Saint and King, Louis IX of France represented the Holy Trinity in the 13th century with the Fleur de lis, the three petals representing each one of the persons in one the flower itself.
Representing the Holy Trinity in sacred art has always been an elevated and arduous task. How to represent such a mysterious principle so complex in our faith in an abstract way?
Artists have made remarkable efforts to present the Holy Trinity in a "visible" way to the Christian faithful through symbols.
The Trinity shield, is an ancient symbol, believed to have first appeared in the 12th century, that shows each Person of the Trinity is fully God, but, at the same time, the three are different persons from each other. Throughout history, it has been widely used as a remarkably effective catechesis tool.
