The “cross couped”, technically speaking, is simply a cross with its ends cut, so that it is not throughout; but it’s conventionally rendered with arms of equal length (cf. the discussion on the cross humetty). The usage is found as early as c.1255, in the arms of Sarren [ANA2 349]. The cross couped in the illustration, with arms as wide as they are long, may also be called a “Greek cross”. Note that the use of a red cross couped on a white background, by itself or in combination with other motifs, has been restricted due to its use as the symbol of the International Red Cross, which is protected by mundane international law.

Brant Marcksson bears: Per bend sinister argent and vair, in dexter chief a cross couped vert.
The “Coptic cross” is a motif found in Christian art in Ethiopia and Egypt. The term has been applied in modern times to several cross motifs; the illustrated form is the one accepted for Society use. It has not been found in mundane heraldry.

The “cross of Coldharbour” was a Society invention when it was first registered; it has since been deemed equivalent to (and blazoned as) a “Celtic cross throughout”. Since it is of the “gunsight” depiction of the Celtic cross, it is no longer permitted.
Henry of Coldharbour bears: Argent, a cross of Coldharbour gules.
The “cross clechy” was originally a variant form of the crosses formy and patonce: it was blazoned a crux florida patens in the Boke of St. Albans, 1485, and used in the arms of da Lisson, mid-15th Century [Triv 201]. Modern heraldry texts sometimes blazon it as a “cross urdy”; in Society blazonry, the latter term is reserved for the cross as an ordinary with a complex line of division.
Teleri Tawel bears: Sable, in chief three crosses clechy Or.
Antonio Giovanni Pecoraro bears: Per pale and per chevron argent and azure, three crosses clechy counterchanged.
The “cross of Cerdaña” is a Society invention; it’s essentially a square set on one corner, with a semi-circular notch in each side. This cross has been disallowed for Society use.
Rodrigo de Cerdaña bears: Or, a cross of Cerdaña gules, a chief embattled arrondi azure.
The “Celtic cross” is found in Irish stone sculptures, dating from the 5th Century; it’s characterized by a thin annulet conjoined to the limbs, which are broad and either straight or slightly tapered, extending beyond the annulet. The most common form of Celtic cross in the Society is Latinate, with an elongated lower limb, but an equal-armed variant is also found. These remain registerable as “Celtic crosses”.
In the past, the Society has also registered an “equal-armed Celtic cross” that was effectively a cross potent surmounted by an annulet; this form mimics a cross found in period heraldry, the arms of Cardinal St. Marie, 1413 [Conz.Const. lxxi], but with the annulet interlacing the cross potent. The latter remains registerable, but now is blazoned explicitly as a “cross potent interlaced with an annulet” and treated as two charges. The heraldic difference between all these forms of Celtic cross is negligible.
Celtic crosses made by adding an annulet to another type of cross (e.g., a “Celtic cross moline”) are considered a step from period practice as of this writing. Modern depictions of the Celtic cross, where the annulet and cross are thin lines of equal width (like a gunsight) are not permitted.

The “cross of Canterbury” was first found as a piece of jewelry, dating from the 8th or 9th Century, excavated in 1867 in St. George’s Street, Canterbury (and now in the Royal Museum). The design was later carved into the wall of Canterbury Cathedral (SW Transept). It is the symbol of that religious house.
Sebastian de Grey bears: Purpure, an owl close affronty and on a chief argent three crosses of Canterbury purpure.

The “cross of Calvary” is a Latin cross mounted on a stepped pedestal; there are three steps (called “grieces” or “degrees”) by default. If more than three grieces are used, they must be explicitly numbered. The cross of Calvary is shown in rolls temp. Edward I, as the attributed canting arms of the King of Greece [ANA2 320]. In later period, other cross variants besides Latin crosses were shown atop grieces: Society heralds would blazon these as a “[variant] cross Calvary.” Thus Brytton, c.1460, bore what we would blazon a “Patriarchal cross Calvary” [RH]; Gloch, 1605, bore a “Tau cross potent Calvary” [Siebmacher 62]; while Iones, 1610, bore a “cross crosslet Calvary” [Guillim1 212].
Arthur of Ballonesmore bears: Per bend sinister purpure and argent, two crosses of Calvary and a bordure counterchanged.
The “cross of Calatrava” is also called the “cross of Aviz”; it was the insignia of the Knights of Calatrava, an Iberian order founded in 1158 [Spada’s Onori e Glorie: Sovrano Militare Ordine, p.59]. It was originally a highly ornamental form of the cross flory.
