Emblem of the 22nd degree of the Ancient and Accepted Scottish Rite in the 1893 Vermont publication.
The degree of “Knights of the Royal Axe of the Grand Patriarchs, Princes of Libanon” in the Baylot collection of degrees, state that the L on the sword (above, the Hebrew “lamed”) stands for “Libanon”. The S (top right, “Shin”) for “Sidonian” and the N (“noun”) for “Noah”.
Also (some versions of) Memphis Misraim has a 22nd “Knight of the Royal Axe” degree with a plainer axe as emblem as the one above.
