It has been put forward that Roman lead pipe inscriptions were created by movable type printing, but this view has been recently dismissed by the German typographer Herbert Brekle.
The essential criterion of type identity was met by medieval print artifacts such as the Latin Pruefening Abbey inscription of 1119 that was created by the same technique as the Phaistos disc. The silver altarpiece of patriarch Pellegrinus II (1195−1204) in the cathedral of Cividale was printed with
