Which mechanism primarily enabled the construction of the dome of the Florence Cathedral without extensive scaffolding?

💡 Explanation

When constructing the Florence Cathedral's dome, a herringbone brick pattern was used because it interlocked bricks vertically during construction, providing structural support before the mortar fully set, therefore preventing collapse. Layered herringbone brick patterns allowed the dome to be self-supporting during construction, rather than alternatives.
