Then old Þorbjörn begins to speak: ‘It’s this way, Master
Odd,’ he said, ‘that you have promised me your help, and I
now want to have recourse to it, in that you contribute some
good advice and help me.’

It could be ‘to be of value’, but I think that ‘to help,
avail’ is at least as good. Either way the general idea is
clear, though.

> Oddur kvaðst svo gera mundu.

> Oddr said for himself (that he) would do so.

> Oddr declared-of-himself (that he) would do so.

Odd said that he would do so.

They ride now to Örnólfsdal and reach there before daybreak.

The houses were then fallen and the fire almost burnt out.

This is <mjök> Z3; <fölskaðr> 'pale, burnt out' is in CV.

> Nú ríður Oddur að húsi einu því er eigi var allt brunnið.

> Oddr now rides to one house that is not all burned.

> Now Oddr rides to that one (particular) building which is

Now Odd rides to the one house that was not completely
burned up.

He reaches out to a birch rafter and jerks it away from the
house, then rides widdershins about the houses with the
burning brand and said: ‘Here I take possession of land for
myself, for I do not see here now an inhabited homestead.

> Heyri það vottar þeir er hjá eru."

> He heard they affirm who were next to (him).

Let those witnesses hear that who are nearby.’

<Heyri> is 3rd plur. pres. subjunctive; its subject is
<vottar þeir>. German has a similar construction:

Sei X ein topologischer Raum.
Let X be a topological space.

Here <sei> is 3rd sing. pres. subj. of <sein> 'to be'.

> Hann keyrir síðan hestinn og ríður í brott.

> He then lashes his horse and rides away.

> He whips after-that the (his)-horse and rides away.

Then he spurs his horse and rides away.

There seems to be no telling whether he used a whip, spurs,
or some other means of driving the horse forward sharply.

> Hersteinn mælti: "Hvað er nú til ráða?

Herstein said: ‘Now what’s to be done?

> This turned out (ie proved to be) not good.”

This did not turn out well.’

Þorbjörn said: ‘Be silent if you can, whatever happens.’

Herstein replies and said that he has said only that which
was not too much.

I.e., no more than was appropriate.

> Útibúr var óbrunnið, það sem varningur Austmanns var inni

> A storehouse was not burned, that which the Norwegians'

A storehouse was unburned, that which the Easterner’s wares
were in, and much other wealth.

> Í þessu hverfur Þorbjörn karl.

> Earl Thorbjorn disappears in this.

> Old-man Þorbjorn turns (disappears) into this.

At this moment old Þorbjörn disappears.

I’m pretty sure that <Í þessu> is the adverbial expression
of time. Remember, this Þorbjörn is the fellow who
sometimes moves so fast that he isn’t where he’s actually
seen; I shouldn’t be surprised if ‘disappears’ were intended
literally.

> Nú lítur Hersteinn heim til bæjarins og sér útibúrið opið

> Herstein now looks home to his farms and sees the

> Now Hersteinn looks homeward towards the-farmstead and

Now Herstein looks homewards to the farmhouse and sees the
storehouse open and the wealth carried out, but he sees no
person.

> Þar eru bundnar klyfjar.

> There are bound packs there.

> There are bound trusses.

Packs are tied up there.

> There next he hears a great noise in the-home-meadow, sees

Thereupon he hears a great noise in the home field; he now
sees that all the horses that his father had owned are being
driven home, the sheep and cattle from the cowshed and all
the livestock.

> Síðan eru klyfjar upp hafðar og því næst öllu á ferð snúið

Then the packs are lifted up, and thereupon everything sent
on its way, and everything valuable carried away.

Baetke has <snúa á rás> 'to begin to move, to get under way;
to run off', to which this seems similar. See also some of
the glosses s.v. <snúa> in the Faulkes/Barnes yellow
glossary.

Herstein now goes after it and sees that old Þorbjörn is
driving the animals.
