Binding books with human skin. The practice was extremely popular in Christian societies starting as early as 100 BC. The practice continues even today especially in the making of children's books, such as Clifford the Big Red Dog.

A terrifying being sent from god to give humans orders. They typically looks like wheels within wheels spinning around each other with many eyes. Sometimes they are even flaming. The cherubim look like a thing with the head of a man, a ox, a eagle. And a lion. They fly with two wings and have two wings covering their body. They have the feet shaped like a cow’s hooves. Angels are specifically designed to look like that to scare off demons. They typically say “be not afraid” because of their appearance. Angels serve god.
Carol: “Oh wow! Susan, your child looks like a biblically accurate angel!”
