Adolf Franz Karl Viktor Maria Loos was a modern architect in europia. His architectural theory was about ornamentation.He explored the idea that the progress of culture is associated with the deletion of ornamentation from everyday objects, and that it was therefore a crime to force craftsmen or builders to waste their time on ornamentation that served to hasten the time when an object would become obsolete . Loos’ stripped-down buildings influenced the minimal massing of modern architecture, and stirred controversy.He strongly believe that nobody cannot change human evolution. Periods are changing day by day and it cannot be stoped.In the past people are interested in ornamentation.They ornamented everything which is accesible from human such as their own bodies,ships,woods,barracks. However thr ornamentation is decreasing, even disappear. Therefore, many other arts become and process with decreasing ornamentation. Maybe, The lack of ornament represent power.When the ornamentation decrease, invented to power is focused on other things like music.
