›Expliciunt capitula libri huius scripti‹

(23v-) ›In nomine dei summi incipit astronomia et partes compotatio‹ Inter astronomiam autem et astrologiam aliquid differt … — Starts with an introduction based partly on Cassiodore, Institutiones II, 7 – on astronomy what it is, what are the topics covered by it. Added as first chapter to it Isidore’s rendering of the differences between astronomy and astrology and the phenomena which are treated. For providing the general cosmological framework, the definition of ‘mundus’, the compiler preferred Isidore’s rendering instead of that of Bede. Bede placed more attention on the elements and the vertical possition with earth floating over water, covered by air and fire at the outmost layer. Isidore on the contrary provided a more geographical description of the world, pointing to the fact that it is always in motion and naming the four climata. Bede followed Genesis for his account of the world, its’s elements and parts. The fragments used by Pliny – that the world is in motion, as it hangs suspended

26v-30v Ps. Bede: De signis caeli Helix arcturus maior habet autem in capite … — … eo quod contraria sit cani.

54v-56v Gregory of Tours: De cursu stellarum ratio ›Stellarum cursus per XII mensibus et tempora et horis‹ Stellarum cursus hoc modo obseruandus est … — … sigibertus rex obiret crinnita multos apparuit.
