The logo came from a dream in 2016.
Four elements arranged around a fifth: the island.
Four years later, Vincent Desiderio found the same symbol carved into stone in a corner of the auditorium -made by a 19th-century inmate.
We don't know what it means, or if it means anything.
But it's there.
And it's been there for over a century.
Odd thing to find after four years of using a symbol you thought you invented in a dream.
Make of that what you will.
