Patterns derived from animal fur such as veils and ermines

The pattern originated from fur clothing, which was a symbol of authority for the ruling class.

In medieval Western Europe, fur became widely used as a symbol of authority for the ruling class.

Naturally, at first it was primarily used as cold weather clothing, but depending on the materials and how it was used, such as using only rare fur such as the white hair from the belly of a squirrel as lining for textiles, fur products began to become luxury items owned by the wealthy.

The veil and ermine are patterns made from fur

You may have seen portraits of medieval aristocrats in Western portraits wearing luxurious furs, and some of that fur was dyed in various patterns, and these patterns were sometimes used as coats of arms.

They are ermine, which has a continuous bell-shaped pattern called a veil, or is derived from the black tail of a mustelid such as an ermine.
