Bluebeard, the fitcher's bird and the robber bridegroom are all versions of bluebeard.
All three tales deal with a women marrying or intending to marry a horrible man. All the men are horrible because they are criminals. However not all the men are the same, in bluebeard the man is rich and ugly because he has a bluebeard, in the fitcher's bird the man is a sorcerer and in the robber bridegroom the man is a prince.
The men also take different approaches in how they wanted to kill their ladies, in the robber bridegroom he wanted to cook and eat the princess, in the fitcher's bird he wants to kill his lady by chopping her into pieces just as he did to her 2 older sisters, and in bluebeard he planned to kill his wife by slitting her throat.
All the women saved themselves the princess from the robber bridegroom left and went back to tell her father when all the men were sleeping, in the fitcher's bird the woman pretended as if nothing was wrong as she plotted to have him killed and she also brought her 2 sisters back to life, and in blubeard the wife pleaded for her life as she waited to be saved by her brothers.
All tales ended with death but it much different ways. In the robber bridegroom the prince and all his fellow robber were executed, in the fitcher's bird the husband to be and all his wedding guest were burned alive in his house and in bluebeard his wife’s brothers killed him.
Only the fitcher's bird and bluebeard included the secret room with dead bodies and the bewitched blood stains. But still all women faced bad men be it a murderer or a robber they were all bad.
These tales are unique because they involve husbands that are not the kinds women would like to marry, the reader is exposed to the dark sides of these men and instead of the tales ending in marriage they end in murder.
I liked the fitcher’s bird the most because I have 2 sisters, so its more relatable and I loved that she was able to bring her sisters back to life and save the day.
