Lokasenna – Loki's Wrangling

Loki spake:
36. “Give heed now, Njorth, | nor boast too high,
No longer I hold it hid;
With thy sister hadst thou | so fair a son,
Thus hadst thou no worse a hope.”

Tyr spake:
37. “Of the heroes brave | is Freyr the best
Here in the home of the gods;
He harms not maids | nor the wives of men,
And the bound from their fetters he frees.”

Loki spake:
38. “Be silent, Tyr! | for between two men
Friendship thou ne’er couldst fashion;
Fain would I tell | how Fenrir once
Thy right hand rent from thee.”

Tyr spake:
39. “My hand do I lack, | but Hrothvitnir thou,
And the loss brings longing to both;
Ill fares the wolf | who shall ever await
In fetters the fall of the gods.”

Loki spake:
40. “Be silent, Tyr! | for a son with me
Thy wife once chanced to win;
Not a penny, methinks, | wast thou paid for the wrong,
Nor wast righted an inch, poor wretch.”

36. Thy sister: the Ynglingasaga supports this story of Njorth’s having had two children by his sister before he came among the gods. Snorri, on the other hand, specifically says that Freyr and Freyja were born after Njorth came to the gods.

37. Tyr: the god of battle; cf. notes on Hymiskvitha, 4, and Voluspo, 39. Freyr; concerning his noble qualities cf. Skirnismol, introductory prose and note.

38. Snorri mentions Tyr’s incompetence as a peacemaker. Fenrir: the wolf, Loki’s son; cf. Voluspo, 39.

39. Hrothvitnir (“The Mighty Wolf”): Fenrir, who awaits in chains the final battle and death at the hands of Vithar. The manuscript has a metrical error in line 3, which has led to various emendations, all with much the same meaning.

40. Thy wife: there is no other reference to Tyr’s wife, nor do we know who was the son in question.
