Mainz in the context of "Carl Zeiss AG"

The Main (German pronunciation: [ˈmaɪn] ) is the longest tributary of the Rhine, one of the major European rivers. It rises as the White Main in the Fichtel Mountains of northeastern Bavaria and flows west through central Germany for 525 kilometres (326 mi) to meet the Rhine below Rüsselsheim, Hesse. The cities of Mainz and Wiesbaden are close to the confluence.

The largest cities on the Main are Frankfurt am Main, Offenbach am Main and Würzburg. It is the longest river lying entirely in Germany (if the Weser-Werra are considered separate).

Rhineland-Palatinate (/ˌraɪnlænd pəˈlætɪnɪt, -lənd-/ RYNE-land pə-LAT-in-it, -⁠lənd-, US also /-ɪneɪt/ -⁠in-ayt; German: Rheinland-Pfalz [ˌʁaɪnlant ˈpfalts] ; Luxembourgish: Rheinland-Pfalz [ˌʀɑɪ̯nlɑm ˈpfɑlts]; Palatine German: Rhoilond-Palz) is a western state of Germany. It covers 19,846 km (7,663 sq mi) and has about 4.05 million residents. It is the ninth largest and sixth most populous of the sixteen states. Mainz is the capital and largest city. Other cities are Ludwigshafen am Rhein, Koblenz, Trier, Kaiserslautern, Worms, and Neuwied. It is bordered by North Rhine-Westphalia, Saarland, Baden-Württemberg and Hesse and by France, Luxembourg and Belgium.

Rhineland-Palatinate was established in 1946 after World War II, from parts of the former states of Prussia (part of its Rhineland and Nassau provinces), Hesse (Rhenish Hesse) and Bavaria (its former outlying Palatinate kreis or district), by the French military administration in Allied-occupied Germany. Rhineland-Palatinate became part of the Federal Republic of Germany in 1949 and shared the country's only border with the Saar Protectorate until the latter was returned to German control in 1957. Rhineland-Palatinate's natural and cultural heritage includes the extensive Palatinate winegrowing region, picturesque landscapes, and many castles and palaces.

The Rhine-Main Metropolitan Region, often simply referred to as Frankfurt Rhine-Main, Frankfurt Rhine-Main area or Rhine-Main area (German: Rhein-Main-Gebiet, Frankfurt/Rhein-Main or FrankfurtRheinMain, abbreviated FRM), is the third-largest metropolitan region in Germany after Rhine-Ruhr and Berlin-Brandenburg, with a total population exceeding 5.9 million. The metropolitan region is located in the central-western part of Germany, and stretches over parts of three German states: Hesse, Rhineland-Palatinate, and Bavaria. The largest cities in the region are Frankfurt am Main, Wiesbaden, Mainz, Darmstadt, Offenbach, Worms, Hanau, and Aschaffenburg.

The polycentric region is named after its core city, Frankfurt, and the two rivers Rhine and Main. The Frankfurt Rhine-Main area is officially designated as a European Metropolitan region by the German Federal Ministry of Transport, Building and Urban Affairs and covers an area of roughly 13,000 square kilometers (5,000 sq mi).

Following the invention of the printing press in the German city of Mainz by Johannes Gutenberg c. 1439, Western printing technology spread across the world, and was adopted worldwide by the end of the 19th century. The technology, which mechanized the process of printing with moveable type, displaced the manuscript and block printing.

In the Western world, the operation of a press became synonymous with the enterprise of publishing and lent its name to a new branch of media, the "press" (see List of the oldest newspapers).

Lucius Antonius Saturninus was a Roman senator and general during the reign of Vespasian and his sons. While governor of the province called Germania Superior, motivated by a personal grudge against Emperor Domitian, he led a rebellion known as the Revolt of Saturninus, involving the legions Legio XIV Gemina and Legio XXI Rapax, camped in Moguntiacum (Mainz).

The Limes Germanicus (Latin for Germanic frontier), or 'Germanic Limes', is the name given in modern times to a line of frontier (limes) fortifications that bounded the ancient Roman provinces of Germania Inferior, Germania Superior and Raetia, dividing the Roman Empire and the unsubdued Germanic tribes from the years 83 to about 260 AD. The frontier used either a natural boundary such as a river or typically an earth bank and ditch with a wooden palisade and watchtowers at intervals, and a system of linked forts was built behind them.

The path of the limes changed over time following advances and retreats due to pressure from external threats. At its height, the Limes Germanicus stretched from the North Sea outlet of the Rhine to near Regensburg (Castra Regina) on the Danube. These two major rivers afforded natural protection from mass incursions into imperial territory, with the exception of a gap stretching roughly from Mogontiacum (now Mainz) on the Rhine to Castra Regina.

The Gutenberg Bible, also known as the 42-line Bible, the Mazarin Bible or the B42, was the earliest major book printed in Europe using mass-produced metal movable type. It marked the start of the "Gutenberg Revolution" and the age of printed books in the West. The book is valued and revered for its high aesthetic and artistic qualities and its historical significance.

The Gutenberg Bible is an edition of the Latin Vulgate printed in the 1450s by Johannes Gutenberg in Mainz (Holy Roman Empire), in present-day Germany. Out of either 158 or 180 copies that were originally printed, 49 survive in at least substantial portion, 21 of them in entirety; of these, the copy with the earliest visible print date is marked as 15 August 1456. They are thought to be among the world's most valuable books, although no complete copy has been sold since 1978. In March 1455, the future Pope Pius II wrote that he had seen pages from the Gutenberg Bible, displayed in Frankfurt to promote the edition.

Erhard Reuwich (Dutch: Reeuwijk) was a Dutch artist, as a designer of woodcuts, and a printer, who came from Utrecht but then worked in Mainz. His dates and places of birth and death are unknown, but he was active in the 1480s.

He came from a family of painters in Utrecht, and his father may have been Hildebrand Reuwich, who was Dean of the painters' guild there in 1470. He traveled on a pilgrimage to Jerusalem, which gave rise to his most famous work. It has been suggested that he was the Master of the Housebook, but this has not been generally accepted. Perhaps more likely is his identification as an engraver known as the Master of the Book of Reason.
