Bobbio Orosius

It is thought to have been produced at the scriptorium of Bobbio Abbey, which was founded by Saint Columbanus in 612.

The monks gave the manuscript to the Ambrosian Library when it was founded in 1606 by Cardinal Federico Borromeo.

The smaller panels are composed of chevrons and triangles that alternate in pink and yellow.

The initial P and the opening words Praeceptis tuis par(rui) are many times larger than the rest of the text and are of hollow shafted capitals, with stem of the P descending the entire length of the text block.

There is also a larger initial N on folio 33 that has a cable pattern in white on orange in the uprights.
