Poetic justice refers to the literary device wherein virtue is definitely rewarded and the vice is ultimately punished. Personally, the use of poetic justice as a literary device in the story of Arachne is effective because it helps in effectively relaying and delivering the message and the moral lesson of the story. The punishment shown in the story absolutely adds an impact of the events  in the story that highlights the value of humility and gratitude necessary to be possessed by an individual.
