By 1200 AD, medieval European lapidaries had developed the art of seal engraving, creating intricate gemstone seals for nobility and clergy. These seals served both practical purposes, such as authenticating documents, and decorative functions, showcasing the craftsmanship of the era. The practice of seal engraving reflects the importance of identity and status in medieval society, as well as the technological advancements in gem cutting and artistry.

The medieval European seal engraving practices around 1200 influenced heraldic symbolism in chivalric romances and poetry. Poets like Sir Gawain and the Green Knight utilized these symbols to convey themes of honor and identity, enriching the narrative depth of their works.
