In the drawing above the Sea
Goddess Thetis submerges her son Achilles in water from the Styx, to make him
invulnerable. Unfortunately the water doesn’t touch the heel, where she holds
him and his heel becomes his most vulnerable part.
When Achilles was a baby, it was
foretold that he would die young. To prevent that his mother Thetis took
Achilles to the River Styx, which was supposed to offer powers of
invulnerability, and dipped his body into the water.
Achilles grew up to be a man of
war who survived many great battles. One day, a poisonous arrow shot at him was
lodged in his heel, killing him shortly afterwards.
