He writes that Minos was the first master of the sea (protos thalattokratesai) and a good or zealous lawgiver (spoudaios nomothetes), and that he emulated his uncle Rhadamanthus
, who gave laws based on meetings with Zeus and thus civilized (exenerosai) Crete.
Zeus appoints as judges his own sons: two from Asia, Minos and Rhadamanthus, and one from Europe, Aeacus.
Is Socrates suggesting that Zeus' sons, Rhadamanthus, Aeacus, and Minos, are to be the afterlife substitutes of earthly witnesses?
(18) When they are disconnected, "each of them keeps its own condition very much as it was when the man was alive, the body having its own nature, with its treatments and experiences all manifest upon it." (19) At death the same will be true of the soul: "when a man's soul is stripped bare of the body, all its natural gifts, and the experiences added to that soul as the result of its various pursuits, are manifest in it." (20) When the souls arrive before Rhadamanthus, who is in charge of judging the souls from Asia, he will set them in front of him and examine them without knowing to whom they belonged in life.
True, Rhadamanthus does not know that the Great King is the Great King when he sees his soul.
We can notice first that Socrates does not say that Rhadamanthus will see the Great King's past actions.
While the Christian God is omniscient, Rhadamanthus and his brothers are not.
In order to have access to the soul of the Great King, Rhadamanthus must be able to abstract from his social mask.
To express this in yet another way, what Rhadamanthus is supposed to do is to detach the soul he is inspecting from its artificial extensions: its witnesses.
