The third entry for the Penn Parchment Project is MS Codex 1329, an Italian manuscript dated from between 1200 and about 1230. It is a commentary on the Song of Solomon. The shapes in the margins present the biblical lemmata in decorated circles and triangles, while the main text of the manuscript presents the commentary itself.
