Odin (Norse god featured in the poem, Hávamál)
“Quite enough baseless blather comes
from the man never silent;
a quick tongue, unless it’s held in check,
often talks itself into trouble.”
- This quote comes from stanza 29 of Hávamál (Sayings of the High One), an old poem which was preserved in the 13th-century Poetic Edda which was produced anonymously in Iceland. The translation is by Carolyne Larrington (Oxford University Press, 2014).
