Dąbrowski has an unidentified “Masonic Symbols”, see below. The image itself says: “Templar Chart” so I suppose these are symbols from Templar degrees.
A rose also features in Royal Arch symbolism and can there be found in the middel of a cross and/or a reference to Sharon.
A single rose can also be seen in the emblem of the Women’s Grand Lodge of Belgium. Roses also seem to feature in the apparel of the Women’s Grand Lodge of France.
There is a specific meaning for the rose in Freemasonry proper (“sub rosa”), but I suppose the significance here is another.
In more general (Masonic) terms, a rose can stand for beauty or the aim for ‘higher living’.
A rose also appears on an Adoption apron.
(top) Dąbrowski P. 168. Year and designer of the chart are 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”.
(bottom). Reproduced here and there. Can sometimes be found on auctions. Given as coming from the 19th century, but lodges of adoption were already active in the 18th century.
