In Greek mythology, it is said that people were originally round. But because of offending Zeus, Zeus split the man in half. From then on, the primitive half is always looking for the other half that was once connected with itself. Therefore, people are all incomplete individuals split into two halves. They spend their whole life looking for the other half, but they may not be able to find it.

According to this mythology, the semicircles are compared to human, all changes are based on encounters between people.

Can we meet with our half one?
