The idea of the band was born in Larissa-Hellas in 1996 by Corax S. (Jackal’s Truth) & Stefanos Koutsomarkos (Jackal’s Truth, etc.), however, the material form took part for a first time in 2011. The recordings were never officially released. In the beginning of 2019 the band regathered, to write & compose the “Philosophical Chapter” and to re-write & re-compose their previous “Dionysian trilogy” under the name of “Mythistorical Chapter”, with the addition of A.Z. (Kawir, ex-Obsecration, etc.) and the later addition of Melanaegis (ex-Kawir, ex-Rotting Christ [live]). In the beginning of the pandemic period (Covid-19) both Stefanos & Melanaegis left the band. Meanwhile, Thyrathen moved on to a formal cooperation with its (5-membered) lyrical line-up, as well as, with: Alexandros (Macabre Omen, The One, Razor of Occam etc.), and Stefan Necroabyssious (Varathron, Katavasia, Zaratus, etc.), who both participated as the lead singers and the main narrators of the album.
