It’s not the color of Valentine’s Day... any color will do, as long as it’s a heart. As the celebration of love approaches, consider the origins of the symbol of love.
The most basic geometric shapes are circles, squares, rectangles, and triangles. These combine to create hexagons, polygons, diamonds, and other classic forms. As cultures and religions evolved, new shapes emerged: crescent moons, yin yang, crosses, teardrops, and hearts – for example. Some are easy analyze; others, like the heart, not so easy.
The origin of the heart symbol becomes more complex because the heart is found in many different cultures: Hindu, Buddhist, Celtic, Christian, Hebrew, Muslim, Aztec, and Taoist.
When we turn to geometry, we find no logic. The heart is not a derivative shape, as would be the case with the cross.
