Dąbrowski has an unidentified “Masonic Symbols”, see below. The image itself says: “Templar Chart” so I suppose these are symbols from Templar degrees.
In the middle, just below the men, you see two pillars with two different vessels on them. My guess is that the book in the middle (Bible?) is connected.
Dąbrowski P. 168. Year and designer unknown. A very similar (but not identical) image can be found on http://www.freemasons-freemasonry.com/TBs.html (accessed 24/7/24). This is a certificate with description: “Phoenix Temple of Honor, 1870”.
