Bragi

Son of Odin and Frigga, Bragi was the most eloquent and well-spoken of the Gods. He was the patron of poetry, music, literature, wit and humour. He supposedly had runes carved into his tongue, which brought him his inspiration. His beloved wife was Idunn, the Goddess of youth and beauty. Bragi is often called up at Valhalla to entertain with song and story. Poetic inspiration in men came from drinking Bragi's 'mead of poetry'

In Nordic culture, oaths were sworn with a drink from the Bragarfull (Bragi's Cup), but Bragi himself had no such goblet according to any of the myths.

Because of a lack of mention in Norse myth, some have concluded that Bragi was actually a part of Odin's own personality, rather than a separate being of his own. Another theory is that Bragi was a mortal poet from the 9th century, whose reputation was so great that he was written into later stories and raised to God status.
