Pentagram Within Hexagram

There were times when both pentagram and hexagram were named Star of David, or Solomon's seal, but to add confusion here is a strange phenomenon where the one is surrounded by the other. The coin is from Morocco its value is 100 francs and it was issued on 1953.

Astronaut Ilan Ramon

Astronaut Ilan Ramon felt as a representative of the Jewish people:

·        He took into space a mezuzah with a Star of David, a microfiche of the Bible and a tiny Torah scroll.

·        He used to carry a Star of David on his shirtsleeve.

·        He was not religious but he decided to eat kosher food in space.

 

Rabbi Shraga Simmons wrote:

After the tragedy, I saw an editorial cartoon that depicted a father and son, gazing at the night sky. Seven stars dotted the heavens -- six regular stars, and one Star of David. As the father placed his arm around the boy's shoulder, he pointed to the Star of David and explained: "That one is Ilan Ramon.

Solomon's Seal Legend

Joseph Jacobs and M. Seligsohn wrote in the Jewish Encyclopedia:

The legend that Solomon possessed a seal ring on which the name of God was engraved and by means of which he controlled the demons... is especially developed by Arabic writers, who declare that the ring... was partly brass and partly iron. With the brass part of the ring Solomon signed his written commands to the good genii, and with the iron part he signed his commands to the evil genii, or devils...The legend of a magic ring by means of which the possessor could exorcise demons was current in the first century, as is shown by Josephus' statement ("Ant." viii. 2) that one Eleazar exorcised demons in the presence of Vespasian by means of a ring, using incantations composed by Solomon.
The Arabs afterward gave the name of "Solomon's seal" to the six-pointed star-like figure (see Magen, Dawid) engraved on the bottom of their drinking-cups.
