Spotlight: Intact metal book clasps

Posted by

·

Cataloguing this 18th century book of proceedings against witchcraft, sorcery and evil, was an almost spell-binding experience for me (excuse the pun!) because it has intact metal clasps. Coming across unbroken metal clasps was exciting for me because often the metal clasps on rare books are damaged, not functional, or have been lost, sometimes leaving only scraps of leather ties behind.

In the early modern period, book clasps like these held the covers (also known as ‘boards’) of a book together, keeping it closed and protecting the pages from light and dirt. This book from the Heythrop Library’s collection shows how clasps also helped to preserve a book’s shape and keep its pages flat, even after hundreds of years. Often, the shape of books will change and warp over time due to handling, humidity, temperature etc.

These metal clasps are attached to leather bands that are fastened
to the lower board (back cover). On the lower board, you can see how the
leather bands have gold pins keeping them secured to the board. The metal clasps
themselves each have a pierced hole that fits over the corresponding metal peg attached to the upper board (front cover). Click
