In Margaret Atwood's "The Robber Bride," the quote "Art is long and life is brief" speaks to the enduring nature of artistic creations compared to the fleeting experience of human life. This contrast highlights the lasting impact art can have, outlasting the individuals who create it. The phrase also underscores a universal truth about mortality, reminding us that while we may be limited in time, the expressions of our creativity can transcend that limitation.

Atwood's exploration of this theme resonates deeply in the narrative, as characters grapple with their own mortality and the legacies they leave behind. Their experiences reflect the tension between the ephemeral nature of existence and the potential for art to provide meaning and permanence. Ultimately, the quote encapsulates a profound reflection on how art can serve as a form of immortality, preserving thoughts and emotions long after life has ended.
