La Luz Mala: The Ghost Lights of the Argentine Countryside

On the flat immensities of the Argentine campo—where the horizon is a perfect circle, the nearest neighbor a league off, and the night sky comes down to the grass on every side—a light where no light should be is an event of the first order. The gauchos and the country people of the interior have a name for it, and the name is a verdict: la luz mala, the evil light. It appears after dark, most often in the dry months and by old superstition thickest around the feast of Saint Bartholomew at the end of August—the one day of the year, says the folk calendar, when the devil goes loose; it hovers at grass height or drifts above the fields, white, yellowish, or pale blue; it recedes when approached and follows when fled; and the whole weight of the tradition speaks through the standing counsel given to every child of the interior: do not ride toward it. For the luz mala, in the belief of the countryside, is no lantern and no traveler. It is a soul in pain—an alma en pena: the light of a dead person who did not receive Christian burial, burning over the place where the unquiet bones lie; or—the tradition's second article, held simultaneously and without any sense of contradiction—it marks buried treasure: the hidden gold of the old wars and flights, interred in leather bags and clay jars by owners who died with the secret, and guarded now by the very soul that buried it.

The Two Doctrines of the Light

The two readings—the grave and the gold—are one doctrine in the folk metaphysics, and the join between them is the treasure-lore of the whole Hispanic world: money buried with a death attached does not lie quiet. The entierro, the buried hoard, was real enough on the old frontier—banks were far, raids were near, and men interred their silver before battles and epidemics from which they did not return—and around the real practice the tradition built its law. The soul of the burier is bound to the hoard until the hoard is found and spent—ideally on masses for that same soul; the light is the soul's signal, burning where the digging should happen; and yet the light is mala, evil, dangerous to approach, because the guardian tests the finder. He who rides at the light greedy, frightened, or unprepared finds it recedes, vanishes, reappears behind him—the classic conduct of ghost lights on every continent—or, in the darker tellings, he finds it at last stationary, digs, and uncovers the jar; and the treasure of the impure-hearted turns in his hands: coals, bones, shards—the same reversal at the threshold that every deep tradition applies to the goods of the underworld. Some tellings add poison to the moral: the first breath of the opened jar—the vaho of the entierro, foul with generations of enclosure—sickens or kills the digger; the prudent opened such finds facing away, or let the jar air for a night. And the pious clause completes the code: treasure rightly found under a luz mala must be shared and sung for—alms and masses discharging the dead owner's bond—or the finder inherits not the gold but the ghost.

Against the light itself, the campo kept its precise etiquette. Meeting the luz mala on the night road, the rider does not gallop—flight draws it—and does not approach: he prays (an Our Father for the soul in pain is the classic prescription), bites the sheath of his knife or grips iron—the old apotropaic of the gaucho, steel between the soul and the uncanny—and rides on at a walk, leaving the light to its business. Children were taught to greet it, at distance, with the charity owed the dead: ánima bendita, blessed soul—for the second name of the phenomenon in parts of the interior is exactly that, la ánima, and the double name holds the double truth: the light is evil to the greedy and the rash, and a blessed soul to those who meet it with prayer and keep their distance.

The Science and the Sisterhood

The naturalists, of course, have their account, and the countryside has never much minded it: gases of decomposition—the phosphines and marsh vapors of buried organic matter—self-igniting over old graves and bone-yards; the dry-season phosphorescence of mineral salts; heat-mirage and refraction lifting distant lamps above the horizon of a country flat as still water. The accounts are respectable and, as always with the great folk figures, they explain the flame and not the faith. For the luz mala belongs to a universal sisterhood that no chemistry has retired: the will-o'-the-wisp of the English marshes and the irrlicht of the German moors—Böcklin painted her, a pale woman of light adrift over black water—the fuegos fatuos of Spain, the corpse-candles of Wales that traced the road of the next funeral, the treasure-lights of the Slavic lands that burn on Midsummer night over enchanted gold—and, on the luz mala's own continent, the golden fever that hunted El Dorado and the sacred lake of Guatavita, the greatest buried-treasure light of them all, which receded before its pursuers for three centuries in exactly the classic manner. Everywhere the syntax is identical: a light, low and wandering, on the boundary lands—marsh, moor, grave-field, the empty leagues—read as a soul showing itself, tied to unfinished business (a body unblessed, a hoard unspent), luring the greedy to harm and yielding, to the pure and the ritually careful, either treasure or the chance to do a mercy. The pampa, which has no marshes to speak of, gave the figure its own vast stage and its own hard clarity: on land utterly flat and utterly dark, the luz mala is the only feature of the night—the one point of address in an emptiness the size of the sea—and the tradition's whole counsel concentrates into the rider's choice at that single point: charity at a distance, or greed at a gallop.

The Esoteric Reading: The Light Over the Buried Thing

The esoteric reading of the luz mala hardly needs assembling; the campo did the work. Whatever is buried unblessed, burns. The unfinished dead of a life—the wrongs interred without rites, the wealth hidden with a death attached, the whole category of things put underground to avoid dealing with them—do not go dark; they luminesce: over the flat, featureless stretches of a soul's night, precisely where nothing should be, a pale light marks the spot. The tradition's genius is its double identification, which the psychologist and the alchemist would each recognize as half their science: the light is a soul in pain (the buried thing suffers and signals) and it is treasure (the buried thing is valuable—there is gold in the jar, for what we bury with such care is never worthless). And its ethics of approach are the complete manual for such lights wherever they rise. Do not gallop at it: greed and haste meet the receding light, the mocking distance, the jar of coals; the buried treasures of the deep are not seized by charge. Do not flee it: fled, it follows; the ignored signal attaches itself to the ignorer. Approach obliquely, armed with iron and prayer: discipline in one hand, charity in the other—for the finding is lawful only as a transaction of release: the gold is taken, the masses are paid, the soul unbound; treasure and mercy in one operation, or neither. And beware the first breath of the opened jar: what has been sealed underground for a generation exhales poison before it yields gold—let the opened thing air; the healers of buried griefs have no better rule. The light over the pampa is mala only in the sense that all threshold-powers are: evil to the unprepared, a blessed soul to those who ride up slowly, praying, with steel in their teeth—kin to every treasure the old world sealed behind a guardian, like the golden hoards of the barrow-lords of the north, which likewise come up only with their fight, and their dead, attached.

Rural Argentina reports her still: the lights of Salta and La Rioja and the deep province, seen from routes and ranchos, discussed in the same breath as gas pipelines and ghost stories; the Cerro de la Luz Mala of more than one province keeps its name on the maps; and the counsel of the grandmothers has not changed, because the phenomenon it governs—buried things signaling—has not changed and will not. Every flat dark stretch of a country or a life has its point of pale light. Ride toward it the right way. Pray first, for it was a soul before it was a signal; keep iron about you, for discipline is owed to the dead as much as to the living; dig only what you are prepared to release with alms and masses; let the jar breathe before you reach in. And if the light recedes as you advance—stop, make the sign, and leave it for the night when you come lighter-handed: the treasure of the campo, like every treasure under every wandering flame since the marshes of the old world first flickered, waits precisely as long as it takes the finder to become the kind of soul it was buried for.
