Seals
In ancient times, documents were authenticated by means of a seal that
made an impression in clay or wax. The custom of signing a document
with an autograph began during the Middle Ages, and by the close of the
period, seals were used only in some offi cial capacities, such as customs or
government certifi cates. Through most of the Middle Ages, though, seals
were the most common means of authenticating a document, perhaps ac-
companied by a cross and the person’s name. Unlike the crudely stamped
coins of the time, seals could make a fi ne, detailed impression. They carried
the owner’s name and a design similar to a coat of arms. In some cases, the
seal needed to have a date on it, so it carried letters around the rim specify-
ing the year of the king’s reign.
Although at fi rst only kings had seals, by the 13th century, anyone who
wanted to sign a document needed a personal seal. Anyone who entered a
contract, bought or leased land, made treaties, or made proclamations had to
own a seal. Monasteries and bishops had seals, as did companies, guilds, and
every aristocrat. Kings had personal seals, and their households and depart-
ments (exchequer, navy, army, customs) had seals for conducting business.
Judges, courts, towns, and counties had seals. When poor people needed to
sign a contract but did not own a seal, they had to impress a key instead.
Aristocrats’ seals had their heraldic arms as well as some personal mark-
ing, including their name. Guilds and tradesmen used symbols of their craft,
while bishops and monasteries used religious symbols. People who did not
have a right to heraldry used designs with animals, birds, hearts, letters,
and mottoes. In a late medieval city, seal makers sold generic (but unique)
seals for common people, and they cast seals with a few ready-made design
elements that could be engraved with personal details for a particular cus-
tomer. If a seal was lost, unauthorized parties could use it for forging. The
owner had to get a new one made immediately.
Seals were usually made of metal, most often brass or bronze. Royal
ones were often gold, and common ones used for business were base met-
als such as pewter. They could also be carved from ivory, jet, or even soap-
stone. Signet rings were not often used until the 15th century, although
King Richard the Lionheart had one. Then, the design could be cut into
