“Fear no more the heat o’ the sun / Nor the furious winter’s rages” (9) (repeated)

This repeated line comes from Shakespeare’s Cymbeline, Act IV, Scene 2 in which the characters Arviragus and Guiderius assume that the tragedy’s heroine – Imogen – is dead, and they process and eventually accept that this death is inevitable. This fits well with one of the major themes running through Mrs. Dalloway – everyone will die in the end, whether they want to or not. It is fitting that Clarissa thinks of these lines while she contemplates if her efforts are worthwhile: will they really matter when she is gone forever?
