The story centers on the rage of the great warrior Achilles. But it includes many details of injuries and outcomes, and is thus the oldest record of Greek medicine. Here is a table of 146 recorded injuries for which both injury site and outcome are provided in the Iliad. Are some kinds of injuries more lethal than others?
