The symbolism behind the scarlet letter A changes throughout this novel. Though initially this letter A symbolizes the sin of adultery, Hester Prynne alters its meaning through her hard work and charity. Some people begin to suggest that the A stands for "able," since Hester is such a capable woman. Others begin to recognize that the scarlet letter has begun to achieve holiness, righteousness. It has "the effect of the cross on a nun’s bosom. It imparted to the wearer a kind of sacredness, which enabled her to walk securely amid all peril. Had she fallen among thieves, it would have kept her safe" (13.5). Many years later, when Hester returns and voluntarily takes up the scarlet letter again, it has become, for her and others, a symbol of grace.
Hester sews this letter herself while in prison, and the result is breathtaking:
On the breast of her gown, in fine red cloth surrounded with an elaborate embroidery and fantastic flourishes of gold thread, appeared the letter ‘A.’ It was so artistically done, and with so much fertility and gorgeous luxuriance of fancy, that it had all the effect of a last and fitting decoration to the apparel which she wore; and which was of a splendor in accordance with the taste of the age, but greatly beyond what was allowed by the sumptuary regulations of the colony. (2.10)
By embroidering the “A” so finely and ornately, Hester takes control of her own punishment. She owns it. Though the letter causes Hester to live a lonely life of banishment and ostracization, it seems almost immediately to become a symbol for something far nobler than “adultery.” The letter showcases her talent and artistry – skills that allow her to make a living as a single parent in Puritan Boston. As such, it represents her strength and independence. Such qualities set her apart from every other woman around her. Wearing the letter cuts her off from society, but it also frees her in many ways. She is able to observe the cold and strict ways of Puritan society from the perspective of an outsider.
