Transom (architectural)

Transom (architectural)

In architecture, a transom is the term given to a horizontal glazing bar which is framed across a window, dividing it into stages or heights.

Transom is the customary U.S. word for a traditionally fixed window over a door or an operating sash window. cite web |url=http://www.efficientwindows.org/glossary.cfm#t |title=The Efficient Windows Collaborative: Glossary |accessdate=2007-12-13] cite web |url=http://www.bigbluewindow.com/faq.aspx#q50 |title=What is a transom window? |publisher=Big Blue Window |accessdate=2007-12-13] In England, the transom above a door is usually referred to as a fanlight, and occasionally as an "overlight", or by the French word "vasistas".cite web |url=http://www.eurodict.koralsoft.com/VASISTAS+searchid-70270-ed_tr_en.html |title=Euro Dictionary: Vavistas |accessdate=2007-12-13] The word "fanlight" derives from the fan-like shape of early transoms, which became a traditional part of the Georgian style.cite web |url=http://freenet.buffalo.edu/bah/a/archsty/geo/index.html |title=Georgian Revival in Buffalo, NY |publisher=The University of Buffalo |accessdate=2007-12-13] "Vasistas" sounds similar to the German phrase "was ist das?" ("what is that?"); hence folk etymology ascribes its origin to a visiting German's reaction to seeing a transom during a trip to France.cite web |url=http://query.nytimes.com/gst/fullpage.html?res=9D05EEDB133CF930A15750C0A962958260 |title=A Droll Tale |publisher=The New York Times |accessdate=2007-12-13]

History

In early Gothic ecclesiastical work, transoms are only found in belfry unglazed windows or spire lights, where they were deemed necessary to strengthen the mullions in the absence of the iron bars, which in glazed windows served a similar purpose. In the later Gothic, and more especially the Perpendicular Period, the introduction of transoms became common in windows of all kinds.cite web |url=http://infomotions.com/etexts/gutenberg/dirs/1/9/7/3/19737/19737.htm |title=The Principles of Gothic Ecclesiastical Architecture, Elucidated by Question and Answer, 4th ed. |publisher=Project Gutenberg |accessdate=2007-12-13]
