Invention of the Degrees of Freemasonry

We would be kidding ourselves if we believed that the Masonic lodge experience of today is the same as the experience when Speculative Freemasonry began, or in the days of the old Operative Freemasons. Albert Mackey provides us with a detailed explanation of how we evolved from a one degree operative system of Freemasonry into the three craft lodge degrees of today. This is an important work for any student of Freemasonry.
