Via Masonic Traveller
Of the many emblems of Freemasonry, none is more iconic that the lambskin apron. Alien outside of the lodge, under the tiled lodge it represents the totality of what it means to be a Mason. It’s said to be more noble than the Roman Eagle or the Golden Fleece, the Masonic apron is literally, the badge of a mason carried with him into the next existence.
