But the great hero himself tossed and turned.
It was like a man roasting a paunch
Stuffed with fat and blood over a fire.
He can’t wait for it to be done
And so keeps turning it over and over.

[ἀτὰρ αὐτὸς ἑλίσσετο ἔνθα καὶ ἔνθα.
ὡς δ᾽ ὅτε γαστέρ᾽ ἀνὴρ πολέος πυρὸς αἰθομένοιο,
ἐμπλείην κνίσης τε καὶ αἵματος, ἔνθα καὶ ἔνθα
αἰόλλῃ, μάλα δ᾽ ὦκα λιλαίεται ὀπτηθῆναι,
ὣς ἄρ᾽ ὅ γ᾽ ἔνθα καὶ ἔνθα ἑλίσσετο]

But from side to side
It made him toss apace. You have not tried
A fellow roasting of a pig before
A hasty fire, his belly yielding store
Of fat and blood, turn faster, labour more
To have it roast, and would not have it burn,
Than this and that way his unrest made turn
His thoughts and body ....
[tr. Chapman (1616)]

He lay restlessly.
As one that has raw flesh upon the fire,
And hungry is, is ever turning it;
So turneth he himself ....
[tr. Hobbes (1675), l. 20ff]

Restless his body rolls, to rage resign'd
As one who long with pale-eyed famine pined,
The savoury cates on glowing embers cast
Incessant turns, impatient for repast.
[tr. Pope (1725)]

Yet he turn’d from side to side.
As when some hungry swain turns oft a maw
Unctuous and sav’ry on the burning coals,
Quick expediting his desired repast ....
[tr. Cowper (1792), l. 26ff]

But ever he rolled tossing to and fro.
As when a man beside a blazing fire
Turneth a rich fat goat-paunch to and fro,
Over and over, with intense desire
Quickly to roast it ....
[tr. Worsley (1861), st. 4]

But himself tossed to and fro.
As when a wight a'front a blazing fire
A savoury haggis full of fat and gravy
Restlessly turns and tumbles to and fro --
In hope right well and quickly for to roast it.
[tr. Bigge-Wither (1869), l. 24ff]

But, ev'n as when a man at some fierce fire
A savoury paunch with fat and blood replete
From side to side turns oft, intent with speed
Most prompt to roast it; -- so, from right to left
Ulysses swaying lay.
[tr. Musgrave (1869), l. 36ff]

But Odysseus himself lay tossing this way and that. And as when a man by a great fire burning takes a paunch full of fat and blood, and turns it this way and that and longs to have it roasted most speedily, so Odysseus tossed from side to side.
[tr. Butcher/Lang (1879)]

But he himself in meanwhile was tossing here and there.

A paunch of fat and of blood, and turneth it oft about
Hither and thither, all eager to roast it speedily.

[tr. Lawrence (1932)]

Odysseus nevertheless could not help tossing to and fro on his bed, just as a paunch stuffed with fat and blood is tossed this way and that in the blaze of the fire by a cook who wants to get it quickly roasted, twisting and turning thus to one side and the other ....

fire, and the pudding itself strains hard to be cooked quickly;
so he was twisting and turning back and forth.
[tr. Lattimore (1965)]

He himself kept twisting one way and the other. As when a man keeps shifting a paunch that has been stuffed full with suet and blood, in a huge fire's blaze, one way and the other turning it over, and wishes for it to be rapidly roasted, so did he twist one way and the other.

[tr. Wilson (2017)]
