A ledger line refers to the parallel lines incised or sculpted around the edge of the top surface of a mediaeval ledger stone (tombstone), laid flat on the floor of a church or on top of a chest tomb (or "altar-tomb"), within which lines is inscribed an epitaph or simple biographical memorial text, generally in gothic script and in Latin.
The phrase "inscribed on a ledger line" is commonly found in the writings of English antiquaries.
