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, a wrapper for one such as a modern envelope, or the cover of a container or package holding valuables or other objects.
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 (raised above the surface). 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 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 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 the documents they authenticated, to which the attachment tag was sewn or otherwise attached (single-sided seals were treated in the same way).
Some jurisdictions consider rubber stampsor specified signature-accompanying words such as "seal" or "L.S." (abbreviation of locus sigilli, "place of the seal") to be the legal equivalent of, i.e., an equally effective substitute for, a seal.
In 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, 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.
Seals were used in 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 is presumed that they were worn on a string or chain round the neck. Many have only images, often very finely carved, with no writing, while others have both. 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[ citation needed ], seals have come to light in South Arabia datable to the Himyarite age. One example shows 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 a new set for seal forms, motifs and materials appear. Hard stone requires new rotary carving techniques. 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 the first major collector according to Pliny the Elder. His collection fell as booty to Pompey the Great, who deposited it in a temple in Rome. 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 giám (or ấn chương) in Vietnam, seals have been used in East Asia as 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 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 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 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.
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 Taiwan, 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 the artist, and the seals from the owners of the paintings.
East Asian seals are the predecessors to block printing.
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 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 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: 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 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 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[ citation needed ], 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 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 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, 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 instruments and to letters patent (i.e. open letters) conferring rights or privileges, which were intended to be available for all to view. In the case of important transactions or agreements, the seals of all parties to the arrangement as well as of witnesses might be attached to the document, and so once executed it would carry several seals. 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 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 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 the face of the document, so that there was no need to break them, and this use continues.
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 the words "The seal of [the name of the owner]", either in Latin or in the local vernacular language: the Latin word Sigillum was frequently abbreviated to a simple S:. Occasionally, the legend took the form of a motto.
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. 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 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. 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 western Europe in the 12th century.
Ecclesiastical seals are frequently mandorla-shaped, as in the shape of an almond, also known as vesica-shaped. The use of a seal by men of wealth and position was common before the Christian era, but high functionaries of the Church adopted the habit. An incidental allusion in one of St. Augustine's letters (217 to Victorinus) indicates that he used 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 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 the identity of the licensed professional who supervised the development.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 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 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 importance of the seal as a means of authentication necessitated that when authority passed into new hands the old seal should be destroyed and a new one made. When the pope dies it is the first duty of the Cardinal Camerlengo to obtain possession of 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 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 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 the same Great Seal matrix, fairly crudely adapted – possibly quite deliberately, in order to demonstrate the continuity of government.
A related practice of destruction is found among blacksmiths: their touchmark (a stamp used on the hot metal to show who made it) is destroyed upon their death.

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 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 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 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.[ citation needed ]
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.
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:

Printmaking is the process of creating artworks by printing, normally on paper. Printmaking normally covers only the process of creating prints that have an element of originality, rather than just being a photographic reproduction of a painting. Except in the case of monotyping, the process is capable of producing multiples of the same piece, which is called a print. Each print produced is considered an "original" work of art, and is correctly referred to as an "impression", not a "copy". Often impressions vary considerably, whether intentionally or not. The images on most prints are created for that purpose, perhaps with a preparatory study such as a drawing. A print that copies another work of art, especially a painting, is known as a "reproductive print".
Engraving is the practice of incising a design onto a hard, usually flat surface by cutting grooves into it with a burin. The result may be a decorated object in itself, as when silver, gold, steel, or glass are engraved, or may provide an intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking. Wood engraving is a form of relief printing and is not covered in this article.
A papal bull is a type of public decree, letters patent, or charter issued by a pope of the Catholic Church. It is named after the leaden seal (bulla) that was traditionally appended to the end in order to authenticate it.
Rubber stamping, also called stamping, is a craft in which some type of ink made of dye or pigment is applied to an image or pattern that has been carved, molded, laser engraved or vulcanized, onto a sheet of rubber. The rubber is often mounted onto a more stable object such as a wood, brick or an acrylic block. Increasingly the vulcanized rubber image with an adhesive foam backing is attached to a cling vinyl sheet which allows it to be used with an acrylic handle for support. These cling rubber stamps can be stored in a smaller amount of space and typically cost less than the wood mounted versions. They can also be positioned with a greater amount of accuracy due to the stamper's ability to see through the handle being used. Temporary stamps with simple designs can be carved from a potato. The ink-coated rubber stamp is pressed onto any type of medium such that the colored image is transferred to the medium. The medium is generally some type of fabric or paper. Other media used are wood, metal, glass, plastic, and rock. High-volume batik uses liquid wax instead of ink on a metal stamp.
Sealing wax is a wax material of a seal which, after melting, hardens quickly forming a bond that is difficult to separate without noticeable tampering. Wax is used to verify something such as a document is unopened, to verify the sender's identity, for example with a signet ring, and as decoration. Sealing wax can be used to take impressions of other seals. Wax was used to seal letters close and later, from about the 16th century, envelopes. Before sealing wax, the Romans used bitumen for this purpose.
The Seal of Solomon is the signet ring attributed to King Solomon in medieval Arabic tradition, from which it developed in Islamic and Jewish mysticism and in Western occultism. It is the predecessor of the Star of David, which became the symbol of the Jewish people in modern times.
A seal, in an East and Southeast Asian context, is a general name for printing stamps and impressions thereof which are used in lieu of signatures in personal documents, office paperwork, contracts, art, or any item requiring acknowledgement or authorship. In the western world they were traditionally known by traders as chop marks or simply chops. The process started in China and soon spread across East Asia. China, Japan and Korea currently use a mixture of seals and hand signatures, and, increasingly, electronic signatures.
Tamper-evident describes a device or process that makes unauthorized access to the protected object easily detected. Seals, markings, or other techniques may be tamper indicating.
The Ring of the Fisherman, also known as the Piscatory Ring, is an official part of the regalia worn by the Pope, who is head of the Catholic Church and successor of Saint Peter, who was a fisherman by trade. It used to feature a bas-relief of Peter fishing from a boat, a symbolism derived from the tradition that the apostles were "fishers of men". The Fisherman's Ring is a signet used until 1842 to seal official documents signed by the Pope. Since at least the Middle Ages it has been a tradition for Catholics meeting the Pope to show their devotion by kissing the ring.
A cylinder seal is a small round cylinder, typically about one inch in length, engraved with written characters or figurative scenes or both, used in ancient times to roll an impression onto a two-dimensional surface, generally wet clay. According to some sources, cylinder seals were invented around 3500 BC in the Near East, at the contemporary sites of Uruk in southern Mesopotamia and slightly later at Susa in south-western Iran during the Proto-Elamite period, and they follow the development of stamp seals in the Halaf culture or slightly earlier. They are linked to the invention of the latter's cuneiform writing on clay tablets. Other sources, however, date the earliest cylinder seals to a much earlier time, to the Late Neolithic period, hundreds of years before the invention of writing. They were used as an administrative tool, a form of signature, as well as jewelry and as magical amulets; later versions would employ notations with Mesopotamian cuneiform. In later periods, they were used to notarize or attest to multiple impressions of clay documents. Graves and other sites housing precious items such as gold, silver, beads, and gemstones often included one or two cylinder seals, as honorific grave goods.
The impression seal is a common seal that leaves an impression, typically in clay and less often in sealing wax. In antiquity they were common, largely because they served to authenticate legal documents, such as tax receipts, contracts, wills and decrees. They are favorite topics of study because they were usually carved with important "themes" of the society that produced them, rather than with an ordinary signature.
Sigillography, also known by its Greek-derived name, sphragistics, is the scholarly discipline that studies the wax, lead, clay, and other seals used to authenticate archival documents. It investigates not only aspects of the artistic design and production of seals, 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 the auxiliary sciences of history. A student of seals is known as a sigillographer.
The Great Seal of France is the official seal of the French Republic. After the 1792 revolution established the First French Republic, the insignia of the monarchy was removed from the seal. Over time, the new seal changed. At first, it featured Marianne, symbol of the revolution. It evolved to show that the people developed their culture and politics. In modern times, it depicts liberty, along with aspects of culture such as art, education, and agriculture.
A bulla is an inscribed clay or soft metal or bitumen or wax token used in commercial and legal documentation as a form of authentication and for tamper-proofing whatever is attached to it.
A papal brief or breve is a formal document emanating from the Pope, in a somewhat simpler and more modern form than a papal bull.
A merchant's mark is an emblem or device adopted by a merchant, and placed on goods or products sold by him in order to keep track of them, or as a sign of authentication. It may also be used as a mark of identity in other contexts.
In the law, a seal affixed to a contract or other legal instrument has had special legal significance at various times in the jurisdictions that recognise it. In the courts of common law jurisdictions, a contract which was sealed was treated differently from other written contracts, although this practice gradually fell out of favour in most of these jurisdictions in the 19th and early 20th century. The legal term seal arises from the wax seal used throughout history for authentication.
An engraved gem, frequently referred to as an intaglio, is a small and usually semi-precious gemstone that has been carved, in the Western tradition normally with images or inscriptions only on one face. The engraving of gemstones was a major luxury art form in the Ancient world, and an important one in some later periods.
Minoan seals are impression seals in the form of carved gemstones and similar pieces in metal, ivory and other materials produced in the Minoan civilization. They are an important part of Minoan art, and have been found in quantity at specific sites, for example in Knossos, Mallia and Phaistos. They were evidently used as a means of identifying documents and objects.
Seal of Muhammad is one of the relics of Muhammad kept in the Topkapı Palace by the Ottoman Sultans as part of the Sacred Relics collection. It is allegedly the replica of a seal used by Muhammad on several letters sent to foreign dignitaries.
