Wrong most of this symbology wasn't even thought about until the Shrine came into existance. Which was much later then the 1700"s. Go to www.masonicinfo.com and you will find out anything you wish within reason.
The elements that compose the symbols have been around a very long time, like the crescant moon and scimitar representing various aspects of Islam.
All I am saying is that there is nothing *sinister* about the use of the cresent as a symbol. It does not mean that the Freemasons have any ties to Islamic societies, though there may have been some at one time.
