A saltorel is a narrow saltire; the term is usually defined as one-half the width of the saltire, and is a relatively recent "innovation". This is apparently different from a fillet saltire.
A field that is party per saltire is divided into four areas by x-shaped cuts. If two tinctures are specified, the first refers to the areas above and below the X, and the second refers to the ones on either side. Otherwise, each of the four divisions may be blazoned separately, the sequence being then top, left, right, bottom.
The phrase in saltire is used in two ways: to describe two charges, such as the keys in the arms of many entities associated with Saint Peter, crossing each other diagonally; or for five or more charges, one in the center and one or more on each arm of an invisible saltire.
Three saltires couped appear in the arms and flag of Amsterdam, and a saltire is used by a supporter of the royal arms of Scotland. The Image:Saint Alban's cross.svg to the Kingdom of Mercia was a gold saltire on a light blue background. Thus, Azure a saltire Or are now the arms of the City and District of St Albans.
The Flag of Scotland, called The Saltire or St 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. The St Andrew's Cross was worn as a badge on hats in Scotland, on the day of the feast of St Andrew. It is the oldest continuously used sovereign flag in the world, having been in use since AD 832 - or so legend has it.
Numerous flags are inspired by the saltire and the colours blue and white—mostly connected with Scotland or Russia, where Saint Andrew is the national patron saint. The naval ensign of the Imperial Russian (1696-1917) and Russian navies (1991-present) is a blue saltire on a white field. Prior to the 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. The blue saltire on white design is featured on the Coat of Arms of Nova Scotia, Canada and its flag (Nova Scotia was originally a Scottish colony), but the blue used for Nova Scotia is generally a light blue. Similarly, the flags of the Spanish island of Tenerife and the remote Colombian islands of San Andrés and Providencia also use a white saltire on a blue field.
The Flag of Scotland forms one of the three crosses that are superimposed to form the Union Flag of the United Kingdom of Great Britain and Northern Ireland. (The other two are St George's Cross [representing England and Wales] and St Patrick's Cross [representing Ireland].)
Saltires are also seen in several other flags, including the flags of Grenada, Jamaica, Alabama, Florida, Jersey, Amsterdam, Potchefstroom and Valdivia. The design is also part of the Confederate Battle Flag and Naval Jack used during the American Civil War (see Flags of the Confederate States of America). William Porcher Miles, designer of the Confederate Battle Flag never claimed it to be a St. Andrew's cross design, but rather a heraldic saltire without religious symbolism.
A white saltire 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 or 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 Yaounde Urban Council in Cameroon, the cross was popularly referred to as "Tsimi's Cross" after the Government Delegate to Yaounde Urban Council Gilbert Tsimi Evouna.
