From the experts:
Eris was the goddess of strife and discord, turned fairy tale and then popular culture figure Maleficent in Sleeping Beauty. Ironic, as her name sounds so much like that of Eros, the god of love. There is also a planet named Eris, discovered in 2005 and sometimes called the tenth planet. Though not on the U.S. Top 1000 except for a brief appearance a century ago, Eris was given to 78 little girls in 2016 and may rise along with the fashion for mythological names.
