F16 — Wagon Driver / Ceremonial Procession: Nano Banana Pro Prompt Suite

Overview

Three prompt variants are provided for F16, each targeting a different scenario involving four-wheeled wagons in Hallstatt-period ceremonial and funerary contexts. All prompts are grounded in the evidence documented in investigation.md and cross-referenced against the Block 1 and Block 2 corpus files. Phase correctness and regional appropriateness have been verified for each variant.

Important note on the wagon type: All three prompts specify four-wheeled wagons exclusively. Hallstatt-period elite wagons were four-wheeled vehicles with spoked wheels and iron tyres. Two-wheeled chariots are a La Tene development and must not appear in any of these scenes.

Prompt Variant 1: Figure Leading a Four-Wheeled Wagon in Procession

Context

This prompt depicts a Ha D male figure — a handler or retainer — leading a pair of draught horses pulling a four-wheeled wagon along a dirt track, with an elite passenger seated or reclining on the wagon platform. The setting is the Western Hallstatt zone, consistent with the Hohenasperg/Hochdorf or Heuneburg landscape of rolling hills and tumulus cemeteries. The figure is a non-elite attendant whose role is inferred from the physical necessity of horse-drawn wagon transport (investigation.md, sections 6.2, 8.1, 8.2, 11.1). The costume is based on Ha D general male attire from situla art and textile evidence: belted wool tunic, single bronze fibula, leather shoes. The wagon design is based on the Hochdorf wagon reconstruction (B8_transport_equipment.md, entries 1-6; Pare 1992).

Positive Prompt

A standing man in his thirties walks beside a pair of draught horses, his left hand gripping the braided leather reins near the horses’ bridles, his right hand holding a long wooden goad with a sharpened tip. He wears a knee-length woollen tunic in a dark brown-and-ochre twill plaid pattern, belted at the waist with a thick leather belt fastened by a simple bronze hook clasp. A single bronze boat-shaped Kahnfibel brooch pins a short grey-brown woollen cloak at his right shoulder. His legs are wrapped in narrow woven wool leg wrappings wound from ankle to below the knee, cross-gartered with leather thongs. On his feet are simple rawhide leather turnshoes, creased and darkened with use. His hair is cropped short, jaw clean-shaven, and his head is bare. Behind him, a heavy four-wheeled wooden wagon rolls slowly forward on a rutted dirt track. The wagon has a flat rectangular plank body mounted on two fixed wooden axles, with four spoked wheels, each wheel having ten thick wooden spokes and a broad iron tyre band shrunk onto the rim. Bronze nave fittings cap the wheel hubs. The wagon body is reinforced with horizontal iron bands wrapped around the planking. On the wagon platform, an older man reclines against a folded woollen textile, wearing a finer dyed red-and-blue plaid tunic with tablet-woven borders, a gold neck torc, and a conical birch-bark hat. The two draught horses are stocky, thick-necked animals with dark bay coats, harnessed in pairs to a carved wooden yoke attached to a central wagon pole. Bronze phalerae decorate the breast straps, and jointed bronze bits sit in the horses’ mouths, with curved antler cheekpieces visible at the jaw. The landscape behind them shows gently rolling grassland under an overcast late-afternoon sky, with a large rounded earthen tumulus mound visible on a ridge in the middle distance. Scattered mature oak trees line the track. The light is diffuse, grey-gold, casting soft shadows. Photorealistic rendering, shallow depth of field, the focus on the handler’s weathered face and the horses’ tack, slight atmospheric haze, muted earthy colour palette of browns, ochres, iron-greys, and the dull gleam of worn bronze fittings.

Prompt Variant 2: Ritual Procession Scene — Strettweg Cult Wagon Composition

Context

This prompt recreates the scene depicted on the Strettweg cult wagon (Ha C, c. 600 BC, Universalmuseum Joanneum, Graz) as a life-size, living tableau. The central element is a tall woman — priestess or goddess figure — holding a large shallow bronze offering bowl above her head, standing on or immediately before a low four-wheeled ceremonial wagon platform. She is flanked symmetrically by armed warriors with round shields and hafted axes, mounted horsemen, and figures leading antlered stags. The scene is set in the Eastern Hallstatt zone (Styria/southeastern Alps). The composition follows the bilateral symmetry of the bronze model but translates the schematic figurines into fully realised human figures with Ha C Eastern Hallstatt costume. The Strettweg wagon is Ha C, so no Ha D artifact types (Certosa fibulae, Negau helmets, gold torcs) may appear. (Investigation.md sections 9.1-9.4; 07_situla_art.md section 4.7; Egg 1996.)

Positive Prompt

A ritual procession tableau in an alpine meadow clearing, composed symmetrically like a bronze votive sculpture brought to life. At the centre, a tall woman stands rigidly upright on a low four-wheeled bronze-fitted wooden platform wagon, her bare arms raised fully overhead, both hands pressing flat against the underside of a wide shallow bronze offering bowl roughly sixty centimetres in diameter, its interior gleaming with a thin layer of barley grain. She is taller and more imposing than every other figure in the scene, her bearing hieratic and frontal. She wears a long undyed linen shift reaching her ankles, loosely draped, leaving her arms bare from the shoulders. Her hair is pulled back tightly against her skull, and her expression is solemn, abstracted, her gaze fixed forward. On either side of the bowl, two diagonal bronze struts angle from the wagon platform upward to brace the vessel — X-shaped supports of cast bronze. Flanking her on the platform stand four warrior men, two on each side, arranged symmetrically. Each warrior holds a round wooden shield covered in leather, roughly fifty centimetres across, in one hand, and a bronze-bladed axe with a wooden haft in the other hand. The warriors wear knee-length wool tunics in dark un-dyed brown, belted with plain leather belts, each fastened with a bronze Kahnfibel boat-shaped brooch at the left shoulder. Their heads are bare, their hair cropped short. Forward of the platform on each side, a mounted horseman sits astride a small sturdy horse without saddle or stirrups, gripping the mane and a set of simple rope reins. The horsemen wear similar brown tunics and each carries a short bronze-headed spear upright. At each end of the composition, a man leads a full-grown red deer stag with a magnificent rack of antlers by a rope halter, guiding the animal forward as if toward sacrifice. The stag-leaders wear rougher woollen garments and rawhide shoes. The processional wagon has a flat rectangular open-work bronze-decorated platform on four small spoked wheels, each with eight spokes and narrow iron tyres. The setting is an upland clearing in the southeastern Alps, surrounded by dark spruce forest, with a rocky mountain slope visible in the distance under a pale grey morning sky. Thin ground mist curls around the wheels and the hooves of the horses. The light is cool, diffuse, early morning, casting no harsh shadows. Photorealistic rendering, wide shot to capture the full symmetrical composition, the bronze bowl catching a gleam of grey light, the colour palette dominated by undyed wool browns, dark forest greens, the grey-bronze of metal, and the warm red-brown of the deer hides.

Negative-Constraint Tail

No two-wheeled chariots, no La Tene equipment, no Certosa fibulae, no Negau helmets, no gold torcs, no gold jewellery, no Mediterranean imports, no Greek pottery, no wine amphorae, no Schnabelkannen, no swords (axes only for the warriors in this scene), no plate armour, no chainmail, no stirrups, no saddles, no horseshoes, no Celtic knotwork, no tartan, no kilts, no fantasy elements, no magic effects, no glowing light, no supernatural elements, no modern buildings, no paved surfaces, no Christian symbols, no medieval architecture, no AI-generated “Celtic” stereotypes, no horned helmets, no winged helmets, no togas, no Roman military equipment.

Prompt Variant 3: Funeral Procession with Body on Wagon Approaching a Tumulus

Context

This prompt depicts a Ha D funeral cortege in the Western Hallstatt zone (c. 530-500 BC), inspired by the Hochdorf and Vix burial contexts. A deceased chieftain lies on a four-wheeled wagon, draped in fine textiles, surrounded by grave goods. The wagon is drawn by a pair of horses toward a large partially constructed tumulus mound. Mourners and retainers walk alongside carrying feasting equipment and weapons. The scene synthesizes evidence from: wagon burial practice (04_burials.md section 4.2; Pare 1992), the funerary sequence (04_burials.md section 6.2), feasting-as-funerary-ritual (04_burials.md section 6.3; Dietler 1990; Arnold 1999), and the Vix landscape evidence for a processional approach to the tumulus (investigation.md section 11.2). No specific burial documents the appearance of such a procession, so this scene is a composite reconstruction flagged as speculative.

Positive Prompt

A solemn funeral procession moves slowly across a wide grassy plain toward a massive half-built earthen tumulus mound rising against an overcast sky. The mound is roughly sixty metres in diameter and four metres high at this stage of construction, its flanks of raw brown earth exposed, with a dark opening at the base where a timber-lined burial chamber yawns open, its squared oak beams visible. At the centre of the procession, a heavy four-wheeled wooden wagon rolls forward, drawn by two dark bay horses harnessed in a paired yoke, their heads lowered, bronze bits and curved antler cheekpieces visible at their jaws, bronze phalerae glinting dully on the leather breast straps. The wagon has a flat plank body on two axles, four ten-spoked wheels with wide iron tyre bands, the entire body reinforced with horizontal iron banding, and the wood dark with age and oil. On the wagon platform lies the body of an older man, approximately fifty years of age, laid supine on a thick wool textile in deep red-and-blue twill pattern, his arms at his sides. He wears a fine knee-length tunic of dyed wool with tablet-woven gold-and-red borders at hem and cuffs, a gold neck torc of twisted rod with buffer terminals resting against his collarbones, gold-covered leather shoes on his feet, and two gold serpentine fibulae pinned at his chest. A short iron dagger with a gold-sheeted hilt lies along his right thigh. His eyes are closed, his face composed, his skin pale and waxy. His birch-bark conical hat rests beside his head. Around the body on the wagon platform are arranged grave goods: a set of nine drinking horns of dark aurochs horn with gold lip bands, a stack of shallow bronze serving dishes, and a massive Greek bronze cauldron with three small lion figures perched on the rim, its surface green with patina. Walking beside the wagon on the left, a younger man in a plain brown wool tunic guides the horses by the bridle with one hand, his other hand resting on the wagon rail. Behind the wagon, six men walk in two files of three, carrying objects for the burial. Two carry long iron-tipped spears upright. Two carry between them a large rolled textile hanging on a wooden pole across their shoulders. Two carry ceramic vessels — tall conical-necked painted urns with geometric red-and-white Hallstatt painted ware decoration. To the right of the wagon, three women walk in file, wearing long woollen dresses reaching the ankle, belted at the waist with decorated bronze belt plates, their hair bound up with bronze ring-headed pins, and heavy hollow bronze ankle rings visible above their rawhide shoes. They carry woven baskets. A mounted warrior on a small horse brings up the rear of the procession, wearing a belted tunic, a bronze arm ring, and carrying a round shield and a short spear. He wears no helmet. The sky is flat grey, a late autumn afternoon, the light cold and even, the grass tawny and drying. A line of bare-limbed oaks edges the plain. In the far distance, two more tumulus mounds break the horizon line, old and grass-covered, belonging to earlier generations. Photorealistic rendering, medium-wide shot, the wagon and body in sharp focus, the tumulus entrance looming in the near background, the colour palette muted autumnal: tawny grass, grey sky, raw earth brown, the dull gleam of bronze and gold against dark wool textiles, the faded red and blue of dyed fabrics.
