Similarly to Craft Freemasonry, the Mark Degree conveys moral and ethical lessons using a ritualised allegory based around the building of King Solomon's Temple. The events of the degree require the candidate to undertake the role of a Fellowcraft, thus the degree is seen as an extension of the Fellowcraft Degree. The legend reconciles the Anglo-American version of the Hiramic legend with the 3,300 Master Masons of Anderson's constitutions, making them Mark Masters, or overseers. The candidate is helped to choose a Mason's mark, and thereby introduced to another extension of the Hiramic myth, relating to the manufacture, loss, and re-finding of the keystone of the Royal Arch of that degree. The link between the degrees of Master Mason, Mark Master Mason and the Royal Arch is further demonstrated in the Order of Royal and Select Masters. An explanation of Mark Masonry and its history can be found here.
