This is the plaque that Fergus Whelan posted on the stair tower at the Church on Mary Street (a religious building now operated as a bar and restaurant). The plaque honors Francis Hutcheson, “Father of the Scottish Enlightenment,” whose ideas made their way into the US Declaration of Independence.
The plaque’s coverings catch refections of the buildings across the intersection, at the west end of Henry Street. Here you see Primark’s world headquarters (the lovely red brick building with the patina-ed copper dome) to the right of Francis’ likeness.
