In late medieval and early modern Europe, armour was more than a defensive technology for war or knightly sport. Its diverse types formed a complex visual language. Luxury armour was fitted precisely to a wearer's body, and its memorable details declared his status. Empty armour could evoke an owner's physical presence, prompting recollection of knightly personae, glittering pageantry, and impressive feats of arms. Its mnemonic power persisted long after the battle had ended, the trumpets had gone silent, and the dust had settled in the tournament arena. Previously believed to contain preliminary designs sketched by master armourers, the Thun-Hohenstein album is a bound collection of drawings by professional book painters depicting some of the most artistically and technologically innovative armours of the fifteenth and sixteenth centuries. Like a paper version of the princely armories that first formed during the 1500s, the album's images offered rich sites of meaning and memory. Their organization within the codex suggests the images' significance to their compiler. At the same time, the composition and details allow the reader to trace the transmission of recognizable armours, and the memories they embodied, from the anvil to the page.
