Oppressum Tyrannus is considered as a monographic formless about techniques, procedures and result of experiences of contact of the third type with the Demon; such is the spirit of the text.
In spite of being the second volume of a work until now lost, Oppressum Tyrannus is presented with unitary content that develops and concludes inside their context.
It is not a book of hermetic disclosure since its language is not structured so that the reader understands and accepts his postulates, neither it is one mere collection of rituals.
Contrary to the traditional books of Satanism Oppressum Tyrannus doesn't adopt a philosophical position, neither of adoration and submission before the Demon; the author makes an aseptic analysis of the phenomenology and marks the energy weaknesses which the malignant spirit at the time of his appearance in this material plane incurs.
Here the magician's attitude is not that of a devote one but rather he is a tamer of demons that is able to control the situation and obtains benefits with the contact.
