A Broken Chain
In the medieval ages, a chain was often used as a metaphor for what kept the soul in the body. The broken chain found on tombstones represents the soul being freed from its physical shell. If the chain is unbroken and if it features the letters FLT (for Friendship, Love, and Truth), it probably means the deceased belonged to the Independent Order of Odd Fellows.
