Ivory of Saints Benedict, Thaddeus, and another saint

11th or 12th century, Venezia
Musée National de l'Age Médiévale, Paris

St. Benedict is at the top, identified by the inscription S[ANCTUS] BENEDICT[US] ABB[AS], "St. Benedict the Abbot."  His peaked cowl is like that seen in the 10th century fresco beneath San Crisogono in Trastevere, Rome.

The figure at the bottom with the forked beard is S[ANCTUS] THAD[DEU]S, i.e. the apostle Saint Jude Thaddeus, holding a book to represent his epistle in the Bible. The strongly forked beard is not a feature of other images of the saint that I have seen.

The inscription in the middle roundel begins with an S for "Sanctus" and continues with what could be NICOJA or NICOLA, with the letters HO on the other side.  He wears a chasuble with a Y-shaped orphrey, like Pope St. Gregory in a related piece. Apparently this is intended to signify a bishop.
