The ancient Greeks relied on help from non-Greek mercenaries when it came to fighting their enemies, suggests an analysis of bodies in 2500-year-old mass graves.
The western Mediterranean witnessed several conflicts between about 2600 and 2300 years ago as a number of Greek-led city-states – including Syracuse on the island of Sicily – fought against the Carthaginians, whose base of power lay in what is now Tunisia. The Sicilian wars were documented by contemporary writers, including Herodotus in his book The Histories. But given that Herodotus was Greek, it is possible that his accounts of the conflicts may have been biased to paint the Greek fighters in a favourable light.
