The art and science of designing flags (also called vexillography) owes much of its imagery and traditions to the much older craft of heraldry. For centuries, heraldic colors, objects, patterns, animals, and shapes have allowed people to share their heritage and accomplishments through a common artistic language rich with symbolism and meaning. All kinds of groups and organizations use heraldry, from families to cities to countries to colleges. Here are some of the coats of arms based on heraldic traditions that are still used today.
