Final answer:
In the context of 'Prometheus: The Friend of Man,' the word 'vex' likely means to cause annoyance or distress. The usage in the story suggests that Prometheus's actions frustrate or worry the gods, a definition that is supported by checking a dictionary.
Step-by-step explanation:
To determine the meaning of the word vex as used in Prometheus: The Friend of Man, context is essential. In literary contexts, vex often refers to causing annoyance or distress. For example, if Prometheus's actions are said to vex Zeus,
it means that Prometheus's actions are causing Zeus annoyance or irritation. One could surmise that since Prometheus is a friend of man and often acts against the will of the gods, he creates situations that disturb or complicate matters for them.
After formulating a preliminary definition, one should verify it by reviewing the actual usage in the text as well as consulting a dictionary. A dictionary would likely define vex as to make (someone) feel annoyed, frustrated, or worried, especially with trivial matters.
This definition aligns with the context in which the word is likely used in the story of Prometheus.
