Water pipe with Latin inscription from the reign of Vespasian. The text is unusual for being sunk into the surface and its sizable length of 1 m.[1]

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]

Manufacture of pipes

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]

Creation of inscriptions

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:

    On balance, material evidence, practical and economical considerations, as well as the available data, clearly support the notion that text stamps were employed.
