Heron appears in Egyptian hieroglyphs as a manifestation of the creator god of Heliopolis. Five hundred years before Christ was born, Herodotos visited Egypt and decided that Heron was in fact Phoenix. The concept of Phoenix rising from the ashes is alive and well in most world mythologies and all depict their Phoenix as being what might be a stylized Heron. The most famous person named Heron in history was Heron of Alexandria, a Greek mathematician who lived in Alexandria, Egypt during the first century of the Christian era. Among his contributions was the formula for the area of a triangle.
