Mackey's Revised Encyclopedia of Freemasonry, Volume 1 (New Edition, Revised and Enlarged), Comprising the whole range of Arts, Sciences and Literature of the Masonic Institution. Mackey knew that very "few men have the means, time, and the inclination for the purchase of numerous books, and for the close and attentive reading of them...to acquire a knowledge of all matters connected with the science, the philosophy, and the history of his Order." It was this thought that suggested to him that he should collect materials for a work which under one cover might help to enlighten his Brethren. This book is so absorbing you could sit and read it from cover to cover. It also serves as a handy reference guide for any Masonic question that may arise.
Albert Gallatin Mackey was a medical doctor and Freemason who served as Grand Lecturer and Grand Secretary of The Grand Lodge of South Carolina, as well as Secretary General of the Supreme Council of the Ancient and Accepted Scottish Rite for the Southern Jurisdiction of the United States.
