Kora

In Michelle Belanger's The Dictionary of Demons, Expanded & Revised (2021), Kore is listed:

In the Mathers edition of the Sacred Magic of Abramelin the Mage, Kore is identified as one of the principal spirits ruling a number of lesser demons.  In this text, Kore is often paired with the demon Magoth.  Another one of the eight infernal sub-princes thought to serve directly deneath the fiends Satan, Lucifer, Leviathan and Belial.  The joint hierarchy of Magoth and Kore is unique to the Mathers version of the Abramelin material.  In all other versions, this collection of demons is said to be ruled over by Magoth alone. 

Kore is another name for the Greek goddess Persephone, consort of Hades.  Hades was the Greek lord of the Underworld, and Persephone was his unwilling bride.  Because of their associations with the Underworld, these ancient dieties were sometimes integrated into demonology of the Middle Ages and Renaissance.  Notably, Charles Berbiguier identifies Persephoner as a queen of Hell, and ther stratus as an infernal ruler is repeated in Collin de Plancy's Dictionnaire Infernal.  Of course, to the ancient Greeks there was nothing infernal about this goddess.  Connected with the rites of the Eleusinian Musteries, she was a powerful and respected deity in the ancient world.  The Roman version of this Goddess was married to Pluto.  See also BELIAL, LEVIATHAN, LUCIFER, MAGOTH, MATHERS, PLUTO, SATAN.
