Ancient Near Eastern seals and sealing practicesW
Ancient Near Eastern seals and sealing practices

Two main types of seals were used in the Ancient Near East, the stamp seal and the cylinder seal. Stamp seals first appeared in ‘administrative’ contexts in central and northern Mesopotamia in the seventh millennium and were used exclusively until the fifth millennium. Cylinder seals appeared first around 3600 bc in southern Mesopotamia and south-western Iran. They gradually replaced stamp seals, becoming the tool of a rising class of bureaucrats in the early stages of state formation. Even though stamp seals were still produced in the third and second millennia, cylinder seals predominated. In the first millennium, stamp seals made a strong comeback and eventually replaced cylinder seals entirely.

Crusader statesW
Crusader states

The Crusader States, also known as Outremer, were four Roman Catholic realms in the Middle East that lasted from 1098 to 1291. These feudal polities were created by the Latin Catholic leaders of the First Crusade through conquest and political intrigue. The four states were the County of Edessa (1098–1150), the Principality of Antioch (1098–1287), the County of Tripoli (1102–1289), and the Kingdom of Jerusalem (1099–1291). The kingdom of Jerusalem covered what is now Israel and Palestine, the West Bank, the Gaza Strip, and adjacent areas. The other northern states covered what are now Syria, south-eastern Turkey, and Lebanon. The description "Crusader states" can be misleading, as from 1130 very few of the Frankish population were crusaders. The term Outremer, used by medieval and modern writers as a synonym, is derived from the French for overseas.

Cylinder sealW
Cylinder seal

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 iron, silver, beads, and gemstones often included one or two cylinder seals, as honorific grave goods.

Engraved gemW

A golden bull or chrysobull was a decree issued by Byzantine Emperors and later by monarchs in Europe during the Middle Ages and Renaissance, most notably by the Holy Roman Emperors. The term was originally coined for the golden seal, attached to the decree, but came to be applied to the entire decree. Such decrees were known as golden bulls in western Europe and chrysobullos logos, or chrysobulls, in the Byzantine Empire.

LMLK seals are ancient Hebrew seals stamped on the handles of large storage jars first issued in the reign of King Hezekiah and discovered mostly in and around Jerusalem. Several complete jars were found in situ buried under a destruction layer caused by Sennacherib at Lachish. While none of the original seals have been found, some 2,000 impressions made by at least 21 seal types have been published. The iconography of the two and four winged symbols are representative of royal symbols whose meaning "was tailored in each kingdom to the local religion and ideology".

The Luther seal or Luther rose is a widely recognized symbol for Lutheranism. It was the seal that was designed for Martin Luther at the behest of John Frederick of Saxony in 1530, while Luther was staying at the Coburg Fortress during the Diet of Augsburg. Lazarus Spengler, to whom Luther wrote his interpretation below, sent Luther a drawing of this seal. Luther saw it as a compendium or expression of his theology and faith, which he used to authorize his correspondence. Luther informed Philipp Melanchthon on September 15, 1530, that the Prince had personally visited him in the Coburg fortress and presented him with a signet ring, presumably displaying the seal.

Seal (contract law)W
Seal (contract law)

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.

Seal of Charlotte, North CarolinaW
Seal of Charlotte, North Carolina

The Seal of Charlotte was first established during the tenure of mayor Charles A. Bland, and was designed over a period stretching from 1911 to 1915. It was adopted on the city's first flag in 1929, which still remains in use today. This seal itself was rescinded at an unknown date and replaced with the present one. In its current form, it is the city's logo on a golden seal, and it is used to authorize executive documents from the city, including, but not limited to, mayoral proclamations and resolutions from the city council. Based on the adoption of the crown logo in 1985 with the current flags, it is possible the current seal could have been adopted at that time as well, however, this is unknown, and city archives from the era do not depict any seal.

Seal of MindaugasW

Seal script

Seal script is an ancient style of writing Chinese characters that was common throughout the latter half of the 1st millennium BC. It evolved organically out of the Zhou dynasty bronze script. The Qin variant of seal script eventually became the standard, and was adopted as the formal script for all of China during the Qin dynasty. It was still widely used for decorative engraving and seals in the Han dynasty. The literal translation of the Chinese name for seal script, 篆書, is decorative engraving script, a name coined during the Han dynasty, which reflects the then-reduced role of the script for the writing of ceremonial inscriptions.

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.
