Hera suggested a competition. Whoever made mankind peaceful first should apologize to the other. Hera liked Poseidon and envied the mother of the Goddess. She knew water was the source of life and could make people peaceful again.
天后赫拉建议两人比赛，看谁能更让人类感受和平，谁输了谁就向对方道歉。赫拉偏爱波塞冬，又嫉妒正义女神的母亲，她知道水是生命的源泉，一定会让人类感到和平。

The arena was a square in heaven. When Poseidon distributed clear water, people felt comfortable and at ease with it. At this moment, the Goddess became a tree with red trunk, green leaves and golden olives. Everyone felt its peace and love. Poseidon smiled at Goddess and knew she had won.
比赛的地点设在天庭的广场，由海神先开始。只见波塞冬朝墙上一挥，裂缝中就流出了非常美的水，晶莹剔透，让人看了以后感到无限的清凉与舒适。这时候正义女神变成了一棵树，这棵树有着红褐色的树干，苍翠的绿叶以及金色的橄榄，任何人看了都感受到爱与和平。波塞冬朝女神微笑着，他知道女神的心愿终于实现了。

Poseidon and the Goddess restored their relationship. To commemorate the result, Zeus threw a balance on the sky and called it Libra.
人类认识到和平的重要，女神与波塞冬和好如初，宙斯为了纪念这样的结果，把随身带的秤往天上一抛，就有了今天的天秤座。
