It appears at fol. CCVIIr of Vat.lat.2671, a codex of law which has just been digitized at the Vatican Library. The book is the Summa super titulis decretalium of Goffred de Trano, compiled between 1241 and 1243 and this is a copy from just a generation later, scribed 1270/80, perhaps in Puglia, Italy. The image is part of an arbor, a scheme of forbidden in-law unions.
Goffred, according to Hermann Schadt passim, is the first to propose that this diagram is a tree: "Et quia in qualibet arbore, fructifera et naturali, quattuor, attendunt, truncus, rami, fructus et frondes. Et in hac arbore scripta eadem considerari oportet." Far fetched, as these matrices don't really look anything like trees, but the artist obediently paints a bird and a big frondy leaf.
On another folio, CCIVv, is the other model for the matrix, the placard-carrying man. Here is the head:
.. and here are the feet:
At first sight I thought that little face in the middle, like a joey in a kangaroo pouch, was the holder of the placard. In fact, look at for a while and you might even see a hang-glider here :-)
In all, 53 books were digitized last week, and here is the full list:

Manuscripts travelled in many ways, also as spoils of war: this beautiful #Carolingian compilation of #Roman #geography & #history was acquired by Napoleon during his Italian campaigns & retrieved only after the fall of the French Emperor— GiorgiaV (@ParvaVox) June 26, 2018
