The classic fleur de lis — a stylized depiction of an iris — has been in use for centuries. The emblem, literally translated from French as "lily flower", has had many incarnations from a symbol of royalty, to religious purity, to imposing security. This time-worn design continues to be renewed in our modern age with a plethora of beautiful wallpaper options.
In the above images we can see that the classic three-pronged shape of the fleur de lis can be pulled into many directions, or composed of pieces in different colors and line weights. And if the thousands of years of continuous usage haven't convinced you to commit, you can even find the fleur de lis on temporary vinyl papers to bring a little sense of history into your own space.
