Why these numbers

The game's own explanation, as a reader sees it in the backpack.

Stamina 46

You hold a torn piece of what was five whole books — most of Against Heresies is not in your hands, so Stamina is low.

Contend 66

History records Against Heresies as the argument that broke Valentinian Gnosticism — and in 2022, seventeen centuries later, the church formally honored Irenaeus as a Doctor of the Church. Proven results in battle: high Contend.

Defend 52

The complete work survives only in a Latin translation — most of Irenaeus’ original Greek is gone. A translated text is trustworthy but one step removed: a middling Defend.

Cited for this book

Named the 37th Doctor of the Church in January 2022 — Doctor Unitatis, the "Doctor of Unity." The full work survives only in a Latin translation; the Greek original is mostly lost.

Development

A book develops as it is read — the fragment becomes the work, the work becomes the corpus.

Moves learned

By levelling up. A book that develops keeps what it knew and learns the rest on its new schedule.

Read it: The Image of the King

The passages the Scriptorium holds on screen, word for word from a public-domain translation. Written in Greek, surviving chiefly in an ancient Latin translation.

“Error, indeed, is never set forth in its naked deformity, lest, being thus exposed, it should at once be detected. But it is craftily decked out in an attractive dress, so as, by its outward form, to make it appear to the inexperienced more true than the truth itself.”

Irenaeus, Against Heresies 1, preface 2 (trans. Roberts & Rambaut, ANF 1, public domain).

“Their manner of acting is just as if one, when a beautiful image of a king has been constructed by some skilful artist out of precious jewels, should then take this likeness of the man all to pieces, should rearrange the gems, and so fit them together as to make them into the form of a dog or of a fox, and even that but poorly executed.”

Irenaeus, Against Heresies 1.8.1 (trans. Roberts & Rambaut, ANF 1, public domain).

“…and should deceive the ignorant who had no conception what a king’s form was like, and persuade them that that miserable likeness of the fox was, in fact, the beautiful image of the king.”

Irenaeus, Against Heresies 1.8.1 (trans. Roberts & Rambaut, ANF 1, public domain).

“He will recognise the verses indeed, but not the subject to which they are applied… But if he takes them and restores each of them to its proper position, he at once destroys the narrative in question.”

Irenaeus, Against Heresies 1.9.4 (trans. Roberts & Rambaut, ANF 1, public domain).

“Such, then, is their system, which neither the prophets announced, nor the Lord taught, nor the apostles delivered, but of which they boast that beyond all others they have a perfect knowledge. They gather their views from other sources than the Scriptures.”

Irenaeus, Against Heresies 1.8.1 (trans. Roberts & Rambaut, ANF 1, public domain).

“The Church, though dispersed throughout the whole world… as if occupying but one house, carefully preserves it… For the Churches which have been planted in Germany do not believe or hand down anything different, nor do those in Spain, nor those in Gaul, nor those in the East, nor those in Egypt, nor those in Libya.”

Irenaeus, Against Heresies 1.10.2 (trans. Roberts & Rambaut, ANF 1, public domain).

“For the faith being ever one and the same, neither does one who is able at great length to discourse regarding it, make any addition to it, nor does one, who can say but little, diminish it.”

Irenaeus, Against Heresies 1.10.2 (trans. Roberts & Rambaut, ANF 1, public domain).
Notes

Irenaeus, bishop of Lyons, c. A.D. 175–185. The real title is Refutation and Overthrow of Knowledge Falsely So-Called; "Against Heresies" is what everyone actually calls it. Book 1 describes the Valentinian system in detail. Books 2–5 take it apart.

The mosaic is the whole argument in one image. The gnostics are not using different gems — they are using the same ones, rearranged. Every stone is genuine Scripture. The portrait is a fox.

And the answer is not to seize the gems back. It is to know what the king looks like. Irenaeus follows the mosaic with a forger who stitches real lines of Homer into a fake epic: anyone who knows Homer will recognise every line and reject the poem.

Note the test in 1.10.2, and notice it is a PUBLIC one. The same faith, taught the same way, in Germany and Spain and Gaul and Egypt — go and check. That is the exact opposite of a secret knowledge for the few, which is what he is arguing against.

His patience does run out. At 1.11.4 he mocks gnostic name-coining by inventing his own: a power he calls a Gourd, and with it Utter-Emptiness, which together produce a Cucumber, and alongside it a Melon. He then refers to "the remaining multitude of the delirious melons of Valentinus."

This is a torn piece of five books. The complete work survives chiefly in an early Latin translation — most of Irenaeus’ own Greek is gone.
