The first attestation is in a rather cryptic
kenning in stanza 10 of the
skaldic poem Glælognskviða by
Þórarinn loftunga, thought to date from 1030×34. In it, Þórarinn advises
King Svein Knutsson of Norway, encouraging him to pray to his predecessor,
Olaf II of Norway; the poem is among our earliest evidence for Olaf's status as a saint in Norway. One of the exhortations to Sveinn to pray runs ::þás þú rekr ::fyr reginnagla ::bóka máls ::bænir þínar which appears literally to mean 'when you perform/present your prayers in front of the sacred nail(s) [
reginnagla] of the language/speech/measure/inlaid decoration of books'. The main interpretations of the phrase 'reginnagla bóka máls' have been: • 'altar' or 'shrine' (taking the 'sacred nails of the language of books [i.e. Latin]' as a metonymy for the whole object) • 'priests' or 'St Olaf' (taking the 'sacred nail(s) of the language of books [i.e. Latin]' as a kenning either for priests generally or Olaf specifically) • 'liturgical book' (taking the 'sacred nails of the language/inlaid decoration of books' to refer to an ornamented book cover). Of these, 'Olaf' has historically been the most common and 'liturgical book', suggested by
Margaret Clunies Ross, the most recent (as of 2014). ==
