Hexagram as a Homonym

One of the factors that complicate researching the Star of David symbol is that the Hexagram is the name of a few different things:

A. The six-pointed star (Star of David)
B. The Unicursal hexagram (drawn unicursally)

C. The name of each of the 64 yin-yang diagrams in the Chinese Book of Changes (I Ching)

D. The name of a large silver coin issued by 7th century Byzantine Emperors (Heraclius, Constans II, and Constantine IV)

E. The name of a six-pointed star made from 6 radiuses starting from the same point, and not from two triangles.
