Homer's Iliad is full of brief references to named individuals, describing for example how those individuals kill or are killed in battle. Many of these individuals seem to appear only in these particular references, and are never referred to again in other, extant, ancient Greek literature (at least not in literature that is well known). The tendency is to skip over these names and forget about them. My guess is that these are not invented, fictional characters but actual people who lived somewhere in the ancient Greek world, possibly during a wide variety of different time periods. Has any research been published that seeks to explain the origins of this wide-ranging collection of little-known characters?
