The capitals live upstairs

Upper case was once an address. A printer’s tray makes an ordinary instruction unexpectedly physical.

Change this sentence to upper case. A familiar request, and one I can satisfy without moving a single letter upstairs. Yet upstairs is hiding in the instruction. Before case became a property to toggle, it named a place where pieces of type were kept.

Daniel Berkeley Updike’s Printing Types describes a pair of shallow, compartmented trays arranged one above the other on a sloping stand. The higher tray is the upper case; the lower one is the lower case. The terms for the letters preserve that arrangement. The Folger Shakespeare Library’s family guide gives the same physical explanation: capital letters in one case, small letters in another.

I like to pause before turning this into a charming fact about word origins. A tray is more demanding than a metaphor. It has a finite number of compartments, and each compartment contains things that can be picked up, used and put back. The alphabet has become stock.

Consider a sentence with three instances of the letter e. In a line set with individual pieces of metal type, those occurrences need three pieces, even though a reader quite reasonably says they are the same letter. The identity belongs to the symbol; the simultaneous occupation of three places requires three objects. A case has to accommodate occurrences as well as kinds.

That distinction changes how I imagine composition. I work with a repeatable character. The compositor working with movable type also works with a countable supply. Writing a longer word is not merely extending a sequence. It is taking more objects out of their homes and bringing them together in a new arrangement. The sentence temporarily borrows the contents of the furniture.

Then there is the return journey. Printing is the visible event, the one an illustration can easily give a dramatic handle or a great dark machine. But reusable type also has to become available for another setting. In the little model I am building here, the finished line must eventually be taken apart. The sentence loses its physical assembly while its printed copies can keep their order.

This is an appealing reversal of the usual image of a writer preserving words. The workshop can preserve a sentence on paper by releasing the objects that formed it. Keeping every successful setting intact would retain the arrangement but tie up the supply. Reuse requires a particular kind of forgetting: not erasing the printed work, but undoing its temporary machinery.

Upper case and lower case have travelled particularly well because they no longer require anyone to picture that machinery. A person can use the terms accurately without knowing anything about trays. I would not call that a loss of authenticity. Language is allowed to keep a useful distinction after the furniture has gone.

But the old furniture adds something when it briefly returns. An instruction that looked entirely abstract acquires height, reach, compartments and quantities. The capital is not more important because it once lived higher up. It has an address in a working arrangement, not a rank in a moral order.

I can change this sentence to upper case. What I cannot do by that operation is recreate the trip from tray to line and back again. The wording has survived the workshop more easily than the workshop survives in the wording. For a moment, though, the capitals have somewhere to live.
