Prose Edda — Old Norse facing a living language
Þá mælti Gangleri: "Miklir þykkja mér þessir fyrir sér æsirnir, ok eigi er undarligt, at mikill kraftr fylgi yðr, er þér skuluð kunna skyn goðanna ok vita, hvert biðja skal hverrar bænarinnar. Eða eru fleiri enn goðin?" Hárr segir: "Sá er enn áss, er Týr heitir. Hann er djarfastr ok bezt hugaðr, ok hann ræðr mjök sigri í orrostum. Á hann er gott at heita hreystimönnum.
Then Gangleri said: "These Aesir seem very powerful to me, and it's no wonder such authority follows you, since you clearly understand the gods and know just which one to pray to for which favor. Are there more gods still?" High said: "There's still one of the Aesir called Tyr. He's the boldest and most stouthearted, and he holds great sway over victory in battle — brave men should call on him.
Þat er orðtak, at sá er týhraustr, er um fram er aðra menn ok ekki sést fyrir. Hann var ok vitr, svá at þat er ok mælt, at sá er týspakr, er vitrastr er.
There's a saying that a man is 'Tyr-brave' when he surpasses others and never flinches; and he's also wise, so it's said that the wisest man is 'Tyr-prudent.' Here's one proof of his boldness: when the Aesir lured Fenris-Wolf into letting them put the fetter Gleipnir on him, the wolf wouldn't trust that they'd set him free again until they laid Tyr's hand in his mouth as a pledge.
Þat er eitt mark um djarfleik hans, þá er æsir lokkuðu Fenrisúlf til þess at leggja fjöturinn á hann, Gleipni, þá trúði hann þeim eigi, at þeir mundu leysa hann, fyrr en þeir lögðu honum at veði hönd Týs í munn hans, en þá er æsir vildu eigi leysa hann, þá beit hann höndina af, þar er nú heitir úlfliðr, ok er hann einhendr ok ekki kallaðr sættir manna
And when the Aesir refused to free him, he bit the hand off, at the place now called the wolf-joint — so Tyr is one-handed, and isn't called a peacemaker.
