St. George is also the patron saint of Ethiopia, although there isn't a cross contained within their flag.
One of the most famous invocations of St. George is in William Shakespeare's play Henry V:
"I see you stand like greyhounds in the slips,
Straining upon the start. The game's afoot;
Follow your spirit: and upon this charge,
Cry — God for Harry! England and Saint George!"
St. George (Sant Jordi) is also the patron saint of Catalonia.
Today is therefore a good time to remember Jordi Cuixart & Jordi Sànchez, two of the Catalan political prisoners held in Spanish jails.
