Roman Legal Witnesses Identified by Their Teeth
Some Roman legal documents weren't sealed with a signature—they were stamped with a bite mark.

A Toothmark Instead of a Signature
Some Romans signed official documents by biting into soft wax. Their dental imprint stood in for a written signature—proof they had agreed.
Why Bite the Wax?
Many people in Rome, especially slaves and women, couldn't write their names. To confirm their identity, they'd press their teeth into a wax seal at the end of a contract. Roman legal writers mention this—it's a practice straight from the archives, not a myth.
Romans who couldn't write would literally sink their teeth into wax to sign contracts, leaving a unique dental imprint. Archaeologists have found wax tablets and legal texts describing this method—your smile, immortalized as identification. For many, this was more binding than a written name.
