| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Basic Woodworking (woodworking_basic) | historical_predecessor | 76% | textbook | Classical hoists used wooden lever arms, frames, winches, sheaves, and ramps, making woodworking a recurring construction substrate rather than a unique invention step. |
|
| Basic Rope Making (basic_rope_making) | required | 84% | textbook | The scoped Classical hoisting systems transmit force through ropes in pulleys, block-and-tackle, winches, and hauled ramps; rope is a direct component dependency. |
|
| Wheel and Axle (wheel_and_axle) | enabling | 78% | textbook | Pulley wheels and winch drums are rotating wheel-and-axle mechanisms; this edge supports the pulley/hoist part of the scope, while levers and ramps can exist without it. |
|
| Mathematics (mathematics) | enabling | 72% | review | Archimedean lever theory and Hero's analysis of simple machines formalized mechanical advantage, but practical hoisting equipment existed as craft machinery before full mathematical treatment. |
