When the term "cross" appears in a blazon and no type is specified, it refers to an ordinary made up of two lines, one horizontal and one vertical, that overlap at the center of the field. Like most other ordinaries, a cross can can use complex lines. It can be divided into two or more tinctures. It can be be fimbriated, voided, or cotised. Other charges can be placed on it, or it can overlie other charges. There are no special rules for blazoning these particulars; it works the same way it works for any other ordinary.
A cross, like a fess, a saltire, or a chevron, can be also be couped. That is, the ends of the arms can be cut short, so that they don't reach the edges of the shield. Such crosses are simple variants of the ordinary.
Where things really begin to get complicated is in the plethora of specialty crosses that were recognized in period heraldry as independent charges, the smaller but significant number of modern crosses inspired by these or by period motifs or artifacts that are part of S.C.A. heraldry, and all the optional treatments that can be used to distinguish crosses of the same types from one another. Add in the fact that the characteristics of certain types of crosses can be combined, with or without additional treatments, to create doubly- and triply-complex variants, and dealing with crosses as a category quickly becomes one of the most befuddling aspects of heraldry in the Society.
To simplify the conflict-checking process, the sovereigns at arms have grouped a number of the most common period cross types into "famillies" . Any cross included in one of these families is considered to be substantially changed (as defined in Part A.5 of the S.C.A's Standards for Evaluation of Names and Armory) from any cross in any other family. But not every sort of cross that can be registered is included in this list, and not every pair of types that are substantially changed from one another is represented. Crosses that aren't part of any family must be compared one-to-one with each other and with family crosses when conflict checks are done. Comparisons that have been weighed by the sovereigns at arms in the past are mentioned in the precedents, but there are plenty of types of cross that they've never had reason to constrast with one another.
The sovereigns at arms have established a few general principles that can be applied when crosses are checked for conflict.
"Standard period variants of a particular style of cross will not be considered separate; no difference is granted for fitching, changing between equal-armed and Latinate, etc." (cover letter to the May, 2009 LoAR)
"While we give a CD for a standard cross throughout versus a cross couped, for most crosses. . .we do not give such difference for couped versus throughout." (February, 2002 LoAR) [There are some exceptions.]
"Adding or removing a. . .tertiary. . .charge group is a distinct change (DC)." (SENA Part A.5.G.2) [A tertiary charge group is any group of charges placed entirely on other charges, which includes charges on crosses.]
And there are some general rules about crosses and period style, including these:
"A cross of any type should either be throughout on all arms or not throughout on any of them." (July, 2004 LoAR)
"The default crusilly is of crosses crosslet." (August, 2002 LoAR) ["Crusilly" means "semy of crosses"—that is, 'having multiple crosses scattered over it.']
"While SCA-variant charges are often considered acceptable ('period-compatible', as it were), we draw the line at variants of SCA-variants." (November, 1992 LoAR)
"The SCA allows crosses of all sorts to be charged. . .." (April, 2002 LoAR)
"A cross throughout which overlies the line of division on a quarterly field does not remove the appearance of marshalling by quartering, even if the cross throughout is treated with a complex line (such as engrailed) or has complex ends (such as formy or moline.) A cross which is not throughout, or which does not overlie the quarterly line of division (such as a Tau cross), will remove the appearance of marshalling unless evidence is presented that the cross under discussion was used for marshalling in period heraldry." (June, 2003 LoAR)
Because, "It is poor style to use two similar but non-identical charges in a single group," the use of two different types of crosses in a single charge group is grounds for return. (July, 1991 LoAR, June, 1995 LoAR)
"[A]ny non-ordinary cross used as a charge, is not an ordinary and thus cannot be counterchanged over an ordinary. . .." (May, 2006 LoAR)
On a tower or castle, "Cross that appear to be arrow slits, such as plain crosses and crosses pometty, will be treated as architectural details - not as tertiary charges," (January, 2008 LoAR), and "artistic details are allowed to have poor contrast," (November, 2009 LoAR).
These broad ideas, combined with the precedents related to specific cross types that I've collected in the tables that make up the bulk of this article, should help anyone who's considering submitting armory that contains one or more crosses get a head start on researching any issues with them that are likely to arise. Use the lists below to navigate directly to information on a cross type that interests you, or browse through the images on the table pages if you aren't sure what the cross you're considering is called.
Note: I've tried to index every term that appears in a registered blazon or precedent, so that someone looking for more information on one can easily find it. That means that some types of crosses are listed more than once, under different terms that have been used to describe them. So if you click on one term and find yourself routed to a table entry headed with another, read the entry. Odds are the term you're investigating is an alternate blazon.
