalter with Gertrude's Prayers)
Psalterium Egberti cum Precibus Gertrudae
The Codex Gertrudianus is an illuminated tenth-century psalter originally made at Reichenau for Archbishop Egbert of Trier, brought to Kyiv by Gertrude of Poland — daughter of Mieszko II Lambert and Richeza of Lotharingia — upon her marriage to Iziaslav I around 1043–1050. Between 1078 and 1086 Gertrude added approximately ninety Latin prayers of her own composition in margins and on additional folios, accompanied by five Byzantine-style miniatures — depicting herself and her son Yaropolk before St Peter, the Nativity, the Crucifixion, and the enthroned Christ — executed by Kyivan craftsmen. Her prayers are intensely personal: she petitions for her exiled husband's restoration, for her son Yaropolk's protection and spiritual redemption, and for her own courage in sustained political crisis, making this one of the most intimate royal devotional documents from eleventh-century Europe. Gertrude is widely regarded by Polish scholars as the first Polish writer known by name; the codex is preserved in the Museo Archeologico Nazionale di Cividale del Friuli (Ms. CXXXVI).
Chronica Polonorum (Chronicle of the Poles) by Vincentius Kadłubek
Chronica Polonorum
Composed at the behest of Duke Kazimierz II the Just and completed before Wincenty's consecration as Bishop of Kraków in 1208, the Chronica Polonorum presents Polish history as a providential narrative in which just Piast rulers are rewarded and tyrannical ones punished by God. Written in dialogue form and saturated with classical and biblical allusion, it drew on Cicero, canon law, and Scripture to construct a theology of legitimate rulership. By the fourteenth and fifteenth centuries it was required reading for Polish educated clergy and nobility; Jan Długosz, royal tutor to the Jagiellonian princes, drew directly on it. Wincenty Kadłubek retired as a Cistercian monk at Jędrzejów and was beatified in 1764.
De consideratione (On Consideration)
De consideratione ad Eugenium papam
Five books of spiritual and pastoral counsel addressed personally to Pope Eugenius III, himself a Cistercian monk trained under Bernard, written between 1148 and 1152. It functions simultaneously as a mirror for the supreme ruler and as a manual of contemplative self-examination, warning against the tyranny of busyness and calling the highest officeholder back to inner recollection. A manuscript copy dated c. 1465 survives at the University of Chicago; the work was widely read by reform-minded clergy and rulers who circulated it as a model for Christian governance. Bernard addressed it directly to a head of state with whom he had a personal, documented formation relationship.
