Besides the famous double headed eagle and the eagle with a crown, Masonic symbolism also features an eagle proper.
The 21th degree (‘Knight of the Rose Cross’) of the Mirecourt collection, describes the eagle as “the symbol of the supreme being”.
Fairly frequent in old ritual texts is a black eagle. There are several rituals of degrees called “Chevalier de l’Aigle Noir” (‘Knight of the black Eagle’) with variations to the name (and degree).
