Frá dauða Sinfjǫtla

Frá dauða Sinfjǫtla (Old Norse "On the death of Sinfjǫtli") is a short prose piece found in the Codex Regius manuscript of the Poetic Edda. It describes the death of Sinfjǫtli, son of Sigmundr, connecting Helgakviða Hundingsbana II and Grípisspá.

Borghildr, wife of Sigmundr, wanted Sinfjǫtli, her stepson, dead, as Sinfjǫtli had killed her brother. Now it is said, that Sigmundr was so tough, that he could withstand any kind of poison, but his sons could only tolerate it on their skins. Borghildr gave them ale, which Sinfjǫtli recognized as poisoned. He excused himself for two rounds, but when she brought him the third horn, his father, now drunk, said: "Let your beard filter it, son!" Sinfjǫtli drank and died at once.

The piece is normally published in editions of the Poetic Edda.
