Within our cemeteries, it is common to find among different symbols objects that may reflect either the profession of the buried person, or act as a reference to their affiliations or membership (i.e. Freemasonry). They may also represent their hobbies, leisure or fields of interest.
A mask or, more commonly, two masks would symbolise the world of theatre/ drama. Found on a grave, it is usually associated with comedians and actors.
The two masks together are known as the Sock and Buskin.
The sock and buskin are two ancient symbols of comedy and tragedy. In Greek theatre, actors in tragic roles wore a boot called a buskin (Latin cothurnus) that elevated them above the other actors. The actors with comedic roles only wore a thin soled shoe called a sock (Latin soccus).
