As a predominantly Christian people, Westerners think they know the Bible pretty well. But not everybody realizes that many of the most iconic features of Christianity were never mentioned by the holy book or the church, but were actually pulled from the ass of some poet or artist years after God turned in his final draft of the Bible. Things like ...
The image of an angel is so recognizable that you can immediately spot one if somebody makes its shape in some snow. They're sparkly people with two white wings and occasionally swords, who sit on clouds ripping out awesome harp solos while protecting humans from harm. So basically, the protagonists of the next Stephenie Meyer novel.
The sex scene will be as unsettling as it is improbable.
The Only Problem Is ...
Now, there are angels in the Bible. But if you encountered some of the angels it describes, you'd probably need a shotgun under your bed to sleep soundly for the rest of your life.*
*NOTE: that is a joke. If angels turn out to be real, and you encounter one, do not shoot it with a shotgun.
There are several kinds of angels in the Bible and you've probably heard about some of them, like archangels, cherubim and seraphim. They all look different, and very few actually have wings. Those who do, like the seraphim, actually have six wings and need all of them to cover their body, lest they blind/incinerate whoever is unlucky enough to bump into one.
This is a seraph, trying with all its might not to burn you alive.
Then there are the thrones, which are described in the Bible as "wheels within wheels," the rims of which are covered in eyes.
Whatever it is, we're pretty sure it can see.
Then we have the cutest order of angels, the cherubim. As we all know, a cherub is a baby angel, usually with a little bow and arrow and a leaf protecting his modesty. Except that Ezekiel 10:14 describes them as frightening four-headed monstrosities that included the faces of a man, an eagle and a lion.
Actually Came From:
Painters took liberties when portraying angels, and just like putting capes on superheroes, giving them wings was a visually interesting way to identify who was the angel in a painting full of regular dudes (wings were also used in the early church to denote that these creatures lived in the sky). Archangels like Michael and Gabriel were given contemporary military garb.
Which apparently included "hair like a lady."
Cherubs in particular didn't get their extreme makeover until Renaissance sculptors revived the ancient practice of putti, which depicted cute babies dancing and playing around on infant tombs. The rediscovery and reimplementation of these little cuties brought Cupid-esque cherubs into vogue, as demonstrated by Tomba di Ilaria del Carretto:
Whaddya know? Those dancing naked babies do make this tomb less unsettling.
Lastly, the thing about the harps was actually invented by John Milton who wrote about angels "plucking harps" in Paradise Lost, basically just because it was the cutest thing he could pull out of his ass.
