Why a well, of all places

A well is a hole with water at the bottom of it. Set out like that, it is an odd choice of place to put the things you most want.

People have been doing it for a very long time, across places that had no contact with each other, and they are still doing it now in shopping centres with ornamental pools and no water table involved at all. That persistence is worth looking at, as long as we are honest about how much of the story is actually known, which is less than most accounts of it imply.

What we can say with reasonable confidence

Objects have been deliberately placed into water at sacred sites across a wide range of periods and cultures. This is well attested in general terms. Springs and wells in the Roman world were often associated with a deity and received offerings, including coins. Coventina's Well in the north of Britain is among the better-known examples of a spring site that accumulated a substantial deposit of objects over a long period.

Beyond that level of generality I would rather not go, and this is where I part company with most writing on the subject. A great deal of what circulates about wishing wells is confident about matters that are not settled. What the people making those deposits believed they were doing, what they thought would happen, whether it resembled a wish in our sense or was closer to a payment, a thanksgiving, a disposal, or something with no modern equivalent at all, we do not really know. The objects survive. The reasoning does not.

The honest position is that we have the deposits and very little of the thinking that produced them, and reconstructing the second from the first involves more guesswork than the confident version admits.

The obvious part, which is the water

The water does not need much explaining. For most of human history, a reliable source of clean water was the difference between a settlement existing and not existing. A spring produces something essential, continuously, from underground, for no apparent reason and with no apparent supply.

It would be very strange if people had not treated that as significant. You do not need a theory of religion to arrive at the idea that the place where the water comes out deserves respect, and respect, in most systems, means leaving something there.

A well is the manufactured version of the same thing. Someone dug down until they reached the water, which means the well is a point of contact with something that was already there and was not put there by us.

The part I think is actually doing the work

But springs are not the only sacred thing that ever existed, and coins get thrown into wells far more than they are left on hilltops. So there is something about the specific shape of a well, and I think it is this.

You cannot get it back.

That is the entire difference between a well and almost any other place you might put something. Leave a coin on a shelf and you can pick it up. Change your mind, take it back, reconsider. Drop it down a well and it is gone in the completest way available. Not lost, which implies it might turn up. Gone to a place you know exactly and cannot reach.

That irreversibility is what makes the act count. A gesture you can undo is not much of a gesture. The reason a coin in a fountain feels like something happened, while merely thinking the same thought does not, is that one of them is finished and the other can be revised all afternoon.

Darkness, and not being able to see the bottom

There is a second property, harder to argue for but I think real. You cannot see down a well.

Look into one and there is a disc of reflected sky, your own head in silhouette, and then nothing. The depth is unverifiable from where you stand. It could be four metres. It could be forty. The sound the coin makes when it lands is the only information you get, and it arrives later than you expect.

Whatever you drop goes out of the category of things you can check on. That is a rare property in the physical world and it maps neatly onto what a wish actually is. A wish is a thing you cannot follow, cannot verify, and will not get a report on. The well is a place with the same shape.

I am speculating here and I want to flag that. Nobody left a record saying I chose the well because I could not see the bottom of it. But the practice has outlived every belief system attached to it, which suggests it is being held up by something in the physical arrangement rather than by any particular doctrine.

The coins, and why they are small

Coin-throwing turns up in a great many places and the coins are almost always low denomination. That is not stinginess. A high-value coin would turn the act into a transaction, and a transaction invites the question of whether you paid enough, and that question wrecks the whole thing.

What the coin has to be is an amount that costs you something and not very much. Enough that giving it up is an act. Not so much that you start calculating. Those two conditions leave a narrow band and people have settled into it more or less independently in different places, which is the sort of convergence you get when a practice is being shaped by what it has to do rather than by anybody's instructions.

It is worth adding that the coin cannot always have been a coin, since coins are relatively recent and the depositing of objects into water is not. Pins, small metal items, food, things people had. The coin is a modern stand-in for whatever was to hand. That it became standardised on money is convenient rather than meaningful. Money is simply the object everyone now carries a small amount of.

So a well gives you four things at once. Water, which was always significant. Depth you cannot check. A drop you cannot reverse. And a cost small enough to be paid without thought and real enough to make the moment count.

Nothing else in ordinary life assembles all four. A river takes your coin away but takes it somewhere, and rivers go places. A box keeps it and you can open a box. A fire destroys it entirely, and destruction is not the same as putting something somewhere. Only a well holds the thing permanently, in a location you know, that you cannot reach.

Whether anybody consciously worked this out is doubtful. More likely people tried various places over a very long stretch of time, and the one that felt right kept being used, and the ones that did not quietly stopped. That is how most old practices arrive, by attrition rather than design, and it usually leaves no record of the reasoning at all.

If you want the argument for what the act itself accomplishes, separately from where it happens, there is a piece on what you are doing when you make a wish. And the same shape appears in a form with no water involved at all, in letters written to people who will never read them, and in the general need for somewhere to leave something behind.
