Bragi

Bragi is the Norse god of poetry, music and scaldic arts. The poem Sigrdrífumál, found in the Poetic Edda, depicts Bragi as having runes carved on his tongue.
Bragi is renowned for his wisdom, and above all for his ability with words. He knows most of the warmth, which after him are called bragr, and from his name is called bragr, who has an eloquence greater than the others. His wife is Idunn. He is also the adviser of Odin in Valhalla and is the one who welcomes the warriors who enter it.
