The Stuttgart Psalter is a richly illuminated 9th-century psalter, considered one of the most significant of the Carolingian period. Written in Carolingian minuscule, it contains 316 images illustrating the Book of Psalms according to the Gallican Rite. It has been archived since the late 18th century at the Württembergische Landesbibliothek in Stuttgart.
Through paleographic analysis undertaken by Bernhard Bischoff in the 1960s it is now commonly accepted that the manuscript originated around 820 at the scriptorium at St. Germain-des-Prés in Paris, a royal monastery which enjoyed the personal patronage of Charlemagne.
The original owner or sponsor of the book is not known. The first mention of the manuscript's existence occurs in a letter dated in 1787 regarding its sale to Charles II Duke of Wurtemberg, and its presence in the ducal library at Stuttgart is recorded for the first time in 1818.
There are 162 decorated initials, including one at the beginning of each psalm, which show floral, geometrical, zoomorphic, and interlaced patterns and motifs. Two or three miniatures are included within each psalm text, which can be categorized in three ways.
The first, literal, illustrating the actual psalm text; then, historical, where the psalm text refers to other episodes in the Hebrew Bible and finally, Christological, where the text is seen as predictive or relevant to the life of Christ in the New Testament.
The Stuttgart Psalter is of great interest to Carolingian historians because of the detail and variety of the contemporary objects it portrays: plants and animals, architecture, battles and militaria, dress and fashion, gender roles, appearance of Frankish nobles, demonology, representation of imagined Jews, hunting and farming techniques, church ritual and priestly vestments, music instruments, and more. The manuscript also features an array of monsters, unicorns, animals, allegorical figures, and likely the first depictions of a bellows-driven pipe organ and a "green man" in the early Middle Ages.
