Archaeologists have found part of a seal that probably belonged to archbishop Petrus Philippi who died 1341.
Seals were used instead of signatures during the Middle Ages in order to authenticate documents, as well as for sealing documents or packaged.
When Philippi died in 1341, the stamp was most likely destroyed right after his death. "That was done to prevent people from impersonating the bishop by using his seal”.
It seems not much has happened in 700 years. Identity theft is an even bigger problem now. ;-)
