Sometimes mythology doesnt follow a set time-line. For example, the Greeks told stories of Heracles and the Romans told stories of Hercules. The same person, but different mythology. At the Trojan War, both sides (Greeks and Romans) tell stories of their own heroes and while they may have similar events, they may not all be the same
