What is the origin of the saying happy the corpse the rain falls on?

The saying "happy the corpse the rain falls on" originates from a line in the poem "The Ballad of Reading Gaol" by Oscar Wilde, written in 1898. It reflects a sense of resignation and acceptance of fate, suggesting that those who have passed away are free from the struggles and suffering of life. The imagery of rain falling on a corpse conveys a bittersweet notion of peace in death, contrasting with the burdens of the living. Wilde's use of this phrase captures the melancholic beauty of mortality and the release it brings.
