八卦镜
八卦镜也叫太极八卦镜：在我国一直被称为风水吉祥物。据传，在距今七千年前的上古时代，伏羲氏观物取象，始作八卦。"以通神明之德，以类万物之情。"《易系 辞传》说："易有太极，是生两仪，两仪生四象，四象生八卦。"太极就是一，就是道，是元气浑然之象，是造分天地的根源。太极动而生阳，静而生阴，一阴一阳 就是两仪。而两仪又生一阴一阳既是四象(少阳、老阳、少阴、老阴)。四象是天地阴阳在自然界中的变化，也代表春夏秋冬四时。而四象再各生阴阳，就生成了八 卦。八卦用以代表天、地、风、雷、水、火、山、泽，并表示健、顺、动、人、陷、丽、止、说等。而镜自古以来就是震慑邪魅的吉祥之物。传说"帝会王母于王 屋，铸镜十二，随月用之，此镜之始也。"古镜用铜铸成，在战国时期就开始盛行。太极八卦图，以同圆内的圆心为界，画出相等的两个阴阳表示万物相互关系。阴 鱼用黑色，阳鱼用白色，这是白天与黑夜的表示法。阳鱼的头部有个阴眼，阴鱼的头部有个阳眼，表示万物都在相互转化，互相渗透，阴中有阳，阳中有阴，阴阳相 合，相生相克，即现代哲学中和矛盾对立统一规律表示法。
