The term "fan vault" refers to an architectural style commonly found in English Gothic buildings such as the Westminster Abbey or King's College Chapel. The word is spelled using the IPA phonetic transcription as /fæn vɔːlt/, with the first syllable pronounced like "fan" and the second syllable like "volt". The term "fan vault" is derived from the shape of its vaulted ceiling, which is composed of intricately interwoven ribs that radiate outwards like a fan.
A fan vault is an architectural element found primarily in Gothic architecture, characterized by a series of concave ribs radiating from a central point, resembling the shape of an open fan. This intricate and decorative vaulting style is predominantly constructed using stone masonry, where the ribs gracefully curve upwards to form a complex pattern of arches and intersecting ribs. The fan vault is an evolution of the earlier Gothic rib vault, but it differs in its striking aesthetic appeal, intricate detailing, and geometric complexity.
Usually applied to the ceiling of a church or cathedral, the fan vault displays exceptional craftsmanship and structural engineering. As the ribs extend outward from a central boss, they divide and branch out, creating a web-like structure that supports the weight of the ceiling. By redistributing the force evenly across the entire surface, the fan vault provides strength and stability while simultaneously producing a visually stunning effect.
This elegant architectural feature became popular during the late medieval period and can still be admired in numerous historic religious buildings, particularly in England. Salisbury Cathedral and King’s College Chapel in Cambridge are exceptional examples of fan vaults. The airy and dramatic nature of the fan vault not only showcases the skill of Gothic craftsmen but also creates a sense of grandeur, heightening the spiritual experience within these sacred spaces.
The word "fan vault" is derived from two separate components: "fan" and "vault".
1. "Fan":
The term "fan" in this context refers to the intricate pattern created by radiating ribs, resembling a fan, in the construction of the vault. It is called so because of the resemblance to a handheld fan when viewed from below. The delicate ribbed structure spreads out from the base like the blades of a fan.
2. "Vault":
A vault, in architecture, refers to an arched structure that forms a ceiling or roof. It is often used to cover a significant open space, such as a hall, church, or cathedral. Vaults can be constructed using various materials such as stone, brick, or concrete.
Therefore, the etymology of "fan vault" derives from the fact that the intricate ribbed pattern created by radiating ribs in the construction of the vault resembles a fan.
