History of heraldry in Ireland
Heraldry is the study and description of coats of arms, and of the rights of
individuals and families to bear arms. It began in the first half of the twelfth
century, as a result of developments in medieval weaponry and armour in
continental Europe. The old coats of chain-and-link mail, with long shields, gave
way to full-body plate armour and helmets encasing the entire head, with smaller
triangular shields. Individual knights thus became completely anonymous. The
necessity for markings on their shields to identify themselves in battles and in
tournaments is self-evident.
At first, this military necessity was the determining factor. Large, clearly
identifiable patterns, involving two or three colours divided into a number of
compartments related to the physical construction of the shield make up the
earliest arms. Later, when animals and other symbols were added, the
necessity for easy, quick recognition again meant that a large degree of stylised
convention was used, so that the heraldic lion, for instance, bears only a slight
resemblance to the real thing.
The military origin of arms is also the most likely explanation for their emergence
at almost exactly the same time in England, France, Germany and Italy. The
eight Christian crusades against Islam between 1096 and 1271 involved knights
from all of these countries, and, combined with the changes in armour, provided
a context in which a system of military recognition was essential. The
endurance of heraldry is no doubt partly due to the fact that it spread over the
whole of Europe virtually simultaneously. Crosses and fleurs-de-lis, Christian
symbols par excellence, also take their origins in heraldry from the Crusades.
But heraldry would long ago have died out completely if the only need it met was
military. Individual recognition and family identity powerful and universal human
needs. And towards the end of the thirteenth century, a further change came
about as the social and non-military aspects of heraldry evolved and it was
established that coats of arms were personal and hereditary. The symbols used
could now relate to the name, the office or the territory of the bearer, and were
dictated less by the imperative of immediate recognition. One of the results from
this period on was the creation of so-called "canting" arms, based on a pun on
the name - in Ireland, the arms of the Aherne family, displaying three herons, are
an example. The main non-military use of arms was on seals, as a means of
proving the authenticity of documents, and the practice of using birds or animals
to fill empty space around the arms on these seals gave rise to "supporters",
now regarded as part of the arms of peers. Eventually, arms were also used on
tombs, and then on works of art and possessions.
The symbols used in heraldry have a variety of origins: in the Christian nature of
the crusades, in the (supposed) character of the individual or family itself, in
some event which is identified with the family. There is no strict attachment of
significance to particular symbols, although the reasons for some symbols are
self-evident; the lion is conventionally regal, the unicorn is a symbol of purity, the
boar is a Celtic symbol of endurance and courage, and so on.
As arms proliferated, a natural need arose for rules to prevent different individuals
and families using the same or similar symbols and arrangements of symbols.
The first result was the evolution of the peculiar technical vocabulary used in
describing arms, a highly stylised and extremely precise mixture of early
French, Latin and English, still used in heraldry today. Then came the creation
of the offices of King of Arms or King of Heralds throughout most of Europe in
the fourteenth century. The principal functions of these were the recognition of
arms, the recording of the possession of arms, the granting of arms and
adjudication in disputes between bearers of arms. By the end of the fifteenth
century, since the right to bear arms depended on family and ancestry, they had
also become genealogists.
