Old Mortality was a Scottish stonemason of the 18th century, who late in life decided to travel around Scotland re-engraving the tombs of 17th century Covenanter martyrs. The narrator describes meeting Old Mortality, hearing his anecdotes, and finding out other stories of the events to present an unbiased picture, such as a weapon show held in 1679 by Lady Margaret Bellenden, shooting at the popinjay, fighting with mounted infantry, the Battle of Drumclogand and many more.
