The coat of arms attributed to Satan is Gules a fess Or between three frogs proper, which appears painted in the folio of a mediæval manuscript known as the Douce Apocalypse, created in England c. A.D. 1270. The arms are inspired by chapter 16, verse 13 of the Book of the Revelation of Saint John, which reads, as quoted from the Douay–Rheims translation, "And I saw from the mouth of the dragon, and from the mouth of the beast, and from the mouth of the false prophet, three unclean spirits like frogs."
As Satan is often given the rank of prince, twice referred to as the "prince of this world" in the Gospel According to Saint John, known as the "prince of the power of this air" in the Epistle Of Saint Paul to the Ephesians, described as being the Prince of the Grigori in the Second Book of Enoch, his arms are presented here in the same fashion of a sovereign prince, the crown that of a German fürst.
