a Haʹdes corresponded with the Romans’ god of the underworld named Pluto. As applied to this god of the dead, the name Haʹdes meant “The Invisible-making Deity,” from his power to render human mortals invisible after their death.—See M’Clintock and Strong’s Cyclopædia, Volume 4, page 9, under “Haʹdes”; also, Liddell and Scott’s A Greek-English Lexicon, reprint of 1948, Volume 1, page 21, column 2, under Ἅιδης or ᾅδης.
