Fish Jewelry History

Fish scales were used in primitive times because of their availablitity (byproducts of cleaning fish for eating) and beauty (shiny and at times colorful). The whole fish as a symbol originated in various cultures. The fish was worn as a symbol of fertility and birth in various pagan cultures, including the ancient Egyptians, Romans, Greeks, and Celts, as well as others). The ancient Polynesians wore fish hooks as jewelry to symbolize prosperity and health because, as island people, they derived those benefits from the ocean. This custom has been particularly popular among the Maoris of New Zealand and has been continued in the Hawaiian culture. The fish is popular in Christian jewelry. It was a secret symbol used by the ancient Christians in Roman times to identify each other. They consider fishing a symbol of missionary activity, but the pagan Romans did not detect it as such because it was also a pagan symbol.

Heart and Love

William Harvey demonstrated that the heart is a pump that drives the blood to circulate around the body, and that is what is scientifically known today. Emotions come from the brain. In ancient times and until the time of Harvey, the heart was thought to be the human organ from which emotions came. References to this concept are found in many documents, including the Egyptian Book of the Dead, the Hebrew Bible, the writings of the Greek philosopher, Aristotle and the Roman physician, Galen, and the Christian New Testament. Although scientifically we now know that the heart's function is to pump blood, symbolically we still associate the heart and its beautiful shape with love.
