The herd, about two thousand in number, rushed down the steep bank into the lake and were drowned.
(Mark 5:13b)
[460] should be lightened of the woes which good-for-naught Noman has brought me.’ “So saying, he sent the ram forth from him. And when we had gone a little way from the cave and the court, I first loosed myself from under the ram and set my comrades free. Speedily then we drove off those long-shanked sheep, rich with fat, [465] turning full often to look about until we came to the ship. And welcome to our dear comrades was the sight of us who had escaped death, but for the others they wept and wailed; yet I would not suffer them to weep, but with a frown forbade each man. Rather I bade them
(Odyssey 9:464-465)
Now, I think that in Marcion's Gospel, the herds of pigs running down the rocky cliff to the sea was absent. It can be a Judaizing interpolation to make Jesus a punisher of the pigs/demons, whereas in the Marcion's gospel the point was that Jesus was so Good (as Son of the Good God) that he has the demons escape freely in the pigs without giving them a punition shortly after. The pigs, as symbol of lower matter, were the creatures of the demiurge, hence it is just that the demons entered in them without die.
Even so, I think that here the author of the episode was really basing himself on Homer. It is the only point in all Mark where I concede really this point.
But I think that a more faithful and coherent midrash from Homer doesn't assume the punition of the pigs/demons.
In Homer, the fact that the warriors were able to escape by masking themselves under the pigs (hence, the fact that they save themselves), is not meant as the prelude of a coming punition, shortly after, of these same warriors/"pigs". The sea allegorizes for them the complete salvation from Polyphemus.
This is more expected if the original midrash from Homer (in this precise point) was made not by "Mark" (judaizer) but by Marcion or by a proto-marcionite (Satornilos, Cerdon, etc), insofar the demons are able to save themselves without receiving a punition for their successful act of fugue.
To think that the demons7pigs drowned in the lake as punished by Jesus would be equivalent to think that Polyphemus punished the warriors of Odysseus when they reached the sea. Polyphemus would work as the blind demiurge, here.
Hence, the Gospel of Marcion read probably so:
26 And they sailed down to the country of the Gadarenes,
which is over against Galilee.
27 And when he went forth to land,
there met him out of the city a certain man,
which had demons [a] long time, and wore no cloke,
neither abode in a house,
but among the tombs.
28 When he saw Jesus, he cried out, and fell down before him,
and with a loud voice said,
What have I to do with thee, Jesus, thou Son of God most high?
I beseech thee, torment me not.
29 (For he had commanded the unclean spirit to come out of the man.
For oftentimes it had caught him: and he was kept guarded and bound
with chains and in fetters; and he brake the bands asunder,
and was driven of the demon into the deserts).
30 And Jesus asked him, saying, What is thy name?
And he said, Legion: because many demons were entered into him.
31 And they besought him that he would not command them
to go out into the abyss.
32 And there was there an herd of many swine feeding on the mountain:
and they besought him that he would allow them to enter into them.
And he allowed them.
