Transom

 
Wikipedia: Transom (architectural)
A transom and transom light over double doors

In architecture, a transom is the term given to a transverse beam or bar in a frame, or to the crosspiece separating a door or the like from a window or fanlight above it.[1] Transom is also the customary U.S. word used for a transom light, the window over this crosspiece.[1][2] 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".[3] The word "fanlight" derives from the fan-like shape of early transoms, which became a traditional part of the Georgian style.[4] "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.[5]

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 stay 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.[6]

Transom windows which could be opened to provide cross-ventilation while maintaining security and privacy (due to their small size and height above floor level) were a common feature of office buildings and apartments before air conditioning became common.

Idiomatic usage

  • The phrase over the transom refers to works submitted for publication without being solicited. The image evoked is of a writer tossing a manuscript through the open window over the door of the publisher's office.[7]
  • Similarly, the phrase is used to describe the means by which confidential documents, information or tips were delivered anonymously to someone who is not officially supposed to have them.[8]
  • "Like pushing a piano through a transom" is a folk idiom used to describe something exceedingly difficult; its application to childbirth (and possibly its origin) has been attributed to Alice Roosevelt Longworth and Fannie Brice.
