type 510A is a female persecutor: in Fair, Brown and Trembling and Finette Cendron, the stepmother does not appear at all, and it is the older sisters who confine her to the kitchen. In other fairy tales featuring the ball, she was driven from home by the persecutions of her father, usually because he wished to marry her. Of this type (510B) are Cap O' Rushes, Catskin, All-Kinds-of-Fur, and Allerleirauh, and she slaves in the kitchen because she found a job there. In Katie Woodencloak, the stepmother drives her from home, and she likewise finds such a job. In La Cenerentola, Gioachino Rossini inverted the sex roles: Cenerentola is mistreated by her stepfather. (This makes the opera Aarne-Thompson type 510B.) He also made the economic basis for such hostility unusually clear, in that Don Magnifico wishes to make his own daughters' dowries larger, to attract a grander match, which is impossible if he must provide a third dowry. Folklorists often interpret the hostility between the stepmother and stepdaughter as just such a competition for resources, but seldom does the tale make it clear. In some retellings, at least one stepsister is somewhat kind to Cinderella and second guesses the Stepmother's treatment. This is seen in Ever After, the two direct-to-video sequels to Walt Disney's 1950 film, and the 2013 Broadway musical. Ball, ballgown, and curfew The number of balls varies, sometimes one, sometimes two, and sometimes three. The fairy godmother is Perrault's own addition to the tale. The person who aided Cinderella (Aschenputtel) in the Grimms's version is her dead mother. Aschenputtel requests her aid by praying at her grave, on which a tree is growing. Helpful doves roosting in the tree shake down the clothing she needs for the ball. This motif is found in other variants of the tale as well, such as in the Finnish The Wonderful Birch. Playwright James Lapine incorporated this motif into the Cinderella plotline of the musical Into the Woods. Giambattista Basile's Cenerentola combined them; the Cinderella figure, Zezolla, asks her father to commend her to the Dove of Fairies and ask her to send her something, and she receives a tree that will provide her clothing. Other variants have her helped by talking animals, as in Katie Woodencloak, Rushen Coatie, Bawang Putih Bawang Merah, The Story of Tam and Cam, or The Sharp Grey Sheep—these animals often having some connection with her
