On the topic of Lucifer:
Several years ago I was admitted into a mental ward and found an old magazine - IEEE Internet Computing from March - April 1997. The back cover had an interesting ad involving revolutionary technology. From the Wikipedia article on "Lucent"... "This same linguistic root also gives Lucifer, "the light bearer", who is also a character in Dante's epic poem Inferno." Apparently Lucent has been located at 666 Fifth Avenue.
If it wasn't for that magazine I found, there would be no publicly available record of their amazing ad. I am the person who uploaded it to Wikipedia which has since been replaced with an unreadable low resolution version. I also helped add the information about Lucifer to the Wikipedia article - though when I first found the magazine I didn't suspect there was any Satanic connection.
