The Greek μαντικόν means "the prophetic": the faculty, or the art, of seeing forward. Plato uses the word in the Timaeus for the part of the soul that foresees, and in the Phaedrus for the oracle's gift, which he ranks above ordinary good sense. What the Greeks also knew is that an oracle never decides. Its sayings are weighed by interpreters, and only then do they become a course of action.
That is the model Mantikon is built on. The council of models is the oracle: it sees forward from the data and argues what it sees. The organization is the interpreter: it reads the verdict, the reasoning and the dissent, and acts, or overrules. The decision is what the two settle on together.
The name has eight letters, three syllables, and reads the same in English, German, Ukrainian and Russian. Its eight capitals are also the same in Greek, ΜΑΝΤΙΚΟΝ, which is why the K stays and a C would break it. A second reading is the manticore, the creature with a human face; the project keeps the first.
Palantír, the seeing-stone of Tolkien's tales, sees far: it shows what is. Mantikon sees forward: it argues what should be done. The two words are the same age and the same length, and they are not the same claim.
