The miniatures in the Stuttgart Psalter reflect the text in its totally direct sense, and thus give the Carolingian manuscript a special status, along with the Utrecht Psalter. Felix Heinzer undertakes a detailed examination of the functional connection behind this form of illustration. In the process, he also incorporates the Carolingian striving for valid texts together with contexts of apotropaic usage.
