Artifact 12, recovered intact from a transit shrine, Late Screen Age.
The great illuminated altar stood upright against a wall, roughly the height of a kneeling worshipper, its face a lattice of gleaming offerings suspended in coils of wire. We name it the Wall of Withheld Bounty, and it is among the most theologically significant finds of the season. The Ancients arranged their sacred foodstuffs in perfect grids, each item visible yet unreachable, sealed behind a transparent membrane. Desire without access: the central discipline of their faith.
The rite is now well understood. A supplicant approached, fed thin metal discs or slips of pressed fiber into a narrow slot, and pressed a coded sequence upon a panel of worn buttons. The button surfaces show the heaviest wear at the symbols we translate as B4 and E7, suggesting these were the names of especially beloved deities.
In response, the altar performed its miracle: a single coil turned, and one offering fell into the reservoir below, delivered unto the faithful.
That the machine sometimes seized the disc and gave nothing, we interpret not as failure but as design. A god that always answered would command no fear. The dents along the lower flank of every recovered specimen, struck at the height of a closed human fist, confirm that the Ancients addressed their altar with passion, striking it, rocking it, pleading with it in the universal grammar of the abandoned prayer.
We picture them now: a people who could not simply take what they hungered for, who built temples in their halls of passage so that even the shortest journey might pause for an act of supplication. They wanted so little. A wrapped sweet, a cold vessel of colored water.
And still they knelt, and fed the wall their small coins, and trusted that the coil would turn.
