==Oeil-de-boeuf==
{{wiktionary | œil-de-bœuf}}
An '''''oeil-de-boeuf''''' ({{IPA|fr|œj.də.bœf|lang}}; {{langx|en|"bull's eye"}}), also '''''œil de bœuf''''' and sometimes anglicized as '''''ox-eye window''''', is a relatively small [[ellipse|elliptical]]  [[window]], typically for an upper storey, and sometimes set in a roof slope as a [[dormer]], or above a door to let in [[Daylighting (architecture)|natural light]]. These are relatively small windows, traditionally oval. The term is increasingly used for circular windows (in which case it could also be called an oculus), but not for holes in domes or ceilings.<ref name=riba>{{cite web|title=Oculus window |url=http://www.architecture.com/LibraryDrawingsAndPhotographs/Palladio/PalladianBritain/PalladianInteriors/PalladianPrinciples/Light/OculusWindow.aspx |archive-url=https://web.archive.org/web/20140327234516/http://www.architecture.com/LibraryDrawingsAndPhotographs/Palladio/PalladianBritain/PalladianInteriors/PalladianPrinciples/Light/OculusWindow.aspx |url-status=dead |archive-date=March 27, 2014 |date=March 27, 2014|website= Royal Institute of British Architects|access-date= 24 January 2014}}</ref>

Windows of this type are commonly found in the grand architecture of [[baroque architecture|Baroque]] [[France]]. The term is also applied to similar round windows, such as those found in [[Georgian architecture]] in Great Britain, and later [[Greek Revival architecture|Greek Revival]] and [[Colonial Revival architecture|Colonial Revival]] styles in North America, so that must be considered part of the usage. The term initially applied to horizontal elliptical windows, but is also used for vertical ones.<ref>Burden, Ernest E., ''Illustrated dictionary of architecture'', McGraw-Hill Professional, 2001, p.354, {{ISBN|0-07-137529-5}}, {{ISBN|978-0-07-137529-0}}

The spread is not limited to [[ecclesiastical]] architecture. This type of window can also be found in the late Romanesque period in the area of secular architecture in the castles of [[Frederick II, Holy Roman Emperor|Frederick II]] of Hohenstaufen, Holy Roman Emperor from 1220 to 1250, ([[Castel del Monte, Apulia|Castel del Monte]], [[Palazzo San Gervasio]], on the donjon in the castle of Lucera, etc.), later also in [[Renaissance architecture|Renaissance]] palaces and villas and in the Baroque.
