Symbolism of the Unicorn in the Glass Menagerie

Tennessee Williams uses many situations, characters and objects as symbols. Two of these objects are the glass menagerie and the glass unicorn. It can be said, because of the title of the play, that the glass menagerie is the central symbol and also due to its repeated appearance along the story. The collection of glass animals represents Laura’s nature because like the menagerie, Laura is delicate, unique and beautiful to those who know how to see her. As the menagerie, the unicorn has a lot of meaning because it particularly represents Laura due to its unusualness and loneliness and after it brakes, it shows how Laura changes.
When Tom fights with Amanda on scene three, Laura is present all the time and hears what they tell each other. Because of her fragile nature, she feels somehow hurt by their words even if it is not directly about her, when Tom goes infuriated, out of the house, and hits Laura’s collection with his coat, she shatters as the glass: “With an outraged groan he tears the coat off again, splitting the shoulder of it, and hurls it across the room. It strikes against the shelf of Laura’s glass collection, and there is a tinkle of shattering glass. Laura cries out as if wounded.”
Not knowing that the glass menagerie is the most important thing for Laura, no one minds it braking or pays attention to her when she cries out, also showing the arrogance and selfishness from the other characters:
“LAURA: [shrilly]: My glass!—menagerie…. [She covers her face and turns away.]

Also on the introduction to the scene, Laura is described as she receives the light from the new floor lamp while she is in the sofa: “The new floor
