“Epiphany” is an artistical writing technique that James Joyce adopted in many of his works, from Dubliners to A Little Cloud. By an "epiphany", he meant a sudden spiritual manifestation, whether from some object, scene, event, or memorable phase of the mind. “Moment of importance”, as another significant skill in the stream-of-consciousness writing, can be found throughout Virginia Woolf's fictions, from Kew Gardens to The Mark on the Wall. Woolf used it to explore human beings’ spiritual world. There are mainly three similarities between Joyce’s Epiphany and Wooff’s Moment of importance.

In A Little Cloud, Chandler experiences various mental activities from his initial "psychological paralysis" to hope, to joy, to happiness, to disappointment, to disillusionment and till his final epiphany, which is a gradually accumulated process.Through all his mental experiences, Little Chandler finally accomplishes his epiphany with tears of remorse for his weakness and timidity. Similarly, Woolf’s “moment of importance” in The Mark on the Wall is also elaborately adopted to reflect the narrator’s mental experiences, which are fragmentary but structured as a spiral flowing stream of consciousness.

Little Chandler's final epiphany results from the setbacks he experiences in the external world, including the filthy picture of the paralyzed city Dublin, Gallaher’s sucess, scorn and insult, and his own sense of failure in work and family. In The Mark on the Wall, the moment of important is stimulated by the sight of the mark on the wall, which functions as an external stimulus to the narrator’s mental exploration.
