The term tassel in Freemasonry refers to a decorative element that is often associated with the tessellated border surrounding the tracing board of an Entered Apprentice. This border is traditionally depicted as a cord adorned with tassels, symbolizing the bond of love and unity among Masons. The tassels are typically located at the corners of the border and are interpreted to represent the four cardinal virtues: temperance, fortitude, prudence, and justice.
Historically, the tassel was part of a cord that encircled the symbols of the Order marked on the floor during initiation ceremonies. Over time, the original term indented tassel evolved into tassellated border and eventually tessellated border, which is now commonly used to describe this symbol. The tassels thus serve as a reminder of the ethical principles that bind the fraternity together.
