[4][5] The Brothers Grimm noted its close similarity to the Norwegian The Old Dame and Her Hen,[6] also grouped in this tale type.
Eventually, the sorcerer leaves but not before handing her the keys to all the rooms in the house and an egg to look after that was to be on her person at all times.
Ultimately, the sister did investigate the forbidden room out of curiosity and discovered a basin of blood at its center.
Once back home, the sorcerer could tell by the bloodied egg that the sister had gone against his will in his absence and had her suffer the same fate as the others from the room.
Unbeknownst to the sorcerer, the voice that would scold him whenever he tried to take a break on his journey came from one of the two sisters hidden inside the gold-brimmed basket and not his bride.
Along her way, she is addressed as "Fitcher's Bird" by passing guests to the wedding and the sorcerer returning from his delivery and asked of the whereabouts of the bride.
Regarding the meaning of Fitcher, the Grimms wrote in the notes to the tale that "The Icelandic fitfuglar (swimming-bird), which looked as white as a swan, will help to explain Fitcher's Vogel,"[6] and although this "swan" theory was endorsed by Albert Teodor Lysander [sv],[9] later commentators merely gloss fitfugl as "web-footed bird," which is the Cleasby-Vigfusson dictionary definition.
[10][11] Others scholars advocate the view that the word derives from German Feder "feather" or Fittich "wings".
