Prüfening dedicatory inscription

The Prüfening dedicatory inscription (Prüfeninger Weiheinschrift) 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. The Latin inscription is still at its original location in Prüfening Abbey, attached to one of the main pillars of its church. It reports the consecration act of the monastery in honour of St. George, carried out by the two bishops Otto of Bamberg and Hartwig of Regensburg. The inscription plate specifies the year of the act and, by implication, its own date as 1119 (•MCXVIIII•). It was made of baked clay, painted over in an alternating, red white pattern, and is approximately 26 cm wide, 41 cm high and 3 cm thick, with a crack running through its entire breadth. The sunk letterforms are the classical capitalis monumentalis or Roman square capitals. Copies are at display in several German museums, including the Gutenberg Museum at Mainz. The unusual sharpness of the inscription letters has long led epigraphists to believe that they were not carved by hand into the clay. The typographic character of the inscription was demonstrated in a systematic examination of the text body by the typesetter and linguist Herbert Brekle. His findings confirm that the text was produced with a printing method similar to that of the Phaistos Disc: The 17-line text was created by pressing individual, pre-formed stamps (probably made of wood) into the soft clay in a way that, for each letter which occurred more than once, the same letter stamp was re-used, thereby producing identical imprints throughout the text. Thus, the essential criterion for typographic text production was met, namely the repeated use of identical types for a single character.
