In the prehistoric age, our ancestors drove out animals from the caves to settle inside and get protections from dangerous conditions. They struggled for a place to survive and began to create human beings’ civilizations. The unclosed face of a cave is the weak point to be attacked by their enemies-the beasts. Nowadays, we call it façade in the concept of architecture. It is the walls with windows and doors that keep us from outside while at the same time, enable us to communicate with environments. Though not as the ancient time when we needed to worry about our life safety all the time, we have begun to worry about our privacies of living conditions and the simple and forceful attacks in the past have transformed to complicated and soft ones which are hard to be prevented with merely closing doors.
Roof of houses protects us from bad weather conditions equally as umbrella-like coverages functioned in the past. The modern concept of the roof is the fifth façade that can be seen in a bird view. What we need seems simple, just with some shelters like roofs and facilities like staircases, it could be called an architecture. But as it is built for human beings instead of animals, just a satisfaction for the basic living conditions is not enough. In the architectural history, we have been long discussing how to live more comfortably, not only for senses of the human body, our awareness, interactions between social individuals, all need deep reflections.
Architecture is also intended for evolutions of our culture and civilizations. Cave paintings dated to 40,000 years ago represented similar subjects of animals to arouse the hunting magic. However, for ceremonial purpose, these caves are not easily accessible. In contemporary age, art has been understood as conception so without artists, there is no art. Modern artists do not have to blow pigment on a hand held to the wall for being forever remembered. In the future, hidden caves, maybe not even any kind of architecture will be needed for arts’ recordings. In the picture-turn age, Artworks, together with the artists’ faces, would be recorded and broadcast to all over the world through the Internet.
