“The cursed seventh son who becomes a slavering man-wolf under the Friday moon.”
Argentina's werewolf is not bitten into being; he is born to it. The Lobizón is the seventh consecutive son of a family of sons, doomed — in the belief of the Litoral, Paraguay, and southern Brazil — to transform on certain nights into a foul-smelling beast, part dog and part something worse, that haunts cemeteries and farmyards until dawn returns him, shaking, to his own skin.
The legend fuses the Guaraní Luisón, seventh and most cursed child of the primordial pair Tau and Kerana, with the Iberian werewolf carried in by colonists. The belief ran deep enough that seventh sons were feared and shunned — and Argentina eventually answered folklore with statecraft, making the President of the Nation the godparent of every seventh child in the land.
The Legend
The transformation is scheduled: Tuesday and Friday nights in most tellings, with the first change coming in adolescence. The beast is described as a large black dog, gaunt, ugly, and foul-smelling, with hanging ears, three-toed paws, and white eyes around blood-red pupils. It runs the cemeteries and rubbish heaps, eating carrion and filth, and in the darkest versions the flesh of the unbaptized dead.
In daylight the Lobizón is a man marked for those who know how to look: a heavy jaw, prominent veins, thin dark hair, old scars carried since childhood. The curse spreads, some tellings warn, by a kiss on the forehead or by passing beneath the beast's legs. By morning he remembers little — the folk portrait is less a predator than a prisoner, a man serving a sentence handed down at birth.
The Record
The custom that answered the curse is a matter of record. In 1907, immigrant parents from the Russian Empire asked President José Figueroa Alcorta to stand godfather to their seventh son, transplanting a custom of the czars; the practice took root, was extended to seventh daughters in 1973, and was fixed in law as no. 20.843 in 1974, granting the godchild a gold medal and an education scholarship.
The tradition made world headlines in December 2014, when President Cristina Fernández de Kirchner stood godmother to Yair Tawil, the seventh son of a Chabad rabbi — and reporters everywhere retold the werewolf story. The Argentine historian Daniel Balmaceda notes, deflatingly, that the presidential custom and the lobizón myth arose separately; folklore, as usual, had already merged them for good.
The Lore
The Guaraní root gives the legend its spine. Luisón, seventh son of Tau and Kerana, was the most dreadful of the seven cursed brothers of Guaraní myth, a creature of death whose territory was the graveyard. The belief traveled with Guaraní-speaking peoples through Paraguay and into the Argentine Litoral — Corrientes and Misiones remain its heartland — and spread more widely after the War of the Triple Alliance.
In Brazil the seventh son becomes the lobisomem; in Paraguay the Luisón proper still walks. The Argentine version wears its politics lightly: a folk terror so genuinely felt that the state built an institution against it, and the presidential godparenthood still quietly administers the remedy. Somewhere between Guaraní cosmology and the Casa Rosada, the seventh son found his protection.
