By the 13th century medieval theologians had a vast tradition of Christian writing upon which to draw in their exploration of the Bible's meaning. One way in which they coped with the task was to organise excerpts from the basic writings of authors such as Augustine and Jerome as in either a frame-like arrangement around the page of Biblical text or in a wide margin beside it. Usually notes were added between the lines as well. The selection of excerpts became standardised in a form called the 'glossa ordinaria'. This copy of the Pauline and Catholic Epistles from Rochester Priory has an 'amplified' version of the glosses. A from the Pauline Epistles shows the arrangement, with gloss in the left margin, the biblical text in larger and more widely spaced writing with decorated and coloured first letter of 2 Corinthians and the gloss between the lines in black ink and smaller writing.
