Esau's entire body is supposed to have been covered with red hair. King David is also known for having red hair, based on the description of his physical appearance as "admoni", the Biblical Hebrew word normally interpreted to mean "ruddy" and/or "red-haired" (1 Samuel 16-17).
Judas Iscariot is also represented with red hair in Spanish culture and in the works of William Shakespeare, reinforcing the negative stereotype. In Spain the prejudice is extended to so-colored cats and dogs.
Early artistic representations of Mary Magdalene usually depict her as having long flowing red hair, although a description of her hair color was never mentioned in the Bible, and it is possible the color is an effect caused by pigment degradation in the ancient paint. This tradition is used as a plot device in the book and movie The Da Vinci Code. Thor, of Norse mythology, was generally portrayed as having red hair. Another Norse God Loki, the mischievous god of fire was portrayed with red hair.
Ancient Egyptians associated both red-haired humans and red-colored animals with the god Set, considering them to be favored by the powerful and temperamental deity.
