Reginnaglar
Reginnaglar is a word occurring twice in surviving Old Norse writings. Its meaning is unclear but it is a compound of reginn, "powers/rulers/gods/sacred" and naglar, "nails". Despite its rarity, the word has occasioned quite extensive scholarly debate because it may give insight into Old Nordic religion.
''Glælognskviða''
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 runswhich appears literally to mean 'when you perform/present your prayers in front of the sacred nail of the language/speech/measure/inlaid decoration of books'. The main interpretations of the phrase 'reginnagla bóka máls' have been:
- 'altar' or 'shrine'
- 'priests' or 'St Olaf'
- 'liturgical book'.
''Eyrbyggja saga''
The other attestation of reginnaglar is in the Icelandic saga Eyrbyggja saga, which relates the use of reginnaglar in the construction of a temple by Þórólfur Mostrarskegg :Here, the nails clearly represent some kind of metal, nail-like decorative feature of the high-seat pillars, and Clunies Ross sees it as plausible that despite the lateness of the source, it does represent a feature of pre-Christian material culture.
