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.

In the Wikipedia entry for Fractal they say

a fractal is a rough or fragmented geometric shape that can be subdivided in parts, each of which is (at least approximately) a reduced-size copy of the whole.

Song of Solomon 2:16 "My Beloved is Mine and I am His" . To me that is really what love is about.

Arab House near the Temple Mount

Picture of a Hexagram on an Arab House near the Temple Mount is courtesy of "keithwills" who published it on Flickr and wrote in the caption:

The Arabs will tell you that they were the first to have posession of the temple yet here we see the star of David on one of their buildings. They built most of their area of the temple from rubble from the old temple.

It seems to me that these Stars of David, about a meter below the roof of this building, are not that old but keithwills surely chalenges the experts to explain where did these emblems come from...

Church in Brazil

Fools of Prophecy

A Magen David surrounded by pomegranates on the announcement about the show of the Israeli rock band called Fools Of The Prophecy. I guess the Magen  David is meant to emphasize the word Prophecy since the band is dealing with Judaism and humor.
