A mark is a written or imprinted symbol used to indicate some trait of an item, for example, its ownership or maker.[1][2] Mark usually consists of letters, numbers, words, and drawings.[3] Inscribing marks on the manufactured items was likely a precursor of communicative writing.[4]
Historically, the marks were used for few purposes:[5]
In the 17th century in the English cloth trade a new class of marks was created, now called trademarks: the cloth was required to contain both the maker's mark (initials of the maker) and the mark of the clothier, indicating the capitalist who furnished the capital for the production.[8]
The ownership marks (at the time simultaneously the maker's) are the oldest ones (per Rabelais, "the sense of ownership of his works is as natural to man as laughing"[3]). Some researchers claim that the decorations found on the shells of ostrich eggs in South Africa and dating back 60,000 years are marks of the owner.[10]
The manufacturer's marks are quite old: the ones found on Korakou culturepottery are four thousand years old, and the ones on ancient Greek and Roman vases date back to 5th-4th centuries BC.[13] While the production marks are technically distinct from the ownership marks, in the ancient times, when a craftsman typically was the same person as the merchant, and many people were illiterate, a single mark frequently served both purposes.[14] The rise of factory marks (at the expense of the marks of actual makers) was occurring in many industries since the 17th century, De Munck links this to changes in the labor relations and methods of production (molds for earthenware, for example, reduced potters to low-skilled laborers).[15]

The distinction between the factory marks and trademarks in England became clear by the 17th century in the cloth trade: the manufacturer marks (initials of the maker weaved into the cloth) were required from the producers by regulations and represented a liability, while the trademark (mark of the clothier) represented the goodwill, an asset, not of the actual craftsman, but of the capitalist who furnished the capital for the production.[8]
Medieval guilds set up the system of compulsory ("regulatory") marks for the craftsmen, intended to trace the defective items and punish the offenders,[16] with most typical examples provided by the bakery trade.[17] In English weapons manufacturing (including cutlery) the regulations concerning the manufacturer marks were firmly established in the 14th century: no weapon shall be sold without a personal mark of the craftsman, misuse of the mark was subject to court actions.[18]
Marks on ceramics
Signaculum PRIMIT ("first")
While occasionally the marks were directly etched onto ceramic objects, the nature of the manufacturing process was amenable to the use of seals. The oldest stamp seals were button-shaped objects with primitive ornamental forms chiseled onto them.[19] In the fourth millennium BC, Sumerians introduced cylinder seals that had to be rolled over the soft clay to leave an imprint.[20] From the 12th century BC the previous designs were largely abandoned in favor of amphora stamps.[6]Romans introduced their signacula, true manufacturer's marks, around the first century BC;[6]Byzantine maintained the tradition in their commercial stamps.[21]
