I think you can get rid of the word mythology, another joke. How can you discuss about something you don't know and who would you be to discuss a story someone tells you ?
Myths were used long before writing was developped. They were using archetypes, making time irrelevant. They were not chronicles, the roman tradition, trying to pinpoint a particular individual, where it depends on who writes for whom and the portrait is inevitably squewed. Also, the lives of emperors are useless.
Three main sources remain for our mythic tradition : Orpheys, Omer and Esiod. And if you think those are birth name, think again (roughly "See the light in the head", "See the sea" and "Past food").
Esiod Theogony, or angle of thinking, relates primordial myths. Most of the stories are embedded in the names and use dualities.
Centering on Iapetos (they say digger, but more the fallen, ie Man). A duality you will find is in a couple, Iapetos is with Klyménè, without entering into details, prototypical wife and mother. She comes with the epithet kallisphyron, quite directly meaning nice to get intimate with... (and not neat-ankled, joking translators)
The story becomes interesting with their four sons.
The name Menoitios was derived derives from the Greek words menos meaning variously might, force, spirit, passion, batterage, and oitos meaning ill-fated or doomed. Hesiod also describes him as hybristes, a violent, overbearing and insolent man. Menoitios and his brothers, the sons of Iapetos, were all depicted with extreme human foibles : Prometheus was overly crafty, Epimetheus a fool, and Atlas exceedingly daring.

Pro-metheys cannot be properly apprehended without his obvious dual Epi-metheys. To make the story short:
The overly prudent Prometheys marries his "mother", one son (nice couple)
The superficial Epimetheys marries Pan-dora (she wants all the presents in the world), one daughter (fire or fiery)
The obnoxious Menoitios aggresses Artemis, blasted
The enduring Atlas or more accurately Atlanta ends up having the burden of descendance upon his shoulder with 50 offsprings
Hum! four to represent a generation
There is a city called Atlanta. And this interesting line on the globe Just that by using Google Earth, the line passes 30km south of Stonehenge and not in London, but more interestingly about midway between Paris and London (Troy again ?)...

To finish, another way to assess a myth is by comparing it to another myth (dualities all the way). So, you can assume Agamemnon is Prometheys and Menelaos Epimetheys. Klyteimnestra (listening to pretenders) is Agamemnon's downfall and Élénè releases 10 years of disasters by following her whims... (Priam and Alexandros/Paris as Atlanta and Menoitios)
