1. Planning and Preparation:
* Site Selection: The pyramid was built on a carefully chosen site, likely due to its proximity to natural resources and the presence of a powerful spring.
* Foundation: A massive foundation was laid out, likely with a mix of earth, gravel, and clay. This ensured a stable base for the immense structure.
* Ramp: A long, gradual ramp was constructed along one side of the pyramid. This served as a pathway for moving materials up to the construction level.
2. Building the Pyramid:
* Adobe Bricks: The primary building material was adobe bricks, made from sun-dried mud mixed with straw for strength.
* Layered Construction: The pyramid was built in a series of layers, starting with the base and gradually ascending. Each layer consisted of a platform of adobe bricks, covered with a layer of earth, gravel, or volcanic rock.
* Human Power: The bricks and other materials were transported up the ramp using human labor. Workers likely used wooden rollers, sleds, and levers to aid in this arduous process.
* Internal Chambers: As the pyramid rose, internal chambers were built within the structure, possibly for religious ceremonies or burials. These chambers may have been accessed through tunnels or hidden passages.
3. Finishing Touches:
* Exterior Plaster: Once the pyramid was built, the exterior was covered with a smooth layer of plaster, creating a polished and finished surface.
* Decoration: The pyramid was likely decorated with murals, mosaics, and painted designs, though much of this has been lost due to erosion and weathering.
4. Ongoing Development:
* Expansions and Modifications: The Pyramid of the Sun was not built in a single, continuous construction phase. Over time, it underwent multiple expansions and modifications, likely reflecting the changing needs and beliefs of the Teotihuacan people.
Tools and Techniques:
While the exact tools and techniques used are still being studied, evidence suggests that the ancient builders used:
* Copper and Obsidian Tools: For cutting and shaping the stones and adobe bricks.
* Wooden Tools: For moving and manipulating materials.
* Simple Machines: Like ramps, levers, rollers, and sleds, to move heavy objects.
Important Note: The construction of the Pyramid of the Sun involved an immense amount of labor, likely requiring the work of thousands of people over many years. This highlights the sophistication and organization of the Teotihuacan civilization.
