A Roman lead pipe inscription is a Latin inscription on a Roman water pipe made of lead which provides brief information on its manufacturer and owner, often the reigning emperor himself as the supreme authority. The identification marks were created by full text stamps. [2]
Lead, a by-product of the ancient silver smelting process, was produced in the Roman Empire with an estimated peak production of 80,000 metric tons per year –a truly industrial scale. [3] The metal was used along with other materials in the vast water supply network of the Romans for the manufacture of water pipes, particularly for urban plumbing. [4]
The method of manufacturing the lead pipes is recorded by Vitruvius and Frontinus. [5] The lead was poured into sheets of a uniform 3 m (10 ft) length, which were bent to form a cylinder and soldered at the seam. [6] The lead pipes could range in size from approximately 1.3 to 57 cm (0.5 to 22.4 in) in diameter, depending on the required rate of flow. [7]
Since the 19th century, the hypothesis has occasionally been put forward that the Roman inscriptions were created by movable type printing. [8] A recent investigation by the typesetter and linguist Herbert Brekle, however, concludes that all material evidence points to the use of common text stamps. [9] Brekle describes the manufacturing method as follows:
A stamp (punch) which has the text carved in high-relief and in right reading is pressed into the slightly moist sand or clay of the mould, thus producing a reverse image of the text (matrix) in bas-relief. After the molten lead is poured out in the mould, the inscription appears raised in high-relief on the surface of the lead pipe. This is today considered the most plausible hypothesis for the creation of such inscriptions (full text stamp). [10]
Brekle lists the following reasons for the employment of stamps and against that of movable type: for printing on lead sheets the way the Romans created them, it would be much more practical to use single stamp blocks than sets of individual letters, since the latter would be unstable and would have required a clamp or some similar mechanism to maintain the necessary cohesion. [11] Neither impressions of such clamps nor of the fine lines between the individual letters typical for the use of movable type are discernible in the inscriptions. [12] By contrast, the outer rim of one examined stamp block left a raised rectangular edge running around the inscription text, thus providing positive evidence for the use of such a printing device. [13]
In addition, evidence of the poor positioning of movable type, such as individual letters tilting to the right or left or deviating from the baseline – something which could have been expected to occur at least in a few extant specimens – is notably absent. [12] In those inscriptions where the letters are not properly aligned, the entire text is blurred, which clearly points to the use of full text stamps. [14] Finally, it needs to be considered that archaeological excavations have never unearthed ancient sets of movable type, whereas moulds with reversed inscription texts for stamp printing have indeed been recovered. [15]
Johannes Gensfleisch zur Laden zum Gutenberg was a German inventor, printer, publisher, and goldsmith who introduced printing to Europe with his mechanical movable-type printing press. His work started the Printing Revolution in Europe and is regarded as a milestone of the second millennium, ushering in the modern period of human history. It played a key role in the development of the Renaissance, Reformation, Age of Enlightenment, and Scientific Revolution, as well as laying the material basis for the modern knowledge-based economy and the spread of learning to the masses.
A printing press is a mechanical device for applying pressure to an inked surface resting upon a print medium, thereby transferring the ink. It marked a dramatic improvement on earlier printing methods in which the cloth, paper or other medium was brushed or rubbed repeatedly to achieve the transfer of ink, and accelerated the process. Typically used for texts, the invention and global spread of the printing press was one of the most influential events in the second millennium.
Typography is the art and technique of arranging type to make written language legible, readable and appealing when displayed. The arrangement of type involves selecting typefaces, point sizes, line lengths, line-spacing (leading), and letter-spacing (tracking), as well as adjusting the space between pairs of letters (kerning). The term typography is also applied to the style, arrangement, and appearance of the letters, numbers, and symbols created by the process. Type design is a closely related craft, sometimes considered part of typography; most typographers do not design typefaces, and some type designers do not consider themselves typographers. Typography also may be used as an ornamental and decorative device, unrelated to the communication of information.
Plumbing is any system that conveys fluids for a wide range of applications. Plumbing uses pipes, valves, plumbing fixtures, tanks, and other apparatuses to convey fluids. Heating and cooling (HVAC), waste removal, and potable water delivery are among the most common uses for plumbing, but it is not limited to these applications. The word derives from the Latin for lead, plumbum, as the first effective pipes used in the Roman era were lead pipes.
Printing is a process for mass reproducing text and images using a master form or template. The earliest non-paper products involving printing include cylinder seals and objects such as the Cyrus Cylinder and the Cylinders of Nabonidus. The earliest known form of printing as applied to paper was woodblock printing, which appeared in China before 220 AD for cloth printing. However, it would not be applied to paper until the seventh century. Later developments in printing technology include the movable type invented by Bi Sheng around 1040 AD and the printing press invented by Johannes Gutenberg in the 15th century. The technology of printing played a key role in the development of the Renaissance and the Scientific Revolution and laid the material basis for the modern knowledge-based economy and the spread of learning to the masses.
Movable type is the system and technology of printing and typography that uses movable components to reproduce the elements of a document usually on the medium of paper.
In the manufacture of metal type used in letterpress printing, a matrix is the mould used to cast a letter, known as a sort. Matrices for printing types were made of copper.
The study of the Roman economy, which is, the economies of the ancient city-state of Rome and its empire during the Republican and Imperial periods remains highly speculative. There are no surviving records of business and government accounts, such as detailed reports of tax revenues, and few literary sources regarding economic activity. Instead, the study of this ancient economy is today mainly based on the surviving archeological and literary evidence that allow researchers to form conjectures based on comparisons with other more recent pre-industrial economies.
The Aqua Appia was the first Roman aqueduct, constructed in 312 BC by the co-censors Gaius Plautius Venox and Appius Claudius Caecus, the same Roman censor who also built the important Via Appia.
The Romans constructed aqueducts throughout their Republic and later Empire, to bring water from outside sources into cities and towns. Aqueduct water supplied public baths, latrines, fountains, and private households; it also supported mining operations, milling, farms, and gardens.
Modern typographers view typography as a craft with a very long history tracing its origins back to the first punches and dies used to make seals and coinage currency in ancient times. The basic elements of typography are at least as old as civilization and the earliest writing systems—a series of key developments that were eventually drawn together into one systematic craft. While woodblock printing and movable type had precedents in East Asia, typography in the Western world developed after the invention of the printing press by Johannes Gutenberg in the mid-15th century. The initial spread of printing throughout Germany and Italy led to the enduring legacy and continued use of blackletter, Roman and italic types.
The Horti Lamiani was a luxurious complex of an ancient Roman villa with large gardens and outdoor rooms located on the Esquiline Hill in Rome, in the area around the present Piazza Vittorio Emanuele. They were created by the consul Lucius Aelius Lamia, a friend of Emperor Tiberius, and they soon became imperial property. They are of exceptional historical-topographical importance. Along with other ancient Roman horti on the Quirinal, Viminal and Esquiline hills, they were discovered during the construction work for the expansion of Rome at the end of 1800s.
Renaissance technology was the set of European artifacts and inventions which spread through the Renaissance period, roughly the 14th century through the 16th century. The era is marked by profound technical advancements such as the printing press, linear perspective in drawing, patent law, double shell domes and bastion fortresses. Sketchbooks from artisans of the period give a deep insight into the mechanical technology then known and applied.
The history of printing starts as early as 3500 BCE, when the proto-Elamite and Sumerian civilizations used cylinder seals to certify documents written in clay. Other early forms include block seals, hammered coinage, pottery imprints, and cloth printing. Initially a method of printing patterns on cloth such as silk, woodblock printing for texts on paper originated in China by the 7th century during the Tang dynasty, leading to the spread of book production and woodblock printing in other parts of Asia such as Korea and Japan. The Chinese Buddhist Diamond Sutra, printed by woodblock on 11 May 868, is the earliest known printed book with a precise publishing date. Movable type was invented by Chinese artisan Bi Sheng in the 11th century during the Song dynasty, but it received limited use compared to woodblock printing. Nevertheless, the technology spread outside China, as the oldest printed book using metal movable type was the Jikji, printed in Korea in 1377 during the Goryeo era.
The Tomb of the Scipios, also called the hypogaeum Scipionum, was the common tomb of the patrician Scipio family during the Roman Republic for interments between the early 3rd century BC and the early 1st century AD. Then it was abandoned and within a few hundred years its location was lost.
Metals and metal working had been known to the people of modern Italy since the Bronze Age. By 53 BC, Rome had expanded to control an immense expanse of the Mediterranean. This included Italy and its islands, Spain, Macedonia, Africa, Asia Minor, Syria and Greece; by the end of the Emperor Trajan's reign, the Roman Empire had grown further to encompass parts of Britain, Egypt, all of modern Germany west of the Rhine, Dacia, Noricum, Judea, Armenia, Illyria, and Thrace. As the empire grew, so did its need for metals.
The Prüfening dedicatory inscription is a high medieval inscription impressed on clay which was created in 1119, over three hundred years before Johannes Gutenberg, by the typographic principle. The inscription plate belongs to the Prüfening Abbey, a former Benedictine monastery, in Regensburg, Germany.
Medieval letter tiles are one-letter ceramic tiles that were employed in monasteries and churches of the late Middle Ages for the creation of Christian inscriptions on floors and walls. They were created by pressing stamps bearing a reverse image into soft clay, which was then baked hard, and they were used to form words by assembling single-letter tiles in the desired order.
MS 5236 is an ancient Greek amulet of the 6th century BC, which is unique in two respects: it is the only known magic amulet of the time inscribed with a text that was stamped as opposed to incised, and it is the only extant specimen of ephesia grammata made of gold. The only partially comprehensible inscription is an invocation of the god Phoebus Apollo and may have been composed in central Greece or western Asia Minor. As such magical amulets are known to have been mass-produced, the existence of MS 5236 indicates that, despite the singularity of the foil, an inkless block printing process was practised in ancient Greece to a certain degree, for texts of some length, beyond the examples known from Roman lead pipe inscriptions and the many types of stamps used to mark bricks and pottery with the maker's name and other details.
The altarpiece of Pellegrino II is a medieval altarpiece in the cathedral of Cividale, Italy. The silver relief was endowed by Pellegrino II, the patriarch of Aquileia, around 1200 and adorns today the main altar of the church Santa Maria Assunta. It shows Mary and the Child Jesus surrounded by archangels and groups of saints. The piece is notable for its rich ornamentation and its early typographic inscription.
On balance, material evidence, practical and economical considerations, as well as the available data, clearly support the notion that text stamps were employed.
