The Constitutions of the Free-Masons, Containing the History, Charges, Regulations, &C, of That Most Ancient and Right Worshipful Fraternity, for the Use of the Lodges – Hunter, William (PDF)
First published in 1723, The Constitutions of the Free-Masons (often called Anderson's Constitutions) is the foundational document of modern symbolic Freemasonry. Compiled by James Anderson under the direction of the Grand Lodge of England, it transformed Masonry from a guild of working stonecutters (operative) into a philosophical and social society (speculative).
