Duma

Duma(h) or Douma - The angel of silence and of the stillness of death.  Duma is also the tutelary angel of Egypt, prince of Hell, and angel of vindication.  The Zohar speaks of him as having "tens of thousands of angels of destruction" under him, and as being "chief of demons in Gehinnom [i.e. Hell] with 12,000 myriads of attendants, all charged with the punishment of the souls of sinners."  [Rf. Muller, History of Jewish Mysticism.]  In the Babylonian legend of the descent of Ishtar into Hades, Duma shows up as the guardian of the 14th gate. [Rf. Forlong, Encyclopedia of Religions.]  Duma is a popular figure in Yiddish folklore. I.B. Singer's Short Friday (1964), a collection of stories, mentions Duma(h) as a "thousand-eyed angel of death, armed with a fiery rod or flaming sword."  (a)
