Heading to Berlin to talk about the Prize Papers at the Institute for Asian and African Studies at Humboldt University.

Looking forward to show some cool Prize Papers letterlocking techniques!

Letters sent to lieutenant D'Alban, ship's captain and member of the Masonic Lodge of Batavia. We see a nonagon-shaped letterpacket, 1798:

@kubikpixel @bkoehn https://www.bbc.com/future/article/20210616-how-the-forgotten-tricks-of-letterlocking-shaped-history It seems to me like letter locking should also be included in encryption history. The tamper resistant folds and interlocking spirals are interesting. #LetterLocking #encryption

On Friday I will be speaking of watermarks and letterlocking in the missives sent from the castle of Raseborg in 1389-1521. The paper is part of the annual seminar of SKAS, the Spciety of Medieval Archaeology in Finland (in Finnish). #Raseborg #medieval #histodons #watermarks #letterlocking #missives #communication #scribes #15thCentury #informationmanagement #Tallinn #Finland

#Letterlocking beauties in the archive today: one letter from Charles II to the Duke of Mazarin sealed with blue ribbon & red wax, & another from Henrietta Maria also to DoM sealed with black wax & hair (? I think - maybe horsehair?)

early end to end encapsulation

letterlocking was used as a tamper-evident closing of a letter by using folds, cuts and glues to make it difficult to snoop undetected

Not really encryption, but still a lot more work than GPG encrypting something
