The Godescalc Evangelistary or Godescalc Gospel Lectionary, an illuminated manuscript Gospel Book written by the Frankish scribe Godescalc, was commissioned by Charlemagne and his wife Hildegard and produced in the court scriptorium at Aachen. The manuscript was intended to commemorate Charlemagne's march to Italy, his meeting with Pope Adrian I, and the baptism of his son Pepin. The manuscript's dedication poem credits the work to Godescalc, and includes details of Charlemagne's march to Italy. The manuscript is preserved in the Bibliothèque nationale de France (NA. lat. 1203).
A product of the Carolingian Renaissance, the Godescalc Evangelistary is the earliest example of the Carolingian Illumination Style. "This style was characterized by naturalist motifs in the decoration, and a fusion of the Insular, early Christian (late Classical) and Byzantine styles. The artist used natural illusionism techniques to create the appearance of volume in the characters, and used elaborate shadings in light and dark to give characters depth. The Carolingian illumination style was the earliest style to regularly utilize minuscule script, the precursor to our modern lower case letters" (Wikipedia article on Godescalc Evangelistary, accessed 11-25-2011).
