[[File:Saint Andrew%27s cross.svg|thumb|right|A diagonal cross (decussate cross, saltire, St. Andrew's Cross)]]

A '''saltire''', also called '''Saint Andrew's Cross''' or the '''crux decussata''',<ref>{{cite web |title=Crux decussata |url=https://www.merriam-webster.com/dictionary/crux%20decussata |website=Merriam-Webster Dictionary |publisher=Merriam-Webster, Inc. |access-date=July 24, 2018}}</ref> is a [[Heraldry|heraldic]] symbol in the form of a diagonal [[cross]]. The word comes from the [[Middle French]] {{lang|frm|sautoir}}, [[Medieval Latin]] {{lang|la|saltatoria}} ("[[stirrup]]").<ref>Heraldic use 13th century (attested 1235, [[Huon de Méry]], ''Tournoiemenz Antecrist'', v. 654). In 1352 also of a particular form of stirrup (Comput. Steph. de la Fontaine argent, du Cange s.v. [http://ducange.enc.sorbonne.fr/SALTATORIA "saltatoria"]). 15th-century use in the sense of a barrier of wooden pegs arranged crosswise, preventing the passage of livestock that can still be ''jumped'' by people. "[http://stella.atilf.fr/Dendien/scripts/tlfiv5/advanced.exe?8;s=2623742685; sautoire]" in [[Trésor de la langue française|TLFi]]; see also [http://www.etymonline.com/index.php?term=saltire "saltire"] at [[Online Etymology Dictionary|etymonline.com]].</ref>

From its use as [[field sign]], the saltire came to be used in a number of flags, in the 16th century for [[Flag of Scotland|Scotland]] and [[Cross of Burgundy|Burgundy]], in the 18th century also as the ensign of the [[Ensign of the Russian Navy|Russian Navy]], and [[Saint Patrick's Saltire|for Ireland]]. Notable 19th-century usage includes some of the [[flags of the Confederate States of America]]. It is also used in the [[flag of Jamaica]] and on [[Seal (emblem)|seals]], and as a [[Charge (heraldry)|heraldic charge]] in [[Coat of arms|coats of arms]].

The term '''saltirewise''' or '''in saltire''' refers to heraldic charges arranged as a diagonal cross. The [[Escutcheon (heraldry)|shield]] may also be [[Division of the field|divided]] '''per saltire''', i.e. diagonally.

A warning sign in the shape of a saltire is also used to indicate the point at which a [[Level crossing|railway line intersects a road]] at a level crossing.

== Heraldry and vexillology ==
{{Further|Crosses in heraldry#Ordinary cross}}The saltire is important both in [[heraldry]], being found in many coats of arms, and in [[vexillology]], being found as the dominant feature of multiple flags.[[File:Ötingen ZW.png|thumb|upright|Coat of arms of the counts of [[Oettingen in Bayern|Ötingen (Oettingen)]]: Azure a bordure vair ancien gules and or, a saltire argent over all (attested from as early as 1180,<ref>Berhard Peter, [http://www.welt-der-wappen.de/Heraldik/oettingen.htm Die Wappen des Hauses Oettingen] (2010&ndash;2016).</ref> here in the depiction in the [[Zürich armorial]], {{Circa|1340}}).]]

The saltire is one of the so-called [[ordinary (heraldry)|ordinaries]], geometric [[Charge (heraldry)|charges]] that span throughout (from edge to edge of) the shield. As suggested by the name ''saltire'' ("stirrup"; in French: ''[[:wikt:sautoir#French|sautoir]]'', in German: ''[[:wikt:schräg#Etymology|Schragen]]''), the ordinary in its early use was not intended as representing a [[Christian cross]] symbol. The association with [[Saint Andrew]] is a development of the 15th to 16th centuries. The [[Cross of Burgundy]] emblem originates in the 15th century, as a field sign, and as the Saint Andrew's Cross of [[Flag of Scotland|Scotland]] was used in flags or banners (but not in coats of arms) from the 16th century, and used as [[naval ensign]] during the [[Age of Sail]].

When two or more saltires appear, they are usually [[blazon]]ed as [[Attitude (heraldry)|couped]] (cut off). For example, contrast the single saltire in the arms granted to G. M. W. Anderson{{efn|name=Anderson|''Or on a saltire engrailed Azure two quill pens in saltire Argent enfiling a Loyalist military coronet Or''<ref>{{cite web|url=http://archive.gg.ca/heraldry/pub-reg/project.asp?ProjectID=149&ShowAll=1 |title=Anderson, George Milton William [Individual&#93; |publisher=Archive.gg.ca |date=2005-07-28 |access-date=2012-09-09}}</ref>}}—with the three ''saltires couped'' in the coat of Kemble Greenwood.{{efn|name=Greenwood|''Sable a chevron Erminois cotised between three saltires couped Or''<ref>{{cite web|url=http://archive.gg.ca/heraldry/pub-reg/project.asp?ProjectID=240&ShowAll=1 |title=Greenwood, Kemble [Individual&#93; |publisher=Archive.gg.ca |date=2005-07-28 |access-date=2013-10-25}}</ref>}}

[[Ordinary (heraldry)#Diminutive of the saltire|Diminutive]] forms include the ''fillet saltire'',{{efn|name=Museum|The coat of the South African National Cultural and Open-air Museum: ''Or; an ogress charged with a fillet saltire surmounted by an eight spoked wheel or, and ensigned of a billet sable; a chief nowy gabled, Sable''}} usually considered half or less the width of the saltire, and the ''saltorel'', a narrow or couped saltire.

A field ''(party) per saltire'' is divided into four areas by a saltire-shaped "cut". If two [[Tincture (heraldry)|tinctures]] are specified, the first refers to the areas above (in chief) and below (in base) the crossing, and the second refers to the ones on either side (in the flanks).{{efn|name=Sandwell|The coat of the Sandwell Metropolitan Borough Council: ''Per saltire Vert and Or four Fers de Moline counterchanged in fess point a Fountain.''<ref>{{cite web|url=http://www.civicheraldry.co.uk/west_mid.html#sandwell%20mbc |title=Civic Heraldry Of England And Wales-West Midlands |publisher=Civicheraldry.co.uk |access-date=2012-09-09}}</ref> }} Otherwise, each of the four divisions may be blazoned separately.

The phrase ''in saltire'' or ''saltirewise'' is used in two ways:
# Two long narrow charges "in saltire" are placed to cross each other diagonally. Common forms include the crossed [[key (lock)|keys]] found in the arms of many entities associated with [[Saint Peter]] and paired arrows.{{efn|name=Suffolk|Suffolk County Council's ''Gules a Base barry wavy enarched Argent and Azure issuant therefrom a Sunburst in chief two Ancient Crowns enfiled by a pair of Arrows in saltire points downwards all Or''<ref>{{cite web |url=http://www.civicheraldry.co.uk/east_anglia_essex.html |title=Civic Heraldry Of England And Wales – East Anglia And Essex Area |publisher=Civicheraldry.co.uk |access-date=2012-09-09 |archive-date=2009-08-28 |archive-url=https://web.archive.org/web/20090828061517/http://www.civicheraldry.co.uk/east_anglia_essex.html |url-status=dead }}</ref>}}

Division of the field ''per saltire'' was notably used by the [[Crown of Aragon|Aragonese]] kings of [[Kingdom of Sicily|Sicily]] beginning in the 14th century ([[Frederick the Simple]]), showing the [[pales of Aragon]] and the "Hohenstaufen" eagle (argent an [[Reichsadler|eagle sable]]).

=== Scotland ===
[[File:Flag of Scotland.svg|thumb|left|upright|[[Flag of Scotland]]]]
The [[Flag of Scotland]], called ''The Saltire'' or ''Saint Andrew's Cross'', is a blue field with a white saltire. According to tradition, it represents [[Saint Andrew]], who is supposed to have been crucified on a cross of that form (called a ''crux decussata'') at [[Patras]], [[Greece]].

The Saint Andrew's Cross was worn as a badge on hats in Scotland, on the day of the [[Feast day|feast]] of Saint Andrew.{{ref label|1728|1|^}}

In the [[politics of Scotland]], both the [[Scottish National Party]] and [[Scottish Conservative Party]] use stylised saltires as their party logos, deriving from the flag of Scotland. Furthermore, the [[Scottish Government]] uses the flag as its official symbol on Scottish Government publications, including letters, documents and press releases. <ref>{{cite web |title=Scottish Government - Saltire Intranet |url=https://stormid.com/work/scottish-government-saltire-intranet |publisher=stormid |access-date=8 December 2023}}</ref>

Prior to the [[Acts of Union, 1707|Union]], the [[Royal Scots Navy]] used a [[red ensign]] incorporating the St Andrew's Cross; this ensign is now sometimes flown as part of an unofficial [[civil ensign]] in [[Scottish waters]]. With its colours exchanged (and a lighter blue), the same design forms part of the [[Coat of Arms of Nova Scotia|arms]] and [[flag of Nova Scotia]] (whose name means "New Scotland").

=== Cross of Burgundy ===
[[File:Cross of Burgundy (Template).svg|thumb|right|upright|[[Cross of Burgundy]]]]
The [[Cross of Burgundy]], a form of the Saint Andrew's Cross, is used in numerous flags across [[Europe]] and the [[Americas]]. It was first used in the 15th century as an emblem by the [[House of Valois-Burgundy|Valois Dukes of Burgundy]]. The [[Duchy of Burgundy]], forming a large part of eastern [[France]] and the [[Low Countries]], was inherited by the [[House of Habsburg]] on the extinction of the Valois ducal line. The emblem was therefore assumed by the monarchs of [[Spain]] as a consequence of the Habsburgs bringing together, in the early 16th century, their Burgundian inheritance with the other extensive possessions they inherited throughout [[Europe]] and the [[Americas]], including the crowns of [[Crown of Castile|Castile]] and [[Crown of Aragon|Aragon]]. As a result, the Cross of Burgundy has appeared in a wide variety of flags connected with territories formerly part of the Burgundian or Habsburg inheritance. Examples of such diversity include the Spanish naval ensign (1506-1701), the flag of [[Carlism]] (a nineteenth century Spanish conservative movement), the flag of the Dutch capital of [[Amsterdam]] and municipality of [[Eijsden]], the flag of [[Chuquisaca Department|Chuquisaca]] in Bolivia and the flags of [[Florida]] and [[Alabama]] in the United States.

=== Gascony ===
[[File:Gascogne drapeau.svg|thumb|left|upright|[[Flag of Gascony]] <br />{{lang|oc|Lo Sautèr}} ('the Saltire')]]
[[Gascony]] has not had any institutional unity since the 11th century, hence [[Gascony#Flags|several flags]] are currently used in the territory. Legend says that this flag appeared in the time of [[Pope Clement III]] to gather the Gascons during the [[Third Crusade]] (12th century). That flag, sometimes called "Union Gascona" (Gascon Union), contains the [[St Andrew]]'s cross, the patron saint of [[Bordeaux]] and the red color of [[English kingdom]], which reigned over [[Gascony]] from 12th to mid-15th century.
In Tome 14 of the [[La Grande Encyclopédie|Grande Encyclopédie]], published in France between 1886 and 1902 by [[Henri Lamirault]], it says {{Quote|during the hard times of the Hundred Years' War and the terrible struggles between the [[Armagnac (party)|Armagnacs]], representing the national party (white cross) and the [[Burgundian (party)|Burgundians]], allied to the English (red cross and red Saint Andrew's cross), the flag of the victorious English ends up gathering, in 1422, under [[Henry VI of England|Henri VI]], on its field the white and red crosses of France and England, the white and red Saint Andrew's crosses of [[Guyenne]] and [[Burgundy]].<ref name="gallica">{{Cite book|url=https://gallica.bnf.fr/ark:/12148/bpt6k24649b/f1071.item|title=La grande encyclopédie : Inventaire raisonné des sciences, des lettres et des arts.

That saltire is also represented in the pattern of some {{lang|oc|talenquères}} in many [[bullring]]s in Gascony.<ref>{{cite tweet|number=701400643932545024|user=Pickwicq|title=Amandine derrière la talenquère pour pentecôte à Samadet 2015<!-- full text of tweet that Twitter returned to the bot (excluding links) added by TweetCiteBot.

=== Maritime flags ===
[[File:Naval Ensign of Russia.svg|thumb|right|upright|[[Russian Navy Ensign|St Andrew's flag]], used by the Russian Navy]]
The naval [[Maritime flags|ensign]] of the [[Imperial Russian Navy|Imperial Russian]] (1696–1917) and [[Russian Navy|Russian]] navies (1991–present) is a blue saltire on a white field.

The [[international maritime signal flag]] for ''M'' is a white saltire on a blue background, and indicates a stopped vessel. A red saltire on a white background denotes the letter ''V'' and the message "I require assistance".

=== Others ===
The flags of the Colombian archipelago of [[San Andrés and Providencia Department|San Andrés and Providencia]] and the Spanish island of [[Flag of Tenerife|Tenerife]] also use a white saltire on a blue field. The Brazilian cities of [[Rio de Janeiro]] and [[Fortaleza]] also use a blue saltire on a white field, with their coats-of-arms at the hub.

Saltires are also seen in several other flags, including the flags of [[Flag of Grenada|Grenada]], [[Flag of Jamaica|Jamaica]], [[Flag of Alabama|Alabama]], [[Flag of Florida|Florida]], [[Flag of Jersey|Jersey]], [[Logroño]], [[Vitoria-Gasteiz|Vitoria]], [[Flag of Amsterdam|Amsterdam]], [[Breda]], [[Katwijk]], [[Potchefstroom]], [[Bandera del Bierzo|The Bierzo]] and [[flag of Valdivia|Valdivia]], as well as the former Indian [[princely state]]s of [[Khairpur (princely state)|Khairpur]], [[Rajkot State|Rajkot]] and [[Jaora State|Jaora]].

The design is also part of the [[Confederate Battle Flag]] and [[Flags of the Confederate States of America#Naval flags|Naval Jack]] used during the [[American Civil War]] (see [[Flags of the Confederate States of America]]). Arthur L. Rogers, designer of the final version of the Confederate National flag, claimed that it was based on the saltire of Scotland.<ref>{{cite book|last=Coski|first=John M.|title=The Confederate Battle Flag: America's Most Embattled Emblem|url=https://books.google.com/books?id=zs0VJTbNwfAC|year=2005|location=United States of America|publisher=First Harvard University Press|isbn=978-0-674-01722-1|pages=17–18}}</ref> The saltire is used on modern-day Southern U.S. state flags to honour the former Confederacy.<ref>{{cite book|last=Coski|first=John M.|title=The Confederate Battle Flag: America's Most Embattled Emblem|url=https://books.google.com/books?id=zs0VJTbNwfAC|year=2005|location=United States of America|publisher=First Harvard University Press|isbn=978-0-674-01722-1|page=79}}</ref>

== Christian symbol ==
Anne Roes (1937) identifies a design consisting of two crossing diagonal lines in a rectangle, sometimes with four dots or balls in the four quarters, as an emblem or ''vexillum'' (standard) of [[Persepolis]] during the 3rd to 2nd centuries BC. Roes also finds the design in [[Argive vase painting]], and still earlier in button seals of the Iranian Chalcolithic. Roes also notes the occurrence of a very similar if not identical ''vexillum'' which repeatedly occurs in [[Gaulish coin]]s of c. the 2nd to 1st century BC, in a recurring design where it is held by a charioteer in front of his human-headed horse.<ref>Roes (1937), footnote 15, citing Henri de La Tour, '' Atlas de monnaies gauloises'' (1892), plates [https://gallica.bnf.fr/ark:/12148/bpt6k8803676/f65.item.zoom xxi], [https://gallica.bnf.fr/ark:/12148/bpt6k8803676/f69.item.zoom xxiii], coins of the [[Diablintes|Aulerci Diablintes]], [[Aulerci Cenomani]] and [[Osismii]].</ref> A large number of coins of this type (118 out of 152 items) forms part of the Les Sablons hoard of the 1st century BC, discovered in [[Le Mans]] between 1991 and 1997, associated with the [[Aulerci Cenomani|Cenomani]].<ref>''Trésors monétaires'', volume XXIV, BNF, 2011.</ref>
 
The same design is found on coins of Christian Roman emperors of the 4th to 5th centuries ([[Constantius II]], [[Valentinian III|Valentinian]], [[Jovian (Emperor)|Jovian]], [[Gratianus]], [[Valens]], [[Arcadius]], [[Constantine III (western emperor)|Constantine III]], [[Jovinus]], [[Theodosius I]], [[Eugenius]] and [[Theodosius II]]). The letter [[Chi (letter)|Χ (Chi)]] was from an early time used as a symbol for Christ (unrelated to the [[Christian cross]] symbol, which at the time was given a [[Tau cross|T-shape]]). The ''vexillum'' on imperial coins from the 4th century was sometimes shown as the [[Labarum]], surmounted by or displaying the [[Chi-Rho]] monogram rather than just the ''crux decussata''. The emblem of the ''crux decussata'' in a rectangle, sometimes with four dots or balls, re-appears in coins the [[Byzantine Empire]], in the 9th to 10th centuries. Roes suggested that early Christians endorsed its [[solar symbol]]ism as appropriate to [[Christ]].<ref name=":0">{{cite journal |first=Anne |last=Roes |title=An Iranian standard used as a Christian symbol |journal=The Journal of Hellenic Studies |volume=57 |issue=2 |year=1937 |pages=248–51 |doi=10.2307/627151 |jstor=627151 |s2cid=162699148 }}</ref>

The association with [[Saint Andrew]] develops in the late medieval period. The tradition according to which this saint was crucified on a decussate cross is not found in early hagiography. Depictions of Saint Andrew being crucified in this manner first appear in the 10th century, but do not become standard before the 17th century.<ref>Cudith Calvert, "The Iconography of the St. Andrew Auckland Cross", The Art Bulletin 66.4 (December 1984:543–555) p. 545, note 12, citing [[Louis Réau]], Iconographie de l'art chrétien III.1 (Paris) 1958:79.</ref> Reference to the saltire as "St Andrew's Cross" is made by the [[Parliament of Scotland]] (where Andrew had been adopted as [[patron saint]]) in 1385, in a decree to the effect that every Scottish and French soldier (fighting against the [[English invasion of Scotland (1385)|English under Richard II]]) "shall have a sign before and behind, namely a white St. Andrew's Cross".<ref>The Records of the Parliaments of Scotland to 1707, K.M.

[[File:Hazard X.svg|thumb|upright=0.56|Chemical hazard]]
The diagonal cross (decussate cross) or [[X mark]] is called "saltire" in heraldic and vexillological contexts.

A black diagonal cross was used in an old European Union standard as the hazard symbol for irritants (Xi) or harmful chemicals (Xn). It indicated a hazard less severe than [[skull and crossbones (poison)|skull and crossbones]], used for [[poison]]s, or the [[corrosive]] sign.

The [[Maria Theresa thaler]] has a [[Roman numeral]] ten to symbolize the 1750 debasement of the coinage, from 9 to 10 thalers to the Vienna mark (a weight of silver).

A diagonal cross known as "[[crossbuck]]" is used as the conventional [[road sign]] used to indicate the point at which a railway line intersects a road at a [[level crossing]]. A white diagonal cross on a blue background (or black on yellow for temporary signs) is displayed in [[UK railway signalling]] as a "cancelling indicator" for the [[Automatic Warning System]] (AWS), informing the driver that the received warning can be disregarded.

In [[Cameroon]], a red "X" placed on illegally constructed buildings scheduled for demolition is occasionally referred to as a "St Andrew's Cross". It is usually accompanied by the letters "A.D." ("à détruire"—French for "to be demolished") and a date or deadline. During a campaign of urban renewal by the [[Yaoundé]] Urban Council in Cameroon, the cross was popularly referred to as "Tsimi's Cross" after the Government Delegate to the council, Gilbert Tsimi Evouna.<ref>{{Cite web|url=http://www.lemessager.net/details_articles.php?code=118&code_art=24911|archiveurl=https://web.archive.org/web/20081217101704/http://www.lemessager.net/details_articles.php?code=118&code_art=24911|url-status=dead|title=Célestin Obama.
