"Trusty John", "Faithful John", "Faithful Johannes", or "John the True" () is a German fairy tale collected by the Brothers Grimm and published in Grimm's Fairy Tales in 1819 (KHM 6). Andrew Lang included it in The Blue Fairy Book. It is Aarne-Thompson type 516. Others of this type are Father Roquelaure and The Raven. Antti Aarne and Stith Thompson catalogued about 500 tales under this type, of which over 200 were Irish, and the remainder, from the rest of Europe and European colonies in America. Such tales include In Love with a Statue, How to find out a True Friend, The Man of Stone, and Amis et Amiles. Origin The tale was published by the Brothers Grimm in the second edition of Kinder- und Hausmärchen in 1819. Their source was the German storyteller Dorothea Viehmann, from the village of Niederzwehren near Kassel. Synopsis In some variants, a king on his deathbed orders his servant, Trusty John, not to let his son see a certain room, which holds a portrait of a princess. In all variants, when the new king comes to power, he forces his way into the room. Instantly, he falls in love with the princess. In Joseph Jacobs's version, her country had been at war with his, and the portrait stems from betrothal negotiations that had fallen through; but in all versions, the king does not know how to win her. Trusty John tells him to prepare a ship with all manner of rich treasure, and then either sails with it himself, or has the king sail with him, to her country. The princess is lured aboard by the goods, and the ship sets sail, carrying her off. While they travel, John hears three ravens. One says that as soon as they reach shore, a horse will come; if the king mounts it, it will fly into the air with him, and neither will be seen again. The solution is for someone to kill the horse, but anyone who reveals this by stating it out loud would have his legs turn to stone up to the knees. The second raven says (with variations in different tellings) that the king would be killed by wine at the wedding feast if it were not dashed to the ground, or that he would be incinerated by a wedding shirt if it was not destroyed by a glove-wearing person, etc.; in
