Symbols are what you want them to be. During the 18th century and prior, when it was rare for the masses to be literate, symbols were used to convey meanings- and few of the meanings were 'occult' (hidden). In some cases, they were used by occultists and the like, but more often than not, they predated the occultic use. The pentagram, for example, is commonly seen as an occultic symbol, but is also used as a symbol of time (8 year cycle), spring, the direction East, etc..
Imagine a time when few were literate, yet messages had to be passed.
“Imagine a time when few were literate. . .”
Right now, of course. I like your pentagram symbol list, haven’t seen that before.
And look at some the common symbols used today, an elephant for GOP and an ass for the Democrats. They convey perfect descriptions.
