Teacher looks for: Recognition of the story’s frame narrative structure and explanation of its purpose in building tension and credibility.

Frame Narrative Breakdown

The Call of Cthulhu uses a frame narrator, a man who inherits documents from his deceased grand-uncle. These documents include three separate accounts of Cthulhu-related events from different parts of the world. Use this structure to trace the narrator’s growing realization of Cthulhu’s existence. List one question the narrator asks at each stage of his investigation.

Core Theme of Cosmic Horror

Cosmic horror focuses on humanity’s powerlessness against unknowable, ancient forces beyond our control. The Call of Cthulhu emphasizes this by showing that even a global cult can only temporarily rouse Cthulhu, and humanity has no defense against him. Pick one moment from the story that practical illustrates this theme and write a 2-sentence analysis. Use this before class to contribute to discussion.

Cult of Cthulhu Overview

The cult of Cthulhu spans multiple continents and cultures, with members who worship the creature as a god. They believe his awakening will bring about a new era of chaos and power for his followers. Map the cult’s presence across three different regions using the story’s details. Highlight one similarity in their worship practices across all regions.

Narrative Structure Purpose

The story’s fragmented structure makes Cthulhu feel more credible and threatening. By using three separate, independent accounts, Lovecraft suggests the creature’s influence is widespread and well-hidden from mainstream society. Explain how this structure differs from a traditional linear narrative in a 3-sentence response. Use this before essay draft to strengthen your thesis about structure.

Unresolved Ending Explanation

The story ends without a clear resolution, as the frame narrator continues his investigation without finding a way to stop Cthulhu. This ending reinforces the theme of cosmic horror, as it suggests humanity can only observe, not fight, these ancient forces. Write one possible alternative ending and explain how it would change the story’s core theme.

Modern Relevance of the Story

The Call of Cthulhu’s focus on human insignificance resonates with modern discussions of space exploration, climate change, and humanity’s place in the universe.
