Calm Down Mother (1966) is one of Megan Terrys most popular feminist plays and addresses the significance of womens autonomy of mind and body in establishing a feminine subject. This research attempts to present Terrys transformation technique in challenging and criticizing the notion of women as mere objects which is established by masculine-oriented theories of different disciplines while echoing the views of various feminist critics from the three main strands of feminist criticism: American, British and French. The current study demonstrates the procedure of Terry subverting traditional images of women in literature: where male writers glorify womans youthful fertility through natural imagery, Terry emphasizes how these images further support and encourage a passive existence for woman. She refutes the patriarchal notion that there can only be a single subject, which is masculine, by introducing female characters that serve as examples of feminine subjects as opposed to passive objects and provides a real-life example through the fictional portrayal of Margaret Fuller. The paper depends on feminist views regarding the Subject/object binary with reference to the play and addresses the treatment of women as bodies merely valued for their beauty and youth along with womens complicity in perpetuating the patriarchal systems which deny womens autonomy.
