Part 5/16:
The process Leedskalnin used to quarry and shape the limestone blocks is foundational to understanding his engineering feat. He reportedly employed a method involving large tripods constructed from nine poles of varying lengths—10, 20, and 35 feet—to manipulate heavy logs and equipment.
Building the Tripod Foundations
The process begins with selecting three small, three medium, and three long poles, which are arranged in a 3-way "X" pattern on the ground. Using chains, notches, and come-alongs, he would lift and stabilize the tripods. This chain and pulley system allowed him to erect towering tripods, reaching heights of up to 40 feet with careful assembly. These tripods served as the primary supports for lifting and moving the massive coral blocks.
