Porphyria's Lover is a poem written by Robert Browning and published in 1836. It tells the story of an unnamed man who kills his lover, Porphyria, out of love and then watches her corpse as he reminisces about their relationship. The poem has been widely studied for its complex themes of power dynamics between men and women, sexuality, madness, morality, religion and gender roles.

The language used in this poem reflects the emotional turmoil that exists within it. The narrator describes himself as feeling "too weak" to resist his own desires when he murders Porphyria, which suggests a lack of control over his emotions but also speaks to how intense they are, while at other times he appears almost serenely detached from what is happening around him, such as when describing the storm raging outside during the murder scene: "And yet God hath not said a word." This juxtaposition creates an atmosphere that captures the confusion and complexity inherent in human relationships.

In terms of literary analysis, there have been numerous interpretations proposed for this work, ranging from feminist readings focusing on male domination over female autonomy to psychoanalytic theories concerning repression or insanity, amongst others. Despite these various views, however, one thing remains clear – Porphyria's Lover is undoubtedly one of Browning's most famous works due to its intricate exploration of topics such as desire, violence, and passion, which remain relevant today, making it an enduring classic piece within literature circles worldwide.
