Until the advent of modern historical criticism, few moments in the history of Christian exegesis have displayed the concern and respect for the Jewish interpretation of Scripture that are apparent in the works of the Victorines. Most notable for his willingness to accept Jewish opinions even on points which Christian tradition had universally accepted as Christological prophecy, Andrew of St. Victor, student of Hugh and colleague of Richard, has given modern scholarship a glimpse of the kind of Jewish-Christian dialogue that was taking place in mid-twelfth century Paris. The present edition provides an example of Andrew's more mature work, composed probably during his second sojourn at the Abbey of St. Victor, ca. 1155-1162.
The text of the Expositio super Danielem is accompanied by a number of apparatus. The apparatus criticus has been described above. The apparatus biblicus attempts to give some idea of the state of the biblical text used by Andrew.
The apparatus fontium gives references to standard printed editions, but it also includes references to the Glossae Gisleberti found in St. Omer, Bibl. mun., MS 220, ff. 1-29. This Gloss on Daniel appears to antedate Andrew's work, and stands near the point of origin for the text which became the Glossa Ordinaria on Daniel.
Given that the full impact of Andrew's work will not be known until the myriad of biblical commentaries of the twelfth and thirteenth centuries have been edited, another apparatus has been provided for the present edition which gives references primarily to thirteenth century works that cite Andrew. These are not properly testimonia, and there is no commonly used term to describe such an apparatus. It could perhaps be called an apparatus debitorum; in any case, the references contained in it are indexed together with those of the apparatus fontium in the index auctorum.
