Excerptum de astrologia

De ordine ac positione

Parchment Lagen: The manuscript constist of at least two codicological units as becomes clear by the different quire marks. In the first part O (f.8v), P (f.16v), Q (f.24v), R (f.32v), S (f.38v), T (f.46v) and V (f.54v); in the second part I (f.82v), II (f.88v), and III (f.96v). Consequently a tentative formula for the second part (with the Aratea texts) would look like as follows: I6 (ff.77-82), II7-1 (ff.82-88, missing one after f.83), III8 (ff.89-96), IV4-1 (ff.97-99, missing one after f. 99). Missing at least two folia (after f.83 and f.99). Damage by ff. 88, 94 and 97 (partially cut or torn). Caroline minuscule.

Herkunft: This manuscript was once part of a larger MS produced in Tours. In its original form it consisted of 20 mostly quarto-quires of parchment, with quire-marks on the verso of the last folio - A to V. This MS is currently divided into 4 parts:

Bede, DNR and varia on the computus; Tours, Saint-Martin, 334 (49 fols.): Quires D, E, F and the first 6 folios from quires G and 7 last folios from quire H, quire I, and 4 folios signed K; Paris, BnF, nouv. acq. lat. 1613 (23 fols.): The last two folios of quire G and the first folium of quire H, quires L, M and N. Melange about the computus, the chronology, astronomy, the weights and measures. Paris, BnF, nouv. acq. lat. 1614 (99 fols.): Quires O to V ; 99 fols. Arithmetic of Boethius, followed (in a separate codicological unit) by Aratea.

It contained most probably the illustration usually attached to Involutio spherae of a globe on five columns. This was most probably a singleton, since there is no text missing between ff. 87 and 88, where one sees only the stub with which the folio was attached to the binding. (84r-93v) Vertices.

The text was probably accompanied by a depiction of the planisphere on 94v, which was later cut out, leaving a large circular hole in the middle of the folio. This caused also text damage on the recto.

The text ends up with the section on the constellation Navis missing the last nine constellations, which probably fitted one folio (Hydra, Corvus and Crater depicted together), thus making the last quire a quarto.
