Binding: Binding from the 15th c. typical for the Schaffhausen monastery.
History: Szkiet compared the meager book illumination there is (one initial on f. 42v), which, according to her, shows no similarities with the decoration from Schaffhauser. Unclear where it was produced. Borst noted as place of production (without argumentation) Saint Gall or Reichenau. The manuscript consists of two codicological units written and joined together probably in the same scriptorium. The main part contains Bede's De temporum ratione envisaged originally as separate book with quiremarks I-X. The first three quires were added later. — Borst argued the manuscript was in Schaffhausen already around 1050, where it served as the "komputistische Grundausstattung" of the monastery. Cordoliani noted that the manuscript is attested in the library of Schaffhausen from the 13th c. (see several ownership and loan-notes on f.104 "Hic liber est monasterii omnium sanctorum in Scaffusa", "Anno domini MCCCLVI [1356] in vigilia sancti Oswaldi regis accepi hunc librum de libraria nostra"). For later ownership notes see Gamper.

15r Short text on the planets: "Campester scribit cometas quinque esse id est ippon solis, lampadian lunae, ziphian martis, disceum martis, typhona saturni; sed quattuor stellas suprascriptas uisas esse aliquando cum regna mutuantur; typhonam numquam uisam esse, aut si quando uisa fuerit cuncta interitura."
15r-19v De signis coeli (missing cap. XLI) Helix arcturus maior habet autem in capite … — … et ideo anticanis uocatur eo quod contraria sit cani. Text written in one column, leaving blank space on the outer side of the pages probably for illustrations.
19v Excerptum de astrologia Duo sunt extremi uertices mundi quos appellant polos … — … et virginem leo[…] The quire is missing the innermost bifolium, after f.19, hence the lacuna at the end of the text.
20r-21r Dionysius Exiguus: Epistola ad Bonifacium et Bonum septimum communem, octauum embolismum The text begins imperfectly due to the missing bifolium after f. 19.
