Question

In architecture, what is a shaft that leads to the springer of a rib or group of ribs, either rising from the ground or from a corbel at a greater height in the face of the masonry?

A. Trumeau
B. Fillet
C. Shaftlet
D. Ribshaft

Answer 1

A shaftlet is a small, slender column that connects to the springer of a rib or group of ribs in a vault, typically found in Gothic architecture and important for structural stability.

Step-by-step explanation:

The correct answer is C. Shaftlet. In architecture, a shaftlet refers to a small, slender, vertical column that leads to the springer of a rib or group of ribs in a vault. Springer ribs rise either from the ground or from a higher corbel located on the face of the masonry. These structural elements are typical in Gothic architecture, where they contribute to the pointed ribbed groin vault that characterizes the style.

Beth's mention of colonettes that divide into ribs to form the vaulting of a church, as well as the focus on verticality and stability, further emphasizes the importance of these supporting structures in Gothic vaulting systems. Ribs arising from shaftlets help distribute the thrust of the vault, ensuring the stability of the structure.
