The Ancient Landmarks of Freemasonry: What They Are, Who Listed Them, and Why the Lists Disagree

Overview
The Ancient Landmarks are the fundamental principles that no Grand Lodge may change. The 1723 Constitutions required that they be preserved but never listed them. Albert Mackey later proposed twenty-five and Roscoe Pound seven, and American Grand Lodges still differ on which list, if any, they have adopted.
This guide traces the word from Proverbs to the 1723 General Regulations, then sets Albert Mackey’s twenty-five landmarks of 1858 against the criticism of Roscoe Pound, Albert Pike and others. It shows how far American Grand Lodges disagreed, using a 1954 Masonic Service Association survey and the short Massachusetts list as examples. It explains where landmarks matter most today, in the standards for recognising other Grand Lodges, and gives a simple way to tell a landmark from Grand Lodge law and lodge custom. It closes with the mistakes to avoid and practical steps for finding your own Grand Lodge’s position.
