More recently, the five-pointed star has been widely used as a symbol for Natural Man, its five branches suggesting two legs, two arms and a head. As such, it was known as the Drudenfuss (Druidical sign), or Celtic Star, in Europe. In its upside-down position, with one point at the bottom, it is seen as a magic sign of evil.
Many nations took to the pentagram, showing it in their flags. These include Egypt, China, Libya, North Korea, Syria and Yemen. It was also represented in the flag of the former Soviet Union, as the so-called Red Star. In the flag of the United States, each member-state is represented by a pentagram. Recently, the European Parliament chose a circle of 12 pentagrams as its symbol.
Intriguingly enough, these countries are also world leaders in astro-sciences and astro-techniques, as was ancient Babylon, empire of the Chaldeans.
