Heraldry has its own technical language in English, with its own names for all sorts of things. (For example, the color red is called "gules"; a 5-pointed star is called a "mullet", and so on.) The exact English heraldic equivalent of the Spanish heraldic cartela is a "billet". That being said, you will not find one person in a thousand who knows what a heraldic "billet" is. Nevertheless, you might translate this as "Even today, in the arches one can see shields charged with billets." https://forum.wordreference.com/threads/cartela-heraldica.14...


The billet is a rectangle, usually at least twice as tall as it is wide; it may represent a block of wood or a sheet of paper. Billets appear in the shield of the house of Nassau, which was modified to become that of the kingdom of the Netherlands. The roundel is a solid circle, frequently of gold (blazoned a bezant).

Superimposed on the field are the charges. The most common charges are called ordinaries, basic geometric bands of color such as the fess (a horizontal band across the central third of the field), the chief (a band across the top), the pale (a vertical band down the central third), the bend (a wide diagonal band), the bar (a horizontal band one-fifth the depth of the shield), and the chevron (an inverted V). Also called ordinaries -- or by some experts, subordinaries -- are such less-common shapes as the cross, the saltire (a diagonal cross), the pile (a triangular wedge from the top), ****the billet (a small rectangle)****, the bordure (a narrow border), the orle (a border set in from the edge), and the inescutcheon (an inner shieldlike shape), among many others. Many of these charges appear in multiple and diminutive form, in which case they are called barry, bendy, paly, or by the appropriate plural form.
