What has an effigy of a knight Templar got to do with modern day bankers? You are asking.
Well once upon a time there was a group of knights, yes the ones that became known as the knights Templar. They weren't very wealthy. In fact they often had to share a horse, and they wore funny tin helmets. However, they were very good at fund raising and securing large donations from those who wanted a good place in heaven.
After about 100 years they built a lovely stone temple (known as the inner temple) in London, where 10 effigies now lay. By the 14th century these knights had become so wealthy they were in control of most of the money.
Now bankers take note of what happened next. People were rather unhappy with this state of affairs especially as many were struggling. The knights were charged with heresy, blasphemy and sodomy and chucked into the Tower of London.
What happened to all the assets? The lawyers took it all.
