The Changing Demographics of a Syrian Refugee

In this clip, Professor Casagranda states that Greek fire was invented by a Syrian refugee.  There is no further context to that.  Well, everyone knows what a Syrian refugee is, right?  We just had thousands upon thousands of them flee the Syrian Civil War and flood into Europe.  They are mostly Arabic Muslims.  Anyone watching this clip will mistakenly conclude the same of the refugee who invented Greek fire.  Why would you not?  Unless you actually know history, like Professor Casagranda.  A 7th century Syrian refugee is quite different from a 21st century one.  In fact, Callinicus of Heliopolis was a Greek-speaking Jewish architect who fled the Muslim conquests of that Christian nation.  Huh.  I'm sure that omission was unintentional.
