The Origins of Heraldry part 6

Next to the enamel we have the evidence of the seals, which in the period from 1135 to 1155 show the use of heraldic designs. Seals were used not only in the Middle ages but much earlier to authenticate documents for those that could not read. In ages when few were literate there had to be some sign that men could easily understand to show that the person who was supposed to have produced the document had actually done so. The seal which was attached to the document had to have something that identified the user of the seal. There is evidence of the use of seals as early as the Babylonian and Assyrian empires, and the practice was brought to Europe long before writing became commonplace. Thus though we often speak of King John having signed the Magna Carta in 1215, what we really mean is that he sealed it, for it is his seal and not his signature which is shown on the document. Apart from the enamels I quoted earlier from 1136 the seals of arms constitute our earliest physical evidence of the appearance of coats of arms.
