"Invisible Cities- Trading Cities 3"

Trading Cities is the story which tells about the city of Eutropia, the capital of a specific territory. The traveler sees Eutropia in different ways,essentially its size which is partially unequal. Additionally, It appears like a rolling plateau. The city consists of several cities that are waiting to be discovered by other inhabitants, therefore to start a new life there. However, the idea behind the story is that it reflects the rotation effect by which people are used with , but are not aware in general. Furthermore, the rotation effect in a way indicates the habits of people ,and how they change places continually. Another variant of rotation effect is partly illustrating the life cycle , where Calvino succeeded to generalize it as ongoing process.
