Freemasonry symbolism in 1628 painting, of Flanders (modern-day Belgium)

What imagery?

Many people have a wrong perception of the Freemasons the idea that they’re some unreachable secret society. In reality, anyone can apply to join a lodge, and there’s public, online information about Freemasonry and its international lodges.

his style was very typical of the Flemish Baroque period. The compass and globe here are classic Renaissance/Baroque symbols

And yeah, a lot of well educated and influential people were Freemasons back then, so naturally you see those symbols pop up in art from the period.
