You know, it's interesting to see the same theme revisited, using the same imagery, to a degree.
I have to say that when it had to do with the "Alchemical Union," nothing thus far has beat Dawn (II) for me, all the way back in day 14 of the challenge. That one didn't do with the "Crimson Child," as opposed to this piece, day 40's Upon Entry to My Sphere, and day 49's Risen. And yet we have different alchemical union pieces as well, such as day 44's Pass through the keyhole and receive the mystery.

Though I definitely thought you didn't need Risen, I'm glad you stuck around for this one, as from the three "Scarlet Child" ones, it's definitely my favourite. I'm curious if once it's all over you'll take these three poems and combine them, transmute them, into a singular whole, that is greater than the three aspects.
It's interesting to see how they differ.

This one definitely feels quite more poetic, especially with the imagery in the third stanza, that lets the images roll out, and breathe. This one says a lot less outright, and leaves more to imagination. Even if the imagery of the intercourse is quite strong in this one.

And the serpent, not dying in the flame, but seeding them, and you. And the child is a sacrifice. It's an interesting, for shouldn't the child be the result of the union? And if the child is the sacrifice, then what is it sacrified for?
And thus we go from the Molekh, with a child sacrificed in flame, to Jesus, with feeding on your flesh and blood.

And I can't help but read an invisible "delight," following the third stanza's last line.
Are you filling him with light, or with delight? And if he's the serpent, why are you the one who's now filling him with light? Because he fed you an apple, and you've got light and wisdom to share now? Hm.

And the final question is, why use "Babylon" as a tag? Almost feels as if it's a cheat, since it's not in the title, or the poem, or even in the shared imagery. Interesting.

P.S Speaking of the title, "Gluten of Eagle," the thing that brings the one who tries to rise high low? And yet feeds it? Somewhere between Icarus to Prometheus? That sure is a strangeness of a title ;-)
