What sort of mythology really lies in Pandora's Box?

Pandora,s box is a greek myth about curiosity.
This myth is retold several different ways.
The greek gods played a nasty trick on the human race.
They explain the presence of evil in the world with this myth.
Other stories are similar but the greek/roman gods are the meanest of the pantheons.

One of the many interpretations of it is: To open a Pandora's box means to unwittingly unleash chaos on yourself and those around you.

This is where the mythology comes in... the basic lesson that is taught is to not be too curious because it is not wise to mess with the things that you do not understand. Much of this is still VERY true today... I hope this is another answer to your question.....

The story goes like a law given to eve to forbids her to eat a fruit from a forbidden tree.

In Greek mythology, Pandora was the first woman on earth. Zeus ordered Hephaestus, the god of craftsmanship, to create her and he did, using water and earth. The gods endowed her with many talents; Aphrodite gave her beauty, Apollo music, Hermes persuasion, and so forth. Hence her name: Pandora, "all-gifted".

Pandora

When Prometheus stole fire from heaven, Zeus took vengeance by presenting Pandora to Epimetheus, Prometheus' brother. With her, Pandora had a jar which she was not to open under any circumstance. Impelled by her natural curiosity, Pandora opened the jar, and all evil contained escaped and spread over the earth. She hastened to close the lid, but the whole contents of the jar had escaped, except for one thing which lay at the bottom, and that was Hope.
