Though the saying that “eyes are the window to the soul” is quite familiar to us, this figure of speech has long existed in other forms.
Cicero (born in 106 BC) was quoted saying “Ut imago est animi voltus sic indices oculi” or that “The face is a picture of the mind while the eyes are its interpreter.” Around the same time, some popular Latin proverbs too held similar meanings: “Vultus est index animi” or “Oculus animi index”, which generally mean that the face is the index or measure of the mind.
The light of the body is the eye: if therefore thine eye be single [to the Glory of God], thy whole body shall be full of light.Matthew 6:22
Today, we would often hear the French saying “Les yeux sont le miroir de l’dme”, which means the eyes are the mirror of the soul.
These musings just go to show how powerful our “eyes” are that we’re able to “look into” them and see one’s “soul”. How true this is, however, still remains to be seen.
