With this ring, I thee .....
The oldest recorded exchange of wedding rings comes from Egypt about 4800 years ago. Made of reeds that grew alongside the Nile, they were braided into rings as a decorative ornament for the women to wear. The circle symbolized eternity, and the hole a gateway leading to events both known and unknown. Since reeds didn't last long, soon other materials were used, such as leather, bone, ivory. The greater the worth of the material the greater the love, or the better show of wealth.
Around the year 860, Christians started using rings. Some say the ring is placed on the fourth finger of the left hand because of the vein that goes directly from there to the heart. Another theory is when the priest was reciting the binding, he would say, "in the name of the Father, the Son and the Holy Spirit". As he said this he would take the ring and touch the thumb, the index finger and the middle finger; then while saying "amen" he would place the ring on the ring finger, which sealed the marriage.
