This paper aims to read closely Becky Sharp`s character and its significance in relation to the total picture of the "Vanity Fair" as well as to Thackeray`s authorial intention. Although Thackeray subtitled Vanity Fair "A Novel Without Hero", most readers and critics agree that the unforgettable Becky Sharp is the heroine of the novel and plays the critical role in showing us the hypocrisy and vanity of the Victorian upper middle and high classes. Becky, in a sense classless because orphaned, is free to move between classes and is able to reach beyond her given social status by manipulating people`s vanity and self-interest. She struggles by witty, yet painful, strategies to obtain a suitable husband - one with wealth and a recognised position in society. Although traditionally she has been regarded only as an embodiment of evil and an example of sinful deceit and false virtue, we can admire her various artistic talents and social graces providing characters with great pleasure and joy even though for limited periods, especially if we separate virtue from chastity in evaluating her strengths. Language plays a vital role in her social success. Even though she is accomplished at piano and charade, the main tool of her social ascent is her witty talk Thackeray seriously doubted whether art and language could genuinely represent the true state of human life. If we view the nature and role of Becky from this point of view, we can infer that Thackeray staged Becky to show the false limitations of art and language in addition to his attempt to mirror the artifices of the upper Victorian society. Besides he seems to have attempted to satirize the equally narrow Victorian concept of "virtue".
