sequences in the past architectures

Even though we figure out most of the information about sequences in nowadays research, ancients use them as well. One usage of sequence is back to Egyptian Pyramids. Also, in some countries with a long history of architecture it was common to use sequence and geometry in their buildings and constructions. Persian architecture is famous for using ambulant geometry symbols like squares and triangles in a specific sequence. Moreover, it was also common to use sequences in symbols in tiling and mirrors by architects, especially in palaces and courts of the kings. In short sequences could be really helpful in architecture because it gives tidiness and orderliness to the structures so it's understandable that architects use a lot of them in their works!
