Most people know that a wedding ring is symbolic of the bond of love and commitment between two
people. But not everyone knows about the history behind this small yet powerful symbol. The history of
the wedding ring goes back not just hundreds but thousands of years. No other currently practiced wedding
tradition has been around as long.
The Egyptians were the first recorded civilization to use the wedding ring. In Egyptian hieroglyphics
(象形文字), a circle represented eternity because there's no beginning and no end. Once a woman accepted
the ring she became the "property" of the person who gave it to her and she was in a sense "his". The first
wedding ring could have been made of braided grass or hay (which would have been changed often), ivory,
bone, or leather. Eventually, metal was used, but the first wedding bands were in the completely natural state
and rough. However, the wedding rings always expressed the same eternal and lasting love.
The Egyptians wore the wedding ring on the left hand because it was believed that a vein (静脉) in the
left hand went straight to the heart. This tradition is still commonly practiced today in most parts of the world
largely for practical purposes(most people are right handed). It is worn on the fourth finger of the left hand.
But there are some countries and groups which do not follow this tradition. In the Jewish faith, the wedding
ring is put on the index finger. Roman Catholics traditionally wore their wedding band on the right hand, and
in many countries and regions in Europe some people still follow this tradition.
It is interesting to note that in the long history of the wedding ring, it is only in the last century that men
began to wear them. However, now both men and women show their love and commitment by exchanging
rings on their wedding day.
Once you begin shopping for rings you may be amazed by the choices that await you. There are several
different types of metals: traditional gold, white gold, platinum, and titanium. You can have an inscription put
on the inside of the band if you like. Some people are even choosing a tattoo band. The styles vary from a
simple yet elegant band to an elaborate (精巧的) ring covered with jewels. If you do not buy the wedding and
engagement rings as a set, you will want to be sure the styles can match perfectly. Choose carefully because
this choice will need to stand the test of eternity.
