Byggvir

Byggvir is a figure in Norse mythology. The only surviving mention of Byggvir appears in the prose beginning of Lokasenna, and stanzas 55 through 56 of the same poem, where he is referred to as one of Freyr's servants and as the husband of Beyla.

Bygg is the Old Norse word for barley. Subsequently, Byggvir is often identified with this etymology of his name and connections have been placed with the mentioning of Byggvir's described involvement with mill-grinding as being potential references to barley processing. Comparisons to the Anglo-Saxon figure of Beowa (Old English "barley") have been put forth.

Interpretation
In relation to Loki's comments in Lokasenna, proposals have been made that Beyla and her husband are personifications of agriculture associated with Freyr: Beyla as the manure that softens the earth and develops the seed, Byggvir as the refuse of the mill, chaff.
