A seal is a device for making an impression in wax , 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).
65-500: A great seal is a seal used by a head of state, or someone authorised to do so on their behalf, to confirm formal documents, such as laws, treaties, appointments and letters of dispatch. It was and is used as a guarantee of the authenticity of the most important and solemn records and documents. In the Middle Ages , the great seal played a far greater political role and there was much real power associated with having control over
130-539: A minister of justice . Great seals of republics usually show the nation's coat of arms (e.g. the Great Seal of the United States ) or an allegorical image (e.g. France). For this reason, the design used usually remains unchanged. The seals themselves may, however, be replaced because of wear depending on how often the seal is used. In monarchies, by contrast, the great seal is often changed some time after
195-477: A daily basis. At least in Britain, each registered notary has an individual personal seal, registered with the authorities, which includes his or her name and a pictorial emblem, often an animal—the same combination found in many seals from ancient Greece. Seals are used primarily to authenticate documents, specifically those which carry some legal import. There are two main ways in which a seal may be attached to
260-477: A document. It may be applied directly to the face of the paper or parchment (an applied seal ); or it may hang loose from it (a pendent seal ). A pendent seal may be attached to cords or ribbons (sometimes in the owner's livery colors ), or to the two ends of a strip (or tag ) of parchment, threaded through holes or slots cut in the lower edge of the document: the document is often folded double at this point (a plica ) to provide extra strength. Alternatively,
325-736: A form of written identification since the Qin dynasty (221 BC–). The seals of the Han dynasty were impressed in a soft clay, but from the Tang dynasty a red ink made from cinnabar was normally used. Even in modern times, seals, often known as "chops" in local colloquial English, are still commonly used instead of handwritten signatures to authenticate official documents or financial transactions. Both individuals and organizations have official seals, and they often have multiple seals in different sizes and styles for different situations. East Asian seals usually bear
390-407: 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 and subsequent election of a new Pope. Signet rings are also used as
455-483: 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 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
520-419: A lever-press or a screw press . 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
585-414: A manufacturer's warranty, etc. The expression "seal of approval" refers to a formal approval, regardless whether it involves a seal or other external marking, by an authoritative person or institute. It is also part of the formal name of certain quality marks, such as: Sigillography Sigillography , also known by its Greek-derived name, sphragistics , is the scholarly discipline that studies
650-629: A means of cancelling them. When King James II of England was dethroned in the Glorious Revolution of 1688/9, he is supposed to have thrown the Great Seal of the Realm into the River Thames before his flight to France in order to ensure that the machinery of government would cease to function. It is unclear how much truth there is to this story, but certainly the seal was recovered: James's successors, William III and Mary used
715-691: A name written in Aramaic (Yitsḥaq bar Ḥanina) engraved in reverse so as to read correctly in the impression. From the beginning of the 3rd millennium BC until the Middle Ages, seals of various kinds were in production in the Aegean islands and mainland Greece. In the Early Minoan age these were formed of soft stone and ivory and show particular characteristic forms. By the Middle Minoan age

The Late Bronze Age is the time par excellence of the lens-shaped seal and the seal ring, which continued into the Archaic , Classical and Hellenistic periods, in the form of pictorial engraved gems . These were a major luxury art form and became keenly collected, with King Mithridates VI of Pontus
845-478: A seal. The practice spread, and it seems to be taken for granted by King Clovis I at the very beginning of the Merovingian dynasty . Later ecclesiastical synods require that letters under the bishop 's seal should be given to priests when for some reason they lawfully quit their own proper diocese. Such a ruling was enacted at Chalon-sur-Saône in 813. Pope Nicholas I in the same century complained that
910-461: 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
975-431: A souvenir or membership attribute, e.g., class rings (which typically bear the coat of arms or crest of the school). One may also have their initials engraved as a sign of their personal stature. Traditionally, signet rings were worn either on the little or the ring finger of the least dominant hand, with the most common usage being on the little. The less noble classes began wearing and using signet rings as early as
1040-620: A variety of hard materials, including wood, soapstone, sea glass and jade. East Asian seals are traditionally used with a red oil-based paste consisting of finely ground cinnabar, which contrasts with the black ink traditionally used for the ink brush . Red chemical inks are more commonly used in modern times for sealing documents. Seal engraving is considered a form of calligraphy 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
1105-481: A way that the item could not be opened without the seal being broken. Applied seals were used on letters close (letters intended only for the recipient) and parcels to indicate whether or not the item had been opened or tampered with since it had left the sender, as well as providing evidence that the item was actually from the sender and not a forgery. In the post-medieval period, seals came to be commonly used in this way for private letters . A letter writer would fold
1170-509: 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 instruments and to letters patent (i.e. open letters) conferring rights or privileges, which were intended to be available for all to view. In
1235-443: 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 parchment , running through them. These "pendent" seal impressions dangled below
1300-555: Is now unusual in most countries in the west for private citizens to use seals. 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. Notaries also still use seals on
1365-566: 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 's hand; he arrayed him in garments of fine linen, and put

From ancient Egypt seals in the form of signet rings , including some with the names of kings, have been found; these tend to show only names in hieroglyphics . Recently, seals datable to the Himyarite age have come to light in South Arabia . One example shows
1495-399: 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
1560-593: The Oxford English Dictionary date from 1879 ( sigillography ) and 1882 ( sigillographer ). The alternative term, sphragistics , is derived from the Greek word σϕρᾱγίς , meaning 'seal': this word is first recorded in English in 1836. Antiquaries such as Thomas Elmham and John Rous began to record and to discuss the historic use of seals in the 15th century. In the 16th and 17th centuries
1625-603: The Papal Chancery these leaden authentications fell out of favour in western Christendom. Byzantine Emperors sometimes issued documents with gold seals, known as Golden Bulls . 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:
1690-508: The Ring of the Fisherman , the papal signet, and to see that it is broken up. A similar practice prevailed in the Middle Ages and it is often alluded to by historians, as it seems to have been a matter of some ceremony. For example, on the death of Robert of Holy Island , Bishop of Durham, in 1283, the chronicler Robert Greystones reports: "After his burial, his seal was publicly broken up in
1755-510: The auxiliary sciences of history . A student of seals is known as a sigillographer . The word sigillography derives from the Latin word sigillum , meaning 'seal', and the Greek suffix γραφή , meaning 'description'. It was effectively coined in Italian (as sigillografia ) by Anton Stefano Cartari in 1682. It entered English at a much later date: the earliest instances recorded by

It investigates not only aspects of the artistic design and production of seals (both matrices and impressions), but also considers the legal, administrative and social contexts in which they were used. It has links to diplomatics , heraldry , social history , and the history of art , and is regarded as one of
1885-429: 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
1950-506: The Middle Ages, this generally comprised a compound of about two-thirds beeswax to one-third of some kind of resin , but in the post-medieval period the resin (and other ingredients) came to dominate. During the early Middle Ages seals of lead, or more properly " bullae " (from the Latin), were in common use both in East and West, but with the notable exception of documents (" bulls ") issued by
2015-563: The United States, the word "seal" is sometimes assigned to a facsimile of the seal design (in monochrome or color), which may be used in a variety of contexts including architectural settings, on flags , or on official letterheads . Thus, for example, the Great Seal of the United States , among other uses, appears on the reverse of the one-dollar bill ; and several of the seals of the U.S. states appear on their respective state flags . In Europe, although coats of arms and heraldic badges may well feature in such contexts as well as on seals,

Seal (emblem) 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,

There is a direct line of descent from the seals used in the ancient world, to those used in medieval and post-medieval Europe, and so to those used in legal contexts in the western world to the present day. Seals were historically most often impressed in sealing wax (often simply described as "wax"): in
2210-596: The bishops of Dôle and Reims had, " contra morem " (contrary to custom), sent their letters to him unsealed. The custom of bishops possessing seals may from this date be assumed to have been pretty general. In the British Museum collection the earliest bishop's seals preserved are those of William de St-Calais , Bishop of Durham (1081–96) and of St. Anselm, Archbishop of Canterbury (1093–1109). Seals are also affixed on architectural or engineering construction documents, or land survey drawings, to certify

Most governments still attach pendent seals to letters patent . Applied seals, by contrast, were originally used to seal a document closed: that is to say, the document would be folded and the seal applied in such
2340-426: 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
2405-542: The completed letter, pour wax over the joint formed by the top of the page, and then impress a ring or other seal matrix. Governments sometimes sent letters to citizens under the governmental seal for their eyes only, known as letters secret. Wax seals might also be used with letterlocking techniques to ensure that only the intended recipient would read the message. In general, seals are no longer used in these ways except for ceremonial purposes. However, applied seals also came to be used on legal instruments applied directly to
2470-531: The consideration of seals became a fairly widespread antiquarian activity. Notable early students and collectors included Robert Glover , John Dee , Sir Robert Cotton and Nicolas-Claude de Peiresc . The first published treatises dedicated to seals included Giorgio Longo's De anulis signatoriis antiquorum (Milan, 1615); Olivier de Wree 's Sigilla comitum Flandriae (Bruges, 1639); and Theodorus Hoepingk's De sigillorum prisco et novo jure tractatus (Nuremberg, 1642).

2730-403: The earliest civilizations and are of considerable importance in archaeology and art history . In ancient Mesopotamia carved or engraved cylinder seals in stone or other materials were used. These could be rolled along to create an impression on clay (which could be repeated indefinitely), and used as labels on consignments of trade goods, or for other purposes. They are normally hollow and it

Historically, the majority of seals were circular in design, although ovals, triangles, shield-shapes and other patterns are also known. The design generally comprised a graphic emblem (sometimes, but not always, incorporating heraldic devices ), surrounded by a text (the legend ) running around the perimeter. The legend most often consisted merely of

Engraved gems continued to be produced and collected until the 19th century. Pliny also explained the significance of the signet ring, and how over time this ring was worn on the little finger. Known as yinzhang ( Chinese : 印章 ) in Greater China , injang in Korea , inshō in Japan , ấn triện (or ấn chương ) in Vietnam , seals have been used in East Asia as

Depending on the authority having jurisdiction for the project, these seals may be embossed and signed, stamped and signed, or in certain situations a computer generated facsimile of the original seal validated by a digital certificate owned by the professional may be attached to a security protected computer file. The identities on
3055-580: 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 a small compass or hidden message. MI9 purchased a number of signet rings from Regent Street jewelers that were used to conceal compasses. 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

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 engraved gems were often carved in relief, called cameo in this context, giving a "counter-relief" or intaglio impression when used as seals. The process

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,
3250-527: The middle of the 13th century. They also came to be used by a variety of corporate bodies, including cathedral chapters , municipalities, monasteries etc., to validate the acts executed in their name. Traditional wax seals continue to be used on certain high-status and ceremonial documents, but in the 20th century they were gradually superseded in many other contexts by inked or dry embossed seals and by rubber stamps . While many instruments formerly required seals for validity (e.g. deeds or covenants ) it
3315-402: The names of the people or organizations represented, but they can also bear poems or personal mottoes. Sometimes both types of seals, or large seals that bear both names and mottoes, are used to authenticate official documents. Seals are so important in East Asia that foreigners who frequently conduct business there also commission the engraving of personal seals. East Asian seals are carved from

#17327585447983380-630: The owner, or (in the case of ecclesiastical seals) of a saint. Medieval townspeople used a wide variety of different emblems but some had seals that included an image relating to their work. Sealing wax 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
3445-474: The presence of all by Master Robert Avenel." Matthew Paris gives a similar description of the breaking of the seal of William of Trumpington, Abbot of St Albans , in 1235. 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
3510-679: The professional seals determine legal responsibility for any errors or omissions, and in some cases financial responsibility for their correction as well as the territory of their responsibility, e.g.: "State of Minnesota". 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

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 , created in intaglio so that it will leave a raised ( relief ) impression of the design when the ring is pressed onto liquid sealing wax . The design

One of the largest compendiums of Byzantine seals can be found in the large volume by Gustave Schlumberger , Sigillographie de l'empire Byzantin , published in 1904. The first international colloquium on Byzantine sigillography was held at Dumbarton Oaks in August 1986. Sigillography features in
3705-490: The seal design in its entirety rarely appears as a graphical emblem and is used mainly as originally intended: as an impression on documents. The study of seals is known as sigillography or sphragistics. The stamp seal was a common seal die, frequently carved from stone, known at least since the 6th millennium BC ( Halaf culture ) and probably earlier. The oldest stamp seals were button-shaped objects with primitive ornamental forms chiseled onto them. Seals were used in
3770-414: 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 (raised above the surface). The design on the impression will reverse (be a mirror-image of) that of
3835-457: 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

The seal is usually formally entrusted upon an office-holder to act as keeper of the seal . This keeper may be a separate office but was also usually combined with that of the chancellor . Nowadays, the great seal is usually entrusted upon a minister, particularly
3965-458: The second half of the 19th century sigillography was further developed by German scholars including Hermann Grotefend and Otto Posse , and French scholars including Louis Douët d'Arcq and Germain Demay .

Although it is a utilitarian instrument of daily business in East Asia, westerners and other non-Asians seldom see Asian seals except on Asian paintings and calligraphic art. All traditional paintings in China , Japan , Korea , and the rest of East Asia are watercolor paintings on silk, paper, or some other surface to which the red ink from seals can adhere. East Asian paintings often bear multiple seals, including one or two seals from
