What are the Ancient Landmarks and who defined them?

The Ancient Landmarks are the immemorial usages and unchangeable fundamental principles that define the fixed identity of Freemasonry 1. The term first appeared in print in George Payne's Regulations of 1721, published in the 1723 Book of Constitutions 1. In early lodge practice, the Book of Constitutions itself or the ritual were sometimes referred to as the Landmarks 1. Jurists later defined them as universal, unrepealable fundamentals existing from time immemorial, without which the fraternity would cease to be itself 1.

Albert G. Mackey was the first Masonic scholar to distinctly enumerate and format a comprehensive list 1. In October 1858, he published twenty-five Landmarks in the *American Quarterly Review of Freemasonry*, later incorporating them into his *Text Book of Masonic Jurisprudence* 1. Mackey's list was officially adopted or endorsed by about half of the Grand Lodges in the United States, though it drew criticism for claiming to be immemorial and for its specific length 1. Prior to publication, Theodore Sutton Parvin urged Mackey to reduce the list to five or six items 1.

No single authoritative list is universally accepted across all jurisdictions 1. Alternative definitions were proposed by numerous scholars: Chetwode Crawley reduced the Landmarks to three core tenets 1; William J. Hughan defined them as unalterable pre-Grand Lodge regulations 1; Woodford set down eighteen 1; and the Rev. George Oliver proliferated hundreds divided into twelve classes 1. J. W. Horsley established five indispensable Landmarks—belief in a personal God, belief in a future life, the Volume of the Sacred Law, secrecy, and the modes of recognition—while noting that makers of such lists often overlook the high grades, such as the Scottish Rite 1.

Grand Lodges have also framed their own lists. In 1918, the Grand Lodge of Massachusetts adopted seven Landmarks, specifying monotheism, belief in immortality, the Volume of the Sacred Law, the Legend of the Third Degree, secrecy, operative symbolism, and adult male membership 1. Variations also exist regarding degree structures: while the division into three degrees is widely considered a Landmark, Mackey observed that the disruption of its final teaching led to differences between the Royal Arch in English, Scottish, Irish, and American systems 1. In 1813, the Grand Lodge of England declared Ancient Craft Masonry to consist of three degrees, including the Holy Royal Arch 1.

Disagreement over the number of Ancient Landmarks stems primarily from the fact that early Masonic authority never defined or enumerated them 2. The thirty-ninth General Regulation of 1723 required Grand Lodges to preserve the old landmarks, yet left the unwritten common law of the Craft uncodified 2. Because no single global governing body exercises authority over Freemasonry, each Grand Lodge remains self-governing and holds sovereign authority to define, interpret, or codify its own standards according to the Grand Lodge of British Columbia and Yukon.

Masonic jurists and scholars have long expressed divergent opinions regarding what constitutes a genuine landmark 1. In Craft Masonry, Albert C. Mackey published a influential list of twenty-five landmarks in 1858, which was officially endorsed or adopted into written law by about half of North American Grand Lodges 12. However, Mackey's list faced immediate and persistent criticism 1. Scholars such as Theodore Sutton Parvin argued for reducing the list to five or six, while Albert Pike sought to refute Mackey's points in the Iowa Grand Lodge Proceedings of 1888 1.

Proposed lists vary wildly in length based on individual criteria. Chetwode Crawley identified three basic landmarks, J. W. Horsley listed five indispensable principles, and Rev. George Oliver expanded his list into hundreds 1. A 1907 survey of Grand Lodges by C. F. Catlin found that twenty-one jurisdictions enacted no legislation on the subject, choosing to leave landmarks as unwritten law, whereas legislating jurisdictions adopted anywhere from 10 to 75 distinct landmarks 1.

Jurisdictional context also drives these differences. As Sir Alfred Robbins noted, the existence of dozens of independent Grand Lodges in North America created a far greater need to debate and codify landmarks as a shared platform for mutual recognition than existed under British Grand Lodges 1.

Ancient Landmarks are defined within Masonic jurisprudence as unchangeable and unrepealable principles that cannot be altered by any Masonic authority 1. In Craft Masonry, the thirty-ninth General Regulation of 1723 established that while a Grand Lodge possesses inherent authority to enact new regulations or amend existing ones for the fraternity, it must do so provided always that the old Landmarks are carefully preserved 32.

Albert G. Mackey identified the unalterable nature of these principles as a crowning Landmark in itself 1. Under this doctrine, even if every Masonic authority across the world were to unite in a Universal Congress, they would lack the prerogative to enact, alter, or abolish a Landmark 1. Any proposed change that would transform Freemasonry into something else is classified not as a legitimate alteration, but as an unallowable innovation 1.

Although the central legend of the Temple Builder remains preserved across all regular Masonic systems, historical variations arose in how different Orders structured their final teachings 1. In Craft Masonry, the English Grand Lodge affirmed in 1813 that Ancient Craft Masonry comprised three degrees including the Holy Royal Arch, whereas the high degrees of the Scottish Rite and continental systems developed distinct modes of leading the candidate to the final lesson of Symbolic Masonry 1.

In modern practice, Grand Lodges maintain this prohibition against altering fundamental standards. The Regional Grand Lodge of Northern India states that bye-laws, regulations, and powers framed by the Masonic body must not be contrary to or inconsistent with the Landmarks, and that it is an essential duty to observe the antient usages, customs, and Landmarks of the Order rather than alter them.
