This crown is from a German 1st/2nd degree tracing board of the “Andreasloge” of the Strikte Observanz. A reference to King Solomon? It also appears on a triangle, on an inverted triangle and for example in the emblem of the Order of the Amaranth, an aligned order for daughters of Freemasons.
Detail from Feddersen D/93, p. 427, I think from around 1770.
