The compound 'seyðabrævið' could perfectly well be translated
to 'södabrevet' to Swedish. The noun 'söd' for sheep in Swedish is a
little bit unusual, a more usual one would be 'får'. This would
give 'fårabrevet' instead. But 'söd' is the cognate to 'seyð', so I
prefer this as a translation to Swedish.
I quote Fröding (written 1883) here:

"Herrliga mö!
Ack, hvilka läppar!
Skäggstrån som käppar
Dum som en sö!"
