• Possibly written in Brittany

While this MS was in all likelihood produced in a 'Celtic' writing centre, its precise origin remains elusive. Bischoff (1960: 229) drew attention to the mixture of insular and Carolingian traits in the script of at least some of the numerous hands detectable herein, and in his view this fact points to an origin in Western Britain (Wales or Cornwall) or Brittany. Moreover, Wunderle (1995: 232–3) added that some of the hands may betray Anglo-Saxon influence and argued that some abbreviations found at fols 1r–62r (containing several works by Isidore of Seville) may point to the use of an exemplar from Iberia (in relation to this point, cf. also Bischoff 1960: 229). Unfortunately, for the moment there does not seem to be enough evidence to attribute this MS to a specific geographical area, although the simultaneous presence of insular and Carolingian features in the script means that Brittany remains a credible option.

Significantly, excerpts from the (Hiberno-Latin?) Prouerbia Grecorum occur among the Testimonia diuinae Scripturae that occupy fols 63r–99v (for the details and relevant bibliography, see Wright 2006: 195, 197–8; for further points of contact with Hiberno-Latin texts, see McNally 1961: 313). An interesting reference to the fifteenth year of the reign Dagperti regis ('of King Dagobert', undoubtedly Dagobert I) as nunc (i.e. the present year = AM 5845) can be found in a section titled De mundi annositate—a chronology of the six ages of the world—at fol. 65r: this passage, which may have been part of the prologue to the Testimonia (a text also found in the Florilegium Frisingense in Munich, BS, Clm 6433, a MS written at Freising in the late eighth century by the Anglo-Saxon scribe Peregrinus; cf. Lehner 1987: 44; Wright 2006: 197–8, n. 19), can be dated accordingly to AD 644 (the years of Dagobert's reign are counted here from the death of his father Clothar II in AD 629/630, and this means that Dagobert's death may have to be redated, probably to AD 646, as has been pointed out to me by Immo Warntjes in private correspondence). This chronology is followed (fols 65r–65v) by (1) a simple account of the regulae mensium (listing which months have 30 or 31 days, etc.) and (2) a mention of the growth of the bissextus from the superfluous three hours in each year (CCCLXV dies et III horas in anno de quibus tribus oris per quattuor annos crescit dies unus / et inde sit [sic, for fit] bisextus qui in mense martio addetur quia mensis martius per tres annos XXX et unum diem habet in quarto uero XXX duos). This short computistical text (which is probably unrelated to the previous passage containing the dating clause for AD 644; for a similar textual association, cf. Fulda, Hochschul- und Landesbibliothek, MS D 1, fols 181r–182r) contains some interesting features: in particular, both the idea of a bissextile day of 12 (rather than 24) hours and its placement in March can be found prominently in Irish computistical texts (cf. e.g. Warntjes 2010: 120–1, 130–1); indeed, Bede took an explicit stance against the former view in De temporum ratione, 39.10–12 (cf. also Einsiedeln, Stiftsbibliothek, MS 321 (647), p. 105, ll. 2–4). Moreover, the explicit mention of a duration of 32 days for the month of March when including the bissextus is extremely rare: so far, I have only come across it in the Computus Hibernicus Parisinus of AD 754 preserved in Paris, BnF, Lat. 6400B, fol. 276v (with some excerpts surviving also in Angers, BM, MS 476), where, however, the anonymous author uses this datum to argue against a March placement of the bissextile day.
