Hermione, the perfect picture of innocence, chastity, and obedience, is representative of how women were expected to be. In the trial, however, she is made out to be exactly the opposite. Leontes falsely accuses her of treason and adultery, something the audience knows she is innocent of. In general, I believe that this scene perhaps demonstrates that women have been conceived of unfairly in history and in Shakespeare's day, and Hermione's and Paulina's lines give women the voice that they have been forbidden them for centuries. This is particularly interesting since eventually it is proven that Hermione is innocent, showing her true fidelity and obedience to the king.
Paulina's character was also very important to this scene, I believe. Once Hermione has died, there must be someone to defend the cause of women, and so Paulina rebukes the king for his actions (listing the people that have died or suffered because of him), and her speech includes some of the most powerful lines of the scene:
But, O thou tyrant!Paulina tells it like it is, and receives no punishment for speaking her mind. She is told to be silent by a member of the court, and she herself immediately apologizes for the outburst, but no other punishment is inflicted. I feel that Paulina's speech and her sudden silence are also examples of how women's voices have been oppressed throughout history. She told nothing but the truth, something the king acknowledges when he states that "Thou didst speak but well When most the truth." However, although both she and Hermione spoke well, they were also eventually silenced.
Do not repent these things, for they are heavier
Than all thy woes can stir. Therefore betake thee
To nothing but despair. A thousand knees
Ten thousand years together, naked, fasting
Upon a barren mountain, and still winter
In storm perpetual, could not move the gods
To look that way thou wert.
What does this mean coming from a feminist standpoint? Hermione and Paulina are women who are oppressed despite their truthfulness, (Hermione by death and Paulina by the Lord) who are eventually recognized as honorable and steadfast. Shakespeare undoubtedly wrote many strong female characters that exhibit feminist qualities, but this is an example of plot that supports women in general as being true, constant, and loyal.
