This week, we return to one of my favorite things: architectural jargon!
While you may think of it as useless architectural history, I promise you that it will come in handy someday during a trivia Tuesday.
Trust me.
Someday, someone will be impressed with your knowledge of oriel windows.
So, what are they exactly? My handy-dandy Guide to Vermont Architecture uses the following definition:
“Multi-sided window that projects from the wall of a building, and whose base does not reach the ground.”
If the window starts on the first floor then you can call it a “bay” window; bay windows can be more than one story in height much like oriel windows.
Another definition comes from Thought Co.:
“An oriel window is a set of windows, arranged together in a bay, that protrudes from the face of a building on an upper floor and is braced underneath by a bracket or corbel.”
Here’s a definition of oriel windows from John Britton’s, A Dictionary of the Architecture and Archaeology of the Middle Ages: Including Words Used by Ancient and Modern Authors in Treating of Architectural and other Antiquities: With Etymology, Definition, Description, and Historical Elucidation: Also, Biographical Notices of Ancient Architects, which was printed in 1838:


So, where’d the idea of these windows come from you’re probably wondering!
Well, oriel windows most likely originated in the Middle Ages, not just in Europe but also in the Middles East.
In Europe, it may have developed from the word for porch or gallery, “oriolum,” which is medieval Latin. As you can see there’s a connection between the words, “oriel” and “oriolum.” Merriam Webster’s dictionary points to the first known usage of the word in the 14th century while the Encyclopedia Britannica says “oriel” became “prevalent” in the 15th century and were often placed over gateways or entrances to manor houses and public buildings.
So why would you want an oriel window- besides using it to spy on who’s coming to the manor for dinner tonight? It also allowed more light into a room and expanded the flood plan. The window style also offered a way for air ventilation and keeping a room cooler, which would have been ideal in the Middle East. In the Middle East, this style of window first appeared in 12th century Baghdad during the Abbasid Period. The window was called, mashrabiya, and were known for their ornamental lattice screens. In the Middle Eastern architecture, they were typically found on the side of the buildings and/or on the courtyard side of a house. Through the ages, the mashrabiya often would be designed based on the current architectural styles of the time, for example during the 1920’s and 1930’s, the mashrabiya lattice work was inspired by the Art Noveau and Art Deco styles.
Here in the United States, oriel windows can be found on a variety of buildings with different architectural styles, such as: Tudor Revival, Gothic Revival, and Queen Anne.
In another exciting book found on Google Books, here’s instructions on how you would have constructed an oriel window in the 1840’s as detailed by Alfred Bartholomew in Specifications for Practical Architecture, Preceded by an Essay on the Decline of Excellence in the Structure and in the Science of Modern English Buildings; With the Proposal of Remedies for those Defects:
