chariot
Enable an AI agent to recognise a chariot, assess its configuration and condition, and determine whether and how it may be displayed, handled, harnessed or operated.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise a chariot, assess its configuration and condition, and determine whether and how it may be displayed, handled, harnessed or operated.
A light, open, two-wheeled vehicle with spoked wheels, drawn by two or more horses hitched abreast, carrying a standing driver and often a fighter, used across Eurasia in the second and first millennia BCE for warfare, hunting, racing, and ceremonial display.
It can be Identify a candidate chariot and record the physical and documentary grounds for that identification.; Compare its assembled configuration with documented evidence and flag unsupported reconstruction choices.; Inspect the platform, running gear and draught connections for defects relevant to a proposed activity.; Assess compatibility with a specified harness, team arrangement and occupant load.; Determine supported methods for display, lifting, rolling or operation and record conditions that prevent an action..
Distinguishing features
Check for a wheeled, animal-drawn riding vehicle whose platform and body provide deliberate occupant stations; cargo space alone does not establish a chariot.
Examine wheel count, axle arrangement, body proportions and pole or shaft layout together; a two-wheeled configuration alone cannot distinguish a chariot from a cart.
Look for the relationship between occupant position, driving controls and draught connection, rather than identifying the vehicle from decoration or a historical label alone.
Distinguish a full-size vehicle or reconstructed vehicle from a depiction or miniature; incompleteness or present inability to roll does not by itself exclude a surviving chariot.
Scope
+ Identification as a chariot and differentiation from carts, wagons, carriages and representations
+ Platform, body, wheels, axle and their assembled relationships
+ Pole or shafts and interfaces to the draught team and harness
+ Occupant positions, access, balance and control arrangements
+ Surviving fabric, reconstruction, mechanical condition and activity-specific readiness
- Draught-animal identity, health, training and welfare
- Driver and passenger identity, competence and personal equipment
- Complete harness systems as independently managed objects
- Weapons, tactics, races and ceremonies in which the chariot participates
- Roads, tracks, terrain and operating venues as managed places
- Images, miniatures and textual depictions that represent a chariot without being one
Characteristics
- Identification basis
- physical configuration; documented identification; comparative attribution; disputed Makes the basis for calling the object a chariot explicit.
- Wheel and axle configuration
- record wheel count, axle count and wheel-to-axle arrangement; unknown where unobservable Supports recognition and determines how rolling and turning must be assessed.
- Wheel diameter and track width
- mm, with measurement points and uncertainty Constrains clearance, handling space and interpretation of vehicle proportions.
- Usable platform dimensions
- mm, distinguishing surviving dimensions from reconstructed estimates Defines the space available for occupants and their movement.
- Occupant arrangement
- number and positions of intended occupants; standing or seated provisions; unknown or disputed Connects body design to loading, access and control.
- Draught connection
- pole or shafts linked to documented compatible harness and team arrangement Prevents an assumed match between the vehicle and an arbitrary draught team.
- Balance under a stated load
- support reactions in N and load positions in mm, with test conditions Shows how occupant placement affects axle and draught-interface loading.
- Fabric and reconstruction status
- component-level original, repaired, restored, reconstructed, replica or undetermined Separates surviving evidence from modern choices that may affect appearance and operation.
- Activity readiness
- separately assessed for display, lifting, rolling, occupancy, harnessing and driven use: supported, conditional, prohibited or unassessed Avoids treating display stability or free-turning wheels as proof of operational fitness.

- No springing: shock through the axle throws or injures the standing crew.
- Horses killed, panicked, or entangled, immobilising the vehicle.
- Useless or lethal on broken, wooded, or muddy ground, which is why cavalry later replaced chariotry.

Regional variation
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Egypt: typically a two-person crew (driver and archer), axle toward the rear, used as a mobile bow platform.
- Hittite and Chinese practice: wider three-person crews (driver, archer, shield-bearer or spearman).
- Neo-Assyria: heavier boxes and crews of three or four, often three or four horses.
- Greece after the Bronze Age: rocky terrain pushed chariots out of war into games, weddings, and procession.
- Rome: racing and triumph only; no regular Roman field chariotry.
- Britain and Gaul: open-fronted vehicles used to deliver warriors who then fought on foot (Caesar; last battle use at Mons Graupius, 84 CE).
- China: many-spoked wheels, very wide track, prestige counted in 'a thousand chariots'; later command rather than shock use.
- India: Vedic ratha is the war chariot; the same word later names huge many-wheeled temple cars.
- English 17th-19th century 'chariot' names a four-wheeled carriage, not the ancient vehicle.

Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- cart - A cart is a two-wheeled load carrier, often with solid or cross-bar wheels and ox or donkey draught; a true chariot is light, spoked, horse-drawn, and built for a standing crew at speed.
- wagon or battle-wagon - Four wheels (often disk wheels) and a load or seated platform, as on the Standard of Ur; chariots have two spoked wheels. Kingpins and steering gear on finds mark wagons, not chariots.
- carriage called a chariot - A 17th-19th-century four-wheeled truncated coach with a forward-facing seat and coachman or postilion; it is not the ancient two-wheeled standing vehicle.
- ridden cavalry - The fighter sits the horse; on a chariot the horses are driven from a wheeled box and the crew stands.
- temple ratha or processional car - Large, often many-wheeled festival cars that carry a deity image at walking pace; the Bronze Age ratha/chariot is a light two-wheeled horse vehicle.
- south-pointing chariot - A Chinese mechanical directional carriage, not a war or racing chariot.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of chariot this model covers, and on what evidence? provenance

What the second pass must settle
- Which historical and regional uses of the name chariot should this registry entry include, especially where wheel count or occupant posture differs?
- What minimum surviving evidence is sufficient to identify fragmentary remains as a chariot rather than unidentified vehicle components?
- Should full-size ceremonial vehicles never intended to move under draught be included, and how should they be distinguished from representations?
- Which sources and assessment methods can support load, balance and operating limits for surviving examples and modern reconstructions?
- Where should the ownership boundary fall for detachable poles, yokes and harness fittings that may be catalogued separately?
