The Homeric Helmet of Hades

But even if he should happen to lay hold upon them (= the followers of Mark), then they might simply repeat these words, while standing in his presence along with the "Redemption:" "O thou, who sittest beside God, and the mystical, eternal Sige, thou through whom the angels (mightiness), who continually behold the face of the Father, having thee as their guide and introducer, do derive their forms from above, which she in the greatness of her daring inspiring with mind on account of the goodness of the Propator, produced us as their images, having her mind then intent upon the things above, as in a dream,--behold, the judge is at hand, and the crier orders me to make my defence. But do thou, as being acquainted with the affairs of both, present the cause of both of us to the judge, inasmuch as it is in reality but one cause." Now, as soon as the Mother hears these words, she puts the Homeric helmet of Pluto upon them, so that they may invisibly escape the judge. And then she immediately catches them up, conducts them into the bridal chamber, and hands them over to their consorts. [Irenaeus Against Heresies 1.13.6]

And it was certainly better that the Child Jesus should escape the snare of Herod, and should reside with His parents in Egypt until the death of the conspirator, than that Divine Providence should hinder the free-will of Herod in his wish to put the Child to death, or that the fabled poetic helmet of Hades should have been employed, or anything of a similar kind done with respect to Jesus, or that they who came to destroy Him should have been smitten with blindness like the people of Sodom. [Origen Contra Celsum 1.66]
