Eris was not invited to Peleus and Thetis's wedding and got furious!
The Decision ...
I promise supreme wisdom.
I promise wealth and power!
I'll give you a wife as beautiful as me!!
Eris then wanted revenge and threw a golden apple into the wedding with "The fairest" written on it.
The Perfect Wife...
This ended up with Hera, Athene and Aphrodite three of the goddesses fighting, so, they asked the Gods who the fairest was but they didn't reply.
I love you!!
Lets runaway, I have a boat!
Athene, Aphrodite, and Hera then went down to Troy to find a man named Paris and he was bribed by all the three goddesses and had to make a decision.
I chose Aphrodite!
Since Paris had chosen Aphrodite he had later on heard of a beautiful woman in Greece called Helen who was getting married to a man called King Menelaus Sparta. Paris travelled to Greece and found Helen.
What brings you here?
Paris and Helen fell madly in love and Helen left Menelaus and they sailed away together.
