Rosalind is the daughter of the banished Duke Senior, and she is in love with Orlando, the son of Sir Rowland de Boys. Celia is the daughter of Duke Frederick, who has usurped Duke Senior's throne, and she is Rosalind's best friend. When Rosalind is banished from court, Celia decides to go with her, and they disguise themselves as men named Ganymede and Aliena.
In the Forest of Arden, Rosalind and Celia meet a variety of characters, including Orlando, Jaques, and Touchstone. Rosalind falls in love with Orlando, but she disguises her feelings for him in order to test his love. Celia supports Rosalind in her deception, and she helps her to bring about a happy ending for herself and Orlando.
Rosalind and Celia are both strong, independent women who are not afraid to challenge the status quo. They are also loyal and supportive friends who are always there for each other. They are two of Shakespeare's most well-developed and beloved female characters.
