The context of this article is within the historical Hellenic oracular Greek mystery or Orphic-initiatory tradition.
It was guided by ritual, and we dont know everything about it.
A thanasimon is a "Death Inducer" φάρμακον (pharmakon), sometimes called "the storm". Used within a Mystery rite where a controlled "near death" experience produces a transformative insight in the initiate's understanding of the order / kosmos, changing their inner (self) consciousness and outer (social) consciousness to be more harmonious and less opposed.
The Thanasimon system did not treat venom solely as a poison; in controlled doses, Greek physicians and mystery-priests regarded it as a tool for conditioning, endurance, and even visionary states - an idea documented across Nicander, Galen, Aelian, and the PGM.
These rites belonged to priesthoods - often described under serpent imagery such as Drakon or Echidna (δράκων, ἔχιδνα, ὄφις) - who possessed inherited pharmacological knowledge of venoms, antidotes, youth-conditioning, and microdosed toxology. Their authority derived from their technical control over dangerous pharmaka and guidance of the initiate in the Aion to create harmony with their daimones, often encoding their authority into mythic symbolism like the Gorgons and Snake imagery, and the medical Caduceus used in Asclepian healing centers.
The pharmacological power lies not in the venom alone but in the binary two-stage rite: induction into crisis (Thanasimon), and controlled restoration through its antidote Galene. This binary appears centuries before theriac, already fully formed in Asclepian, Hippocratic and Nicandrean toxicology.
The ‘death’ in this context is physiological, not metaphorical: a controlled collapse of vital signs induced through toxic pharmaka, followed by revival through antidotal galene, forming a literal enactment of the death–rebirth cycle.
Because such compounds were lethally dangerous, their use was restricted to hereditary serpent-priesthoods...
The journey of the initiate is guided by an administrator (e.g. a priestess, or a prophet), into and out of this "death" state, in order to "educate" their consciousness in a guided journey of "death" and "resurrection", where the initiate is "reborn", their Soul/Psyche educated or molded.
To pull the initiate out of the near-death state, and save their life, an antidote called Galene is applied, sometimes called "the calm".
These rites often culminated in induced visions (θεωρίαι), sometimes through medicated salves (kollouria) applied to the eyes or skin, paralleling the PGM instructions to ‘see the gods walking.’
The rite was structured around a deliberate polarity: the Thanasimon as “the storm” (violent upheaval of body and psyche) and the Galene as “the calm” (the re-establishment of order). This binary—ordeal and restoration—was foundational in Greek pharmacology, mystery initiation, and Asclepian healing.
Many ancient testimonies—from Nicander to Aelian to Galen—indicate that such rites often involved initiates in early youth (νεανίσκοι), who were trained or habituated to pharmaka from a young age.

The older Greek pharmacological horizon already operated with a binary contrast between θανάσιμον (thanasimon) and γαλήνη (galene) — the death-bearing and the calming.
Against these stood the agents of γαλήνη (galene), restoring bodily and psychic stillness:
So, Before theriac (θηριακή) emerges as the master panacea drug, Greek pharmacology operated with a binary pattern:
Sounds harsh to "induce death" on purpose, why?
Because near death experience (NDE) is associated (today) with causing a mystical experience, and mystical experience has the power to heal the soul and psyche through a unity mindset experienced during the time.
It was harsh by design: a technology to induce NDE for the purpose of molding a better person. NDE is very risky. So having a technology to control such an experience while minimizing harm, is ideal.
Healing through education of the soul and psyche was thought to heal the body, for a time, at Asclepian medical centers. Which was basis of Asclepian medicine until Galen started pruning the Hippocratic corpus of its less science-based material.
In ancient medicine and rites, human beings were exposed, so they could fill the role of soteria (savior) during initiation rites. Using a bandage around cuts on their arms, or thin tissues.
Thanasimon comes from Hellenic mystery and Orphic-initiatory tradition
The structure of the rite consistently features:
Within the historical Hellenic and Orphic context, death-and-resurrection rites involving pharmaka like the Thanasimon were carried out primarily by specialized mystery cults, with a few identifiable groups or priesthood roles:
Summary:
Within mystery / Orphic-initiatory contexts, the Thanasimon is:
Guidance is key. Especially to ensure repeatability. The rite aims to synchronize the initiate to the right mental mindset to guide them to the intended outcome.
We know that from the Eleusinian mysteries, that mental imagery was a journey to the underworld and return from it (death and resurrection is a common theme). Centered around the story of Persephone and Hades. Persephone the parthenos virgin/maiden travels to the underworld, marries Hades, becomes Queen of the underworld, and comes back to the living world as a new person.
The guidance of the rite creates this imagery in a pliable mind, which aligns it's revelation to some constraints.
The goals are similar to modern psychedelic-assisted therapy (analogy, not literal equivalence). But more aligned with releasing fears through realization that we are all one and that we are the leader of our "self", and our leadership relationship with others is best done constructively than adversarially (self-mastery, ethical responsibility, and social harmony all emerges here). Roughly...
Thanasimon is primarily reconstructed from textual and pharmacological sources; no full ritual manuals survive, so our understanding relies on cross-referencing Galenic, Dioscoridean, Orphic, and magical papyri evidence.

Theriac of Mithridates.
By this King Mithridates always used for the sake of protection against a θανασιμον/thanasimon death-inducer. When indeed he was captured by the Romans, having twice drunk a death-inducer and not being able to die, he used a sword upon himself.
It works against the θανασιμον/thanasimon (death-inducing) pharmaka, and every ios (venom) arrow-poison casting strike, and the internal disorders.
This was used by Andromachus. The preparation is as follows:
of squill cakes, forty-eight;
of theriac cakes, black pepper, sweet-spice compound, and juice of Spanish poppy, twenty-four of each;
of dried roses, skordion, seed of bunias, and Illyrian iris...
ἐκ τῶν δὲ πρώτων πρῶτον ἄρξομαι λέγειν·
ἔσωσά σ᾽, ὡς ἴσασιν Ἑλλήνων ὅσοι
ταὐτὸν συνεισέβησαν Ἀργῷον σκάφος,
πεμφθέντα ταύρων πυρπνόων ἐπιστάτην
ζεύγλαισι καὶ σπεροῦντα θανάσιμον γύην·
But from the beginning I shall begin with the first thing:
I saved you, as all the Greeks know who boarded the Argo with you,
when you were sent to become master of the fire-breathing bulls,
to yoke them beneath the harness,
and to sow the death-inducing field.
And right after that:
and the dragoness, who, encircling the all-golden fleece,
guarded it with his coils through the night, not yielding to sleep,
having slain him, I raised up for you the salvific light.
Taken literally, this doesn't quite compute.
Take metaphorically, given what we know about Medea, Echidnaic Priesthood, and mystical schools:
That fits the myth perfectly.
That γύη remains “field,” but the field itself is a metaphorical mental state in which a death-inducing transformation is seeded.
Where is the teeth? The reader fills in the dragon teeth detail because the Argonaut myth is famous. The actual dragon’s teeth episode is told elsewhere in the Argonaut tradition. For example, in Argonautica, Aeëtes gives Jason a task:
Apollonius explicitly mentions the teeth. Euripides does not.
He simply references the entire episode by naming two parts everyone would recognize:
In fact, that’s one reason the phrase θανάσιμον γύην stands out. Euripides could have said something like:
So if you’re doing close reading, the text is not drawing attention to the teeth. It is drawing attention to the field and its death-inducing character.
The teeth belong to the larger myth that Euripides expects the audience to supply from memory. The word for teeth (ὀδόντες) does not appear in this passage.

How many ritual-killings and destructive means of death-inducing pharmaka women have discovered against men.
ψυχὴν ἀντὶ ψυχῆς καταθέσθαι δικαιοῦντος τοῦ νόμου.

No one shall possess a drug (Φάρμακον/pharmakon), neither death-inducing (θανάσιμον/thanasimon) nor one prepared for other kinds of harm against Israelites. And if anyone is discovered to be in possession of it, let him be put to death, suffering this very thing which he had prescribed for those against whom the drug had been prepared.

δαιμόνια ἐκβαλοῦσιν, γλώσσαις λαλήσουσιν καιναῖς,
18. καὶ ἐν ταῖς χερσὶν ὄφεις ἀροῦσιν· καὶ ἐὰν θανάσιμον τι πίωσιν, οὐ μὴ αὐτοὺς βλάψῃ· ἐπὶ ἀρρώστους χεῖρας ἐπιθήσουσιν, καὶ καλῶς ἔξουσιν.
18. They will pick up serpents (ὄφεις/ophis); and if they drink the death inducer (θανάσιμον/thanasimon), it will not hurt them; they will lay hands on the sick, and they will recover."
The term θανάσιμον (thanasimon) appears in Mark 16:18 in the Greek New Testament, where it is translated as "death inducing", which means "deadly" or "poisonous." In this context, it refers specifically to serpent venoms that could cause death. And they're talking about immunity to those venoms, curiously enough.
And how do we get immunity to venoms?
Venoms were a potent pharmakon in antiquity, one of the 3 saviors of ancient antiquity (herbal, mineral, and beastly venoms).

-σιμον would indicate “capable of causing,” so combined with θανά- it literally means: “death inducer”
