BIL.  m.  "The Lord."  A Himyaritic deity.  He may probably have been the Bel of the Chaldeans. (An Archaic Dictionary, Cooper, 1876).

BIL.  f.  "The waning moon."  In Scandinavian mythology, the sister of Hiuki (q.v.).  They were children of Widfinur.

... Mani was also accompanied by Hiuki, the waxing, and Bil, the waning moon, two children whom he had snatched from earth where a cruel father forced them to carry water all night.  Our ancestors fancied they saw these children, the original "Jack and Jill," with their pail, darkly outlined upon the moon. (Myths of Northern Lands, Guerber, 1895)
