All inscriptions of the altarpiece were written in Latin. The font of the dedicatory inscription is overall classified as Gothic capitalis. Modern commentators agree that the inscriptions were produced by hammering individual
letter punches one by one into the silver plate. Evidence for this typographic method can be derived from the observation that the
letterforms comply with the criterion of
type identity according to which every letter imprint must come from one and the same letter punch. The type identity is
inter alia evident in the repeated occurrence of the faulty letter "R" throughout the text that indicates a damaged letter punch. The
high relief letters stand proud in rectangular recesses created by the bases of the
low relief punches; the fine edges between these recesses are a further indication of the sequential use of individual letter punches. The smaller ones were used for the names of the saints and the donor's inscription of the patriarch, while the names of the archangels, of the Mother of God, the abbreviations of sanctus/sancta ("holy") and the two-line inscription were printed with the larger set. However, a random check with the
Limburg Staurotheca which dates from this period showed that the inscription was
engraved directly into the metal. The
Prüfening dedicatory inscription of 1119 is another early example of typographic text production in the Latin West. It differs in some technical details though: its plate is made of
clay, not silver, and the inscription was created in low relief with (wooden) stamps, not metal punches. == References ==
