Textual boundaries in Anglo-Saxon works on time (and in some Old English poems)

At Beowulf lines 1740 and 2039, and Genesis A, line 1248, section breaks fall before what is generally considered to be a conjunction – od pcet ‘until’. Else von Schaubert treated od pcet in these lines of Beowulf as an adverb and glossed them ‘da, alsdann, in der Folge’, ¹ and Bruce Mitchell has confirmed that od pcet may indeed be used adverbially, though he also cautions that it can be difficult to classify an individual instance as ‘conjunction’ or ‘adverb’ and that there may be ‘an intermediate stage’ covering some uncertain instances. ² Each of the three examples of od poet mentioned here can be read as an adverb, but each also can be read as marking the termination (or the imminent termination) of the condition stated in the preceding clause, thus meaning ‘until’. ³ At Exodus 107, moreover, someone (not certainly the poet) saw fit to begin section [xliv] at a place that is unambiguously the middle of a sentence, ⁴ raising the question whether the occurrence of a section break is in itself a sufficient indicator that a sentence has ended.
