> Og er þeir voru á brott farnir kvað Þórarinn vísu:
> And when they were gone away, Thorarinn said this verse:
> And when they had gone away Thorarinn recited this verse.

And when they had gone away, Þórarin spoke this verse:

> Erat sem gráps fyr glæpi,
> (Erat?) as arrow's before a crime,
> (It?) is not as a storm for wicked,


> grund fagrvita mundar,
> a field fair-conscience
> a grassy plain fair knowledge of a woman’s dowry,


> fúra fleygiáru
> fire's make fly
> they threw fire


> frænings lögum ræni
> (frænings?) laws pillage
> ?? bereft of laws


> ef sannvitendr sunnu,
> if truly-wise (?) sun,
> if knowing truth under? the sun,


> sé eg þeira lið meira,
> I see their more people,
> I be more of their help


> oss megni goð gagni,
> God can help us,
> god be able to be of use to us


> Gauts þekju mig sekja.
> Odin's thatch fines me
> brags they recognize sentence me to outlawry.

Esat sem gráps fyr glœpi,
grund fagrvita mundar!
fúra fleygiǭru
frænings lǫgum ræni:
ef sannvitendr sunnu
(sék þeira lið meira)
oss megni goð gagni,
Gauts þekju mik sekja.

Is not as if for misdeed sleet-storm's,
Green field of hand's fair beacon,
throwers of fires/sparks
of spear by means of law rob:
if true-knowers of sun
(I see their greater host)
(To us with might may gods be of use)
of Gaut's roof sentence me.

The <-at> of <esat> ~ <erat> is the negative particle.

Hand's fair beacon is gold, and its green field is a woman.
There's some question about the meaning of <fleygiǭrr>
(later <fleygiárr>); I've gone with 'thrower', but I've seen
interpretations based on <árr> as 'servant'. <Fræningr> is
apparently 'snake' whence poetically 'spear', and <fúrr>
'fire' might better be translated 'spark' here, so that the
whole kenning is apparently <frænings gráps fúra fleygiǭrr>
'spear's sleet-storm's sparks' thrower', where 'spear's
sleet-storm' is 'battle', it's sparks are arrows, the the
thrower of arrows is a warrior. <Ræni> is a subjunctive
whose subject has been omitted.

<Gautr> is one of Óðin's bynames, and his roof is Valhalla;
its sun is a shield, and a true-knower of the shield is (you
guessed it!) a warrior.

It is not as if they rob warriors [apparently Þórarin &
Co.] for a misdeed, woman, if warriors sentence me; I see
their greater host; may gods aid us with might.

It's possible that it should be arranged a bit differently:

It is not as if they rob warriors [apparently Þórarin &
Co.] for a misdeed, woman; if warriors sentence me -- I
see their greater host -- may gods aid us with might.

Snorri goði rode up along [the] ridge to Hrísar and so to
Drápuhlíð, and in the morning out to Svínavatn and so to
Hraunsfjörð and thence, as the way lies, out to Tröllaháls
and did not stop the journey before Salteyrarós.

And when they came there, some kept watch over the
Easterners [i.e., to keep them from interfering with the
burning of the ship], and some burned the ship, and so
Snorri and his men rode home, having done all this ['that
all this was done'].

> Arnkell spyr þetta, að Snorri hefir brennt skipið.
> Arnkell learns this, that Snorri has burned the ship.
> Arnkell learns this, that Snorri has burned the ship.

Arnkel learns this, that Snorri has burned the ship.

Then they went aboard a ship, Vermund and Þórarin with some
men, and rowed west along the fjord to Dögurðarness.

Hvammsfjörður runs east-west, so <um> here must be 'along'.

> Þar stóð skip uppi er Austmenn áttu.

> There the ship that the Norwegians owned was left

> There a ship was laid up which Easterners owned.

Laid up ashore there was a ship that Easterners owned.

> Þeir Arnkell og Vermundur keyptu það skip og gaf Arnkell
> Þórarni hálft skipið en Vermundur bjó sinn hluta.

> They, Arnkell and Vermundr, bought the ship and Arnkell

> They, Arnkell and Vermund, bought the ship and Arnkell
> gave Thorarinn half the ship and made (over to) Vermund

They, Arnkel and Vermund, bought the ship, and Arnkel gave
Þórarin half the ship, and Vermund prepared his share for
the journey.

Grace: <Vermundur> is nominative, so it must be the subject
of <bjó>.

> Þeir fluttu skipið út í Dímun og bjuggu þar.
> They moved the ship out to Dimun and resided there.
> They conveyed the ship out to Dimun and stayed there.

They moved the ship out to Dímun and stayed there
[presumably while making ready for a long voyage].

Dímun is a small island southwest of Dögurðarness.

> Sat Arnkell þar við til þess er þeir voru búnir og fór
> síðan með þeim út um Elliðaey og skildu þar með vináttu.

> Arnkell stayed there with (them) until they were ready and

> parted there with friendship.

Arnkel stayed there with [them] until they were ready and
then went with them out past Elliðaey, and there [they]
parted in friendship.

Elliðaey is a large island at the mouth of Hvammsfjörður.
I'm not sure of the precise sense of <um> here. It would
help to know how Arnkel got home; my best guess is that he
took ship from the harbor at Elliðaey, in which case <um>
might even be understandable as 'to'.

> Sigldu þeir Þórarinn á haf en Arnkell fór heim til bús

Þórarin and his companions put to sea, and Arnkel went home
to his estate, and in public opinion this assistance came to
be reckoned the finest.

Snorri goði went to [the] Þórsness þing and prosecuted
['supported, maintained'] his cases.

> Varð Þórarinn þar sekur og allir þeir er að vígum höfðu
> verið en eftir þingið heimti Snorri sér slíkt er hann fékk

Þórarin was outlawed there, and all those who had been at
the slayings, and after the þing Snorri appropriated to
himself such as he could get ['got'] of [their] confiscated
property, and so these cases ended.
