An aged count in Switzerland has an only son who can learn nothing, and sends him away for a year to a celebrated master. The son comes home having learnt what the dogs say when they bark. He is sent to a second master and learns what the birds say; to a third, and learns what the frogs croak. The father, in a fury, orders his servants to take the youth into the forest and kill him; they cannot do it for pity, let him go, and bring back the eyes and tongue of a deer as the token. The youth comes to a fortress whose old tower is full of wild dogs that must be given a man to devour at certain hours. He goes down to them without fear, and they wag their tails, because he understands them: they are bewitched to guard a treasure below the tower. He brings up a chest of gold, the dogs vanish, and the lord of the castle would adopt him as a son. On the road to Rome he passes a marsh and hears from the frogs what makes him thoughtful and sad. In Rome the Pope has died, and the cardinals have agreed to choose whoever is marked by a miraculous token; two snow-white doves fly onto the youth's shoulders as he enters the church. He is made Pope, as the frogs had said, and when he must sing a mass and does not know a word of it, the two doves sit on his shoulders and say it all in his ear.
The text is Margaret Hunt's 1884 translation (public domain), unabridged: all 946 words, every sentence verbatim and in order. Four voices on four bases: a narrator who tells it plainly; the father, an old man who shouts and whose death sentence is the quietest line he has; the son, mild, honest and in the tower perfectly calm; and the lord of the castle, bluff and frank, warning a guest of death like the weather.
The score is a cantus-firmus fantasia for chamber orchestra. The son's tune is a plain chant in F major on the oboe that sits in the wrong mode against his father's D-minor house and keeps its own time — that is what stupid sounds like — and in Rome it turns out to have been a Gregorian intonation all along, the cantus firmus of the mass the doves sing. The father's rage is that same tune upside down in D minor on the celli, the head only when he is dismayed, with horn and tremolo when he rages, tutti with a stab in the wrong key when he springs up, and in augmentation on the basses, pianissimo, for the sentence; his cry of Lord have mercy is the chant's head in minor, a Kyrie, and it comes back in Rome in F as the intonation of the mass. The three languages are three counterpoints learnt one a year: the dogs' howl (a rising minor sixth on the horn over a C-minor tremolo, which turns major on the clarinet when they wag their tails) and their bark in the bassoon; the birds' twitter in the flute, which slows in Rome into the doves' falling thirds on flute and solo violin; the frogs' two-note croak in bassoon and pizzicato basses, which becomes a passacaglia on the lament tetrachord for the prophecy, the tolling of tubular bells for the dead Pope, and the timpani pedal under the consecration. The mass at the end has all of them at once around the chant in augmentation, a plagal cadence with the whole ensemble held and released, and then the doves' two notes, pianissimo, in his ear. Sonatina Symphonic Orchestra through sfizz; no fade-out.
The diegetic layer is synthesized end to end: the father's chair and the son's bundle, the hounds at the first master's gate, the birdcages at the second, the water at the third, the heavy chair going over on the flagstones when the father springs up, the huntsmen's steps and a cloth folded in the bracken, the fortress gate, the lantern and the worn steps, the tower door's bolt, the dogs' tails and the basket emptied before them, the iron-bound chest set down on stone and its coins settling, the pilgrim's staff on the southward road, the frogs close in the marsh, the bells of Rome, two doves landing on his shoulders, a drop of oil, the pages of the missal, and the wild dogs howling under the fortress until the morning they are heard no more.
The art follows the rule installed eleven films ago: the narration is cut into 41 beats, one per narrated event, and each beat has its own picture whose prompt names the face of that moment — the father's chair and the son before it three times over, with the faces changing from hope to dismay to rage to cold. 34 of the 41 shots are stills — a FLUX.1-dev plate at native resolution, judged by a local vision model against the beat's intent, conformed to locked character sheets (the son, the father, the lord of the castle) with Qwen-Image-Edit-2511, judged again for identity, anatomy and head-count, upscaled and given a slow Ken Burns move. Only seven — the road into the first town, the father springing up, the road to the fortress, the dogs wagging their tails, the chest of gold, the frogs in the marsh and the doves alighting — are continued into motion by Wan 2.2 (16 generations). This is the first film under the body-traits rule (no prompt may name a missing part; a vision check looks at every sheet, plate, key and animated frame); this tale has no such character, so the rule is measured here as a baseline. The narration is the clock: each line's measured duration sets every cut and every bar.
