What does the word omen mean in book Iliad?

The word "omen" in the book Iliad refers to a sign or event that is believed to foretell the future. Specifically, it refers to the appearance of a bird or other animal that is considered to be a messenger from the gods. In the Iliad, omens are often used to foreshadow events that will happen later in the story.

For example, in Book Two of the Iliad, a snake appears in Zeus's temple, which is taken as an omen that the Greeks will be victorious in their war against the Trojans. In Book Twelve, an eagle is seen carrying a serpent, which is interpreted as a sign of trouble for the Trojans.

Omens are an important part of the Iliad and help to create a sense of suspense and foreboding. They also add a layer of complexity to the story, as they suggest that there is a higher power at work in the world of the gods and humans.
