Final answer:
The differences between Hades and Gehenna hell lie in their origins and meanings—Hades is a Greek mythological neutral underworld with punitive areas, while Gehenna is a strictly punitive place of judgement in Judeo-Christian contexts.
Step-by-step explanation:
The differences between Hades and Gehenna primarily lie in their origins and the connotations associated with each. Hades, in Greek mythology, is both the name of the underworld and its king. The underworld is often depicted as a neutral place where all souls go, with distinct places like Tartarus for the greatest sinners and the Elysian Fields for heroic or virtuous individuals. In contrast to this, the concept of hell (Gehenna) in Judeo-Christian traditions, specifically in the New Testament, refers to a place of punishment for the wicked. The term often translates to a state of suffering after life, rather than a neutral resting place for all. While Hades includes a range of experiences from neutral to punitive and celestial, Gehenna is associated strictly with punishment and moral judgement.
The Gates of Hell, as depicted in artworks such as the sculptures from Dante's Inferno or medieval church portals, often portrays a scene of the Last Judgement, where the morally righteous and sinful are separated, with the latter facing eternal. These portrayals stem from Christian beliefs rather than Greek mythology, further distinguishing Gehenna's concept of hell from that of Hades.
