Long ago, the only water that was available was in places the Poseidon wanted them to be. Poseidon, who was the god of water, liked it this way. He got to rule over all the waters with little to no work. The people who lived in deserts, however, looked at Poseidon with hatred for not giving them water.
My family and I need it to survive!
Please give us water!
He removed the waters from the desert out of anger. This was after a break up with another god named Aphrodite. They separated by one of their rivers. He decided to punish the desert's people for living in the area where he lost his love, Aphrodite.
Aphrodite, the god of love, often watched the people of the desert from the tops of sand dunes. She pitied them as they begged Poseidon for water but received no answer.
Aphrodite felt terrible for causing Poseidon to put them in that state. She thought and thought about what to do. To make up for it she blessed the land with love. She made it that all whom shall love one another there will have flourishing love.
Eventually, Poseidon grew angry at Aphrodite for casting that spell. He envied the desert people's glee. He decided to change things back to his own way. He summoned one of his sea monsters, changed it to make it look like a human, and sent it into the desert. He named his new disguise Ptolemy.
One day, an unfortunate, beautiful, young girl named Ariadne locked eyes with Ptolemy. She instantly fell in love with him, but (because of Poseidon's curse on him) he would never love her back.
Thereafter, Ariadne spent almost all day and all night watching Ptolemy from their front doorstep. No matter what the weather. She was just trying to get Ptolemy to notice her... but he never did.
