Hans Christian Andersen said this quote

“ Then little Gerda said the Lord's Prayer; the cold was so intense that she could see her own breath; it came out of her mouth like smoke. Her breath became thicker and thicker, and took the form of little angels who grew larger and larger as soon as they touched the ground. All had helmets on their heads, and lances and shields in their hands; their numbers increased, and when Gerda had finished her prayer a whole legion stood around her. They trust their lances against the horrible snow-flakes, so that the latter flew into a hundred pieces; and little Gerda went forward safely and cheerfully. The angels stroked her hands and feet, so that she felt the cold less, and she hastened on to the Snow Queen's castle. ”
