Bragi is the skaldic god of poetry in Norse mythology.
Bragi is generally associated with bragr, the Norse word for poetry. The name of the god may have been derived from bragr, or the term bragr may have been formed to describe 'what Bragi does'. A connection between the name Bragi and Old English brego 'chieftain' has been suggested but is generally now discounted. A connection between Bragi and the bragarfull 'promise cup' is sometimes suggested, as bragafull, an alternate form of the word, might be translated as 'Bragi's cup'. See Bragarfull.
Snorri Sturluson writes in the Gylfaginning after describing Odin, Thor, and Baldr:
One is called Bragi: he is renowned for wisdom, and most of all for fluency of speech and skill with words. He knows most of skaldship, and after him skaldship is called bragr, and from his name that one is called bragr-man or -woman, who possesses eloquence surpassing others, of women or of men. His wife is Iðunn.
In Skáldskaparmál Snorri writes:
How should one periphrase Bragi? By calling him husband of Iðunn, first maker of poetry, and the long-bearded god (after his name, a man who has a great beard is called Beard-Bragi), and son of Odin.
That Bragi is Odin's son is clearly mentioned only here and in some versions of a list of the sons of Odin (see Sons of Odin). But "wish-son" in stanza 16 of the Lokasenna could mean "Odin's son" and is translated by Hollander as Odin's kin. Bragi's mother is possibly the giantess Gunnlod. If Bragi's mother is Frigg, then Frigg is somewhat dismissive of Bragi in the Lokasenna in stanza 27 when Frigg complains that if she had a son in Ægir's hall as brave as Baldr then Loki would have to fight for his life.
