Luciana is Adriana’s sister, and dwells with her and Antipholus of Epheseus.
She can preach on the natural submission of women to men as well as anyone, and tries to calm her sister down when she grows impatient with her husband. However, she does not scruple to tell her brother-in-law off, nor to insult the servants. She also advises Antipholus of Syracuse to at least pretend to still love his wife if he doesn’t. She is unnerved to suddenly find herself courted by him, and to swear him swear that he is unmarried. Convinced that he is mad, she becomes both pitying and terrified of him. She defends her sister’s actions to the Abbess, and recommends to Adriana to beg the Duke for help. Once all the confusions are sorted out, it is understood that she will be properly wooed by Antipholus of Syracuse.
