, clay, paper, or some other medium, including an embossment on paper, and is also the impression thus made. The original purpose was to authenticate a document, or to prevent interference with a package or envelope by applying a seal which had to be broken to open the container (hence the modern English verb "to seal", which implies secure closing without an actual wax seal).
The seal-making device is also referred to as the seal ''matrix'' or ''die''; the imprint it creates as the seal impression (or, more rarely, the ''sealing''). If the impression is made purely as a relief resulting from the greater pressure on the paper where the high parts of the matrix touch, the seal is known as a ''dry seal''; in other cases ink or another liquid or liquefied medium is used, in another color than the paper.
In most traditional forms of dry seal the design on the seal matrix is in
intaglio (cut below the flat surface) and therefore the design on the impressions made is in
relief
Relief is a sculptural method in which the sculpted pieces are bonded to a solid background of the same material. The term ''relief'' is from the Latin verb ''relevo'', to raise. To create a sculpture in relief is to give the impression that the ...

The design on the impression will reverse (be a mirror-image of) that of the matrix, which is especially important when script is included in the design, as it very often is. This will not be the case if paper is embossed from behind, where the matrix and impression read the same way, and both matrix and impression are in relief. However

cameo in this context, giving a "counter-relief" or intaglio impression when used as seals. The process is essentially that of a
mould.
Most seals have always given a single impression on an essentially flat surface, but in medieval Europe two-sided seals with two matrices were often used by institutions or rulers (such as towns, bishops and kings) to make two-sided or fully three-dimensional impressions in wax, with a "tag", a piece of ribbon or strip of

in East Asia. Like ink-brush calligraphy, there are several styles of engraving. Some engraving styles emulate calligraphy styles, but many styles are so highly stylized that the characters represented on the seal are difficult for untrained readers to identify. Seal engravers are considered artists, and, in the past, several famous calligraphers also became famous as engravers. Some seals, carved by famous engravers, or owned by famous artists or political leaders, have become valuable as historical works of art.
Because seals are commissioned by individuals and carved by artists, every seal is unique, and engravers often personalize the seals that they create. The materials of seals and the styles of the engraving are typically matched to the personalities of the owners. Seals can be traditional or modern, or conservative or expressive. Seals are sometimes carved with the owners'
zodiac animals on the tops of the seals. Seals are also sometimes carved with images or calligraphy on the sides.

Wax seals were being used on a fairly regular basis by most western royal chanceries by about the end of the 10th century. In England, few wax seals have survived of earlier date than the Norman Conquest,[ although some earlier matrices are known, recovered from archaeological contexts: the earliest is a gold double-sided matrix found near Postwick, Norfolk, and dated to the late 7th century; the next oldest is a mid-9th-century matrix of a Bishop Ethilwald (probably Æthelwold, Bishop of East Anglia). The practice of sealing in wax gradually moved down the social hierarchy from monarchs and bishops to great magnates, to petty knights by the end of the 12th century, and to ordinary freemen by the middle of the 13th century. They also came to be used by a variety of corporate bodies, including ]cathedral chapter

In Central and Eastern Europe, however, as in East Asia, a signature alone is considered insufficient to authenticate a document of any kind in business, and all managers, as well as many book-keepers and other employees, have personal seals, normally just containing text, with their name and their position. These are applied to all letters, invoices issued, and similar documents. In Europe these are today plastic self-inking stamps.

'') to provide extra strength. Alternatively, the seal may be attached to a narrow strip of the material of the document (again, in this case, usually parchment), sliced and folded down, as a tail or ''tongue'', but not detached. The object in all cases is to help ensure authenticity by maintaining the integrity of the relationship between document and seal, and to prevent the seal's reuse. If a forger tries to remove an applied seal from its document, it will almost certainly break. A pendent seal is easily detached by cutting the cords or strips of parchment, but the forger would then have great difficulty in attaching it to another document (not least because the cords or parchment are normally knotted inside the seal), and would again almost certainly break it.
In the Middle Ages, the majority of seals were pendent. They were attached both to legal instrument

In the Middle Ages it became customary for the seals of women and of ecclesiastics to be given a vesica (pointed oval) shape. The central emblem was often a standing figure of the owner, or (in the case of ecclesiastical seals) of a saint.

was naturally yellowish or pale brownish in tone, but could also be artificially colored red or green (with many intermediary variations). In some medieval royal chanceries, different colours of wax were customarily used for different functions or departments of state, or to distinguish grants and decrees made in perpetuity from more ephemeral documents.
The matrices for pendent seals were sometimes accompanied by a smaller ''counter-seal'', which would be used to impress a small emblem on the reverse of the impression. In some cases the seal and counter-seal would be kept by two different individuals, in order to provide an element of double-checking to the process of authentication. Sometimes, a large official seal, which might be in the custody of chancery officials, would need to be counter-sealed by the individual in whose name it had been applied (the monarch, or the mayor of a town): such a counter-seal might be carried on the person (perhaps secured by a chain or cord), or later, take the form of a signet ring, and so would be necessarily smaller. Other pendent seals were double-sided, with elaborate and equally-sized obverses and reverses. The impression would be formed by pressing a "sandwich" of matrices and wax firmly together by means of rollers or, later, a lever-press or a screw press
A screw press is a type of machine press in which the ram is driven up and down by a screw. The screw shaft can be driven by a handle or a wheel. It works by using a coarse screw to convert the rotation of the handle or drive-wheel into a small d ...
. Certain medieval seals were more complex still, involving two levels of impression on each side of the wax which would be used to create a scene of three-dimensional depth.
On the death of a seal-holder, as a sign of continuity, a son and heir might commission a new seal employing the same symbols and design-elements as those used by his father. It is likely that this practice was a factor in the emergence of hereditary heraldry

In some jurisdictions, especially in Canada, it is a legal requirement for a professional engineer to seal documents in accordance with the Engineering Profession Act and Regulations. Professional engineers may also be legally entitled to seal any document they prepare. The seal identifies work performed by, or under the direct supervision of, a licensed professional engineer, and assures the document's recipient that the work meets the standards expected of experienced professionals who take personal responsibility for their judgments and decisions.

The practice is less widely attested in the case of medieval laypeople, but certainly occurred on occasion, particularly in the 13th and 14th centuries. Silver seal matrices have been found in the graves of some of the 12th-century queens of France. These were probably deliberately buried as a means of cancelling them.

Signet rings
A signet ring is a ring bearing on its flat top surface the equivalent of a seal. A typical signet ring has a design, often a family or personal Crest (heraldry), crest, created in intaglio (jewellery), intaglio so that it will leave a raised (relief

Sealing wax is a wax material of a seal which, after melting, hardens quickly (to paper, parchment, ribbons and wire, and other material) forming a bond that is difficult to separate without noticeable tampering. Wax is used to verify something su ...
. The design is often made out of agate, carnelian, or sardonyx which tend not to bind with the wax. Most smaller classical engraved gems were probably originally worn as signet rings, or as seals on a necklace.
The wearing of signet rings (from Latin "signum" meaning "sign" or "mark") dates back to ancient Egypt: the seal of a pharaoh is mentioned in the Book of Genesis. Genesis 41:42: "Removing his signet ring from his hand, Pharaoh put it on Joseph (Genesis), Joseph's hand; he arrayed him in garments of fine linen, and put a gold chain around his neck."
Because it is used to attest to the authority of its bearer, the ring has also been seen as a symbol of power, which is why it is included in the regalia of certain monarchies. After the death of a Pope, the destruction of his signet ring is a prescribed act clearing the way for the Sede vacante#Vacancy of the Holy See, ''sede vacante'' and subsequent election of a new Pope.
Signet rings are also used as souvenir or membership attribute, e.g., class ring (typically bear the coat of arms or crest of the school), as an alternative to one with a stone. One may also have their initials engraved as a sign of their personal stature.
The less noble classes began wearing and using signet rings as early as the 13th century. In the 17th century, signet rings fell out of favor in the upper levels of society, replaced by other means for mounting and carrying the signet. In the 18th century, though, signet rings again became popular, and by the 19th century, men of all classes wore them.
Since at least the 16th century there have also been pseudo-signet rings where the engraving is not reversed (mirror image), as it should be if the impression is to read correctly.
Rings have been used since antiquity as spy identification and in espionage. During World War II, US Air Force personnel would privately purchase signet rings with a hidden compartment that would hold small compass or hidden message. MI9 purchased a number of signet rings from Regent Street jewelers that were used to conceal compasses.
Modern tamper-proofing
In modern use, seals are used to tamper-proof equipment. For example, to prevent gas and electricity meters from being interfered with to show lower chargeable readings, they may be sealed with a lead or plastic seal with a government marking, typically fixed to a wire that passes through part of the meter housing. The meter cannot be opened without cutting the wire or damaging the seal.
Specially-made Tamper-evident technology, tamper-evident labels are available which are destroyed if the protected container or equipment is opened, functionally equivalent to a wax seal. They are used to protect things which must not be tampered with such as pharmaceuticals, equipment whose opening voids a manufacturer's warranty, etc.
