Hades came from the Greeks and was primarily a place of darkness. The word morphed from "Haides" which was originally Aionis and Aides (from aidos meaning "unseen"). Tartarus was below Hades and was a special prison for titans and involved torment.
The similarities are striking enough to make you wonder if these mythologies(egyptain, greek, roman) did not come from stories passed down through the ages originating from the children of Noah re-called from pre-flood times.
Inferno came from the Romans and incorporated the idea of flames and torment. It was ruled by Pluto who was also god of time and earth and wealth. Dante took "inferno" and popularized the idea of the devil tormenting souls in worse and worse ways as you went lower and lower into it.
Hel came from the Norsemen, it was ruled by a female god Hela and was the place for the departed dead who were not warrior heroes, who went to Valhalla.
The English (KJV)took all three and rolled them up into one and translated Sheol- meaning "the unknown"-which came to mean "the grave" among the Hebrews- into Hell, bearing all the mythological baggage of Hades, Inferno and Hel.
Hades (play /ˈheɪdiːz/; from Greek ᾍδης (older form Ἀϝίδης), Hadēs, originally Ἅιδης, Haidēs or Άΐδης, Aidēs (Doric Ἀΐδας Aidas
), meaning "the unseen"
) was the ancient Greek god of the underworld. The genitive ᾍδου, Haidou, was an elision to denote locality: "[the house/dominion] of Hades". Eventually, the nominative came to designate the abode of the dead.www.hell-is-a-myth.webs.com
