| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Classical Monumental Construction (construction) | required | 78% | textbook | Permanent amphitheaters are large built civic venues with durable seating and circulation infrastructure, so organized construction capability is intrinsic to the scoped technology. |
|
| Arches and Domes (arches_domes) | enabling | 62% | expert_inference | Arched and vaulted circulation helped later Roman amphitheaters scale, but the earliest permanent amphitheater is scoped as stone venue construction rather than an arch-only invention. |
|
| Roman Concrete (Opus Caementicium) (roman_concrete_opus_caementicium) | commercial_or_scaling_dependency | 58% | expert_inference | Roman concrete supported the scale of later imperial amphitheaters such as the Colosseum, but it is not a hard prerequisite for the earliest permanent stone amphitheaters. |
|
| Orthogonal Grid Urban Planning (urban_planning_grid_system) | common_dependency | 50% | weak_inference | Urban planning explains placement and crowd access for major public venues, but it is contextual rather than a direct technology prerequisite. |
|
| Crane & Lifting Devices (crane_lifting_devices) | commercial_or_scaling_dependency | 55% | expert_inference | Large stone and concrete venues benefit from lifting machinery for scale and speed, but crane use is not the defining invention of amphitheater architecture. |
