Symbol
a thing broken in two, so that the halves prove each other
The word this institute is named after does not describe a picture. It describes a protocol. From συμβάλλω, to throw together: a symbolon was an object — a knucklebone, a potsherd, a coin — deliberately broken between two parties, host and guest, creditor and debtor, so that each kept a half. Neither half meant anything on its own. The proof was the fit. Meaning did not live in the object; it lived in the join, and could only be produced by bringing the pieces back together. Only later does the word drift toward “sign” in general, and later still into the creed — the Symbolum, the token by which believers recognise one another. It follows that every plate in the Atlas is half a symbolon: the mark is the piece you are holding, and the culture that reads it is the piece you have to go and find.
