Often, in the Iliad, the poet will describe something – usually part of a battle – by a long, drawn-out simile. (For more details on the so-called "Homeric simile," see our section on "Writing Style.") In these similes, acts of warfare are typically compared either to peacetime human activities, such as handicrafts or tending sheep, or to elements of the natural world, such as waterfalls or lions.
Even though there is always some obvious connection between these two images, scholars have wondered if anything is going on at a deeper level. Are these scenes of peacetime and nature meant to contrast with the violence of war? Or are they to suggest that war is itself either a human activity like any other, or simply a part of nature? These questions are compounded by the famous Shield of Achilleus passage, which is usually interpreted as an image of the world as the Ancient Greeks understood it. This shield also depicts a mixture of human activities and nature, as well as peace and violence. In this way, what seem like poetic flourishes or a flight of descriptive fancy actually point to the philosophical heart of the poem.
