Literally: “of Niobe”
The story of the word
Heinrich Rose named it in 1844 for Niobe, because he had found the metal entangled with tantalum and wanted the family relation recorded: in myth she is Tantalus's daughter. American chemists went on calling it columbium for another century, until the name was settled internationally in 1949. Niobe wept for her fourteen slaughtered children until she turned to stone, and guides on Mount Sipylus still point out the weeping rock.
