Pandora's box was a box made by the Greek Gods. Now thing is Pandora was also made by the gods, Athena made her extremely curios, then they brought her to earth. The Gods made Pandora to marry Prometheus's brother. Well she did marry him. Then as the Gods had planed they mailed her a box. Being that it was addressed to Pandora her husband (i cant remember his name) couldn't reject it. With the box they left a note that said "Don't open the small box" so, for a while she obeyed but then she grew more curious and eventually opened it in the box there was evil spirits but Zeus had pity for humans and also put the spirit of HOPE.
The theme of Pandora's Box is that curiosity can be a good thing but it can also be dangerous or curiosity killed the cat
