Sealing on a tag
Sealing on a tag was one form of appended sealing,
the other form of appended sealing being on a tongue.
Appended sealing contrasted with applied sealing.
For sealing on a tag or tags, the duplex cauda,
the parchment was first turned up at the bottom (plica),
a slit cut in the plica, and a double strip of parchment slipped through
the plica. The seal was then placed on the parchment strips, the tags.
Such a fashion was the most usual way of sealing charters, although seals on tongues
were employed on some charters in the early twelfth century. Royal charters were
sealed on silk cords or laces, but that process is unusual for private charters.
The seal exhibited here is a vesica seal or pointed oval. Seals of private charters
were normally in green wax.
