The band name influenced by Hieronymus Bosch, the painter of hell and hell itself. Hieronymos in Greek means holy-named and inferiorum in latin hell, so holy-named hell. Band's thematology related with satanism and the apocalypse, occultism(rituals of demonic invocations) and influenced by old horror movies(about witchcraft, especially by the movie "Cry of the Banshee"). The founder and the only member of the band had the idea to create the band in prison(prison transfers) as the police had arrest him as they found on him a knife and at his home a human skull stolen by the local cemetary painted in black color, satanic symbols at his room(posters with 666, pentagrams and other symbols made by him), Black Metal/Death Metal music and occult books. The prosecutor sent him at Dahou of Penteli(a sanatorium on mount of Penteli) where he spend 6 mounths of his life among children and teens who suffered from softer to heavy mental problems. Best things he did there was listening to black metal music, talking with the blonde nurse-rock listener and a good female friend- and having endless walks, alone, in the woods and caves(full of bats) of mount Penteli. After 6 months the psychiatrists who examined him found that he never suffered from any mental disease and thus the beast was free again. This happened during 1992-1993, when the case of the Satanists of Palini had also see the lights of media. The leader of the band since 2000 is no longer a satanist, darkist, occultist and black metal listener and musician but a paganist.
