Music

 * The music in Gehenna is titled Morning Star. "Morning Star" or "Shining One" is Greek for Light-Bringer or Lucifer.
 * The planet Venus is considered the Morning Star and is associated with the Devil falling from heaven. This is due to it falling beneath the horizon in the morning, much like how the former angel fell to Earth. Venus and the Devil share the name Lucifer because of this.
 * A morning star is also a type of weapon that consists of a spiked ball at the end of a club. An extremely brutal weapon that also resembles the rotating spike balls and the similarly named enemies unique to this floor.

Trivia

 * In Hebrew belief, Gehenna (or Gehinnom) was thought to be a small valley in Jerusalem. The name literally translated to "Valley of Hinnom" and in the Valley, Kings of Jerusalem would sacrifice their children through fire.
 * Gehenna was also thought to be "the destination of the wicked" in Jewish literature. It differs from the neutral-leaning Sheol as Gehenna was considered a type of waiting room; the longest one can be there is 11 or 12 months with few exceptions.
 * Although it is to be noted that Gehenna was also at first a grave, and later became a purgatory for those who entered. Individuals who entered would be judged for the deeds one did in life, along with their flaws and negative actions.
 * It was also thought to be the location of Jerusalem's garbage dump, where the city's waste and the corpses of criminals were disposed by incineration. These fires burned for most of the day, inspiring later descriptions of Hell as a place of eternal torment by fire for the wicked.
 * This floor could also potentially be a nod to The Seven Planes of Hehenna, a similarly named area in another of Edmund McMillen's games, Gish. This is reinforced by the numerous similarities the two share, such as the appearance of gimp-clad enemies and the visual theme of a demonic temple.
 * The boss Sisters Vis was also originally the boss of this area in Gish, though that is not the case for Gehenna.
 * As only has 2 unique bosses, it is possible to unlock it in one run by completing a Boss Challenge room, as both bosses will spawn.
