Janus was one of the many admirers of the nymph, Cardea. Cardea had been known for leading her unwanted followers into caves and then leaving them in there. When Janus followed her into the cave and she turned to leave him, he saw her with his head facing the back, and he caught her. Cardea later became the goddess of hinges, and a companion of Janus. She helped him so much that she became the “Lady Protectress” of doorways. She was very sacred to him, she even got a holiday made for them.
Janus also set right many injustices. Once when Romulus and his people captured a Sabine woman, Janus caused a hot spring to erupt and bury the kidnappers alive in ash and lava, saving the woman. He then help persuade the Romans and Sabines to unite and create their own joined community. Janus brought peace as he could to the troubled people in the empire, but even he could not keep them from war, especially with his two sided nature.
