About Symmetry and PatternRug GalleryAbout Oriental CarpetsEducational ResourcesAbout This Web Site
ORIENTAL CARPETS have long been appreciated for their beauty. That beauty isachieved through the choice of colors and designs, as well as by themanipulation of designs and colorsto form pleasing patterns. Patterns in Oriental carpets are never quite what youexpect - a surprise here, a flourish there, a change of color,the flip or rotation of a design where you might not predict it. The moreyou look, the more variations you will find. How can we explain this phenomenon? Is it the result ofhuman choice, or human error? The study of symmetry offers one approach to analyzing patterns inOriental carpets. Through symmetry analysis wemay identify areas of pattern that exhibit expected repetitions,and areas that vary from that expectation.© 1997-2005 TheTextile Museum & The Math Forum @ DrexelViewers' Comments || Contact Us
