Professor José Carracedo Fraga has just published a volume in the prestigious Corpus Christianorum collection (# 115C) published by the Belgian publisher Brepols containing a critical edition and study of the Latin grammatical treatise by the Visigothic teacher and bishop Julian of Toledo (ca. 644-690). This grammatical treatise is the most complete preserved work from the Visigothic school, as it includes all the main fields of study defined by the grammatical tradition of Late Antiquity. It is also one of the first and best examples of the process of Christianization of Latin grammatical theory that took place in the medieval school. As is often the case with school texts, the work has survived in a double recension, and the volume offers the Latin texts of both versions side by side.
