Final answer:
Casca interprets the strange occurrences as omens and signs of impending doom, reflecting a belief in the supernatural influencing natural events.
Step-by-step explanation:
The student is asking about the character Casca's perspective on bizarre happenings within a literary context. Casca believes these strange occurrences to be omens and signs of impending doom. This belief is founded on the idea that when natural explanations fail to account for certain phenomena, what remains may be attributed to supernatural or spiritual causes. In literature, such events often serve as narrative devices to foreshadow significant future events within the story and to instill a sense of foreboding in both characters and readers.
For instance, multiple signs and omens prior to pivotal events are a common theme in tragedies like those written by Sophocles, where characters might interpret natural incidents as portentous. They often view such signs as orchestrated by fate or the gods, hinting at the destiny of the characters or the outcomes of the plot. This tendency to see the hand of the supernatural in natural phenomena reflects the characters' beliefs and may affect their actions within the narrative.
