What it is
Two companion treatises composed c. 1125–1130 by Hugh of Saint Victor, structuring the contemplative ascent through an elaborate diagrammatic image of Noah's Ark overlaid on salvation history. The De arca Noe morali addresses moral formation and affective preparation for contemplation; the De arca Noe mystica (Libellus de formatione arche) provides a visual-theological diagram intended to be drawn, taught, and meditated upon. Together they constituted a standard curriculum for advanced spiritual formation in 12th-century cathedral schools and monasteries across the German-speaking world, making them directly relevant to the Hohenstaufen court's religious formation networks.
Why it still matters
The spatial diagram of the Ark as a map of the soul's journey through history toward God remains a powerful framework for structured meditation; the moral treatise can be read section by section as a guide to spiritual examination.

Scivias (Know the Ways of the Lord)
Scivias Domini
Hildegard's first and most celebrated visionary work, composed c. 1141–1151, presents twenty-six visions on creation, redemption, and the Church in three books dictated to her scribe Volmar. Sections were read aloud to Pope Eugenius III at the Synod of Trier (November 1147 – February 1148) at the urging of Bernard of Clairvaux, receiving papal approval for publication. Frederick Barbarossa granted the Rupertsberg monastery an imperial charter of protection on 18 April 1163 (MGH, DDF.I 2/10:274-275), directly linking Scivias and Hildegard's wider prophetic ministry to the Hohenstaufen imperial orbit. The illuminated Rupertsberg Codex was almost certainly produced under Hildegard's direct supervision.
Liber Divinorum Operum (Book of Divine Works)
Liber divinorum operum
Hildegard's third and final major visionary work, composed c. 1163–1173/74, presents ten visions in three parts inspired by the Prologue of John's Gospel, exploring the relationship between the cosmos, the human person, and the divine Word. It was completed and first copied (the Ghent manuscript) in 1174, during the period when the Rupertsberg monastery continued to operate under the Hohenstaufen imperial protection charter granted by Frederick Barbarossa in 1163. An illuminated version was produced in the early 13th century for distribution. No single named Hohenstaufen court ownership record survives, but the text belongs to the same Rupertsberg corpus as Scivias.
Liber Vitae Meritorum (Book of the Rewards of Life)
Liber Vitae Meritorum
Hildegard's second major visionary work, composed 1158–1163, consists of six visionary sequences presenting thirty-five dialogues between vices and virtues — each vice given a seductive speech countered by its opposing virtue — with extensive treatment of purgatory, repentance, and restored union with God. It was composed at Rupertsberg during the peak of Hildegard's correspondence with Frederick Barbarossa and circulated within imperial German monastic networks. No single ownership record ties it to a named court member, but its composition period coincides exactly with Hohenstaufen patronage of Rupertsberg.
