There are a number of masonic manuscripts that are important in the study of the emergence of Freemasonry. Most numerous are the "Old Charges" or "Constitutions". These documents outlined a "history" of masonry, tracing its origins to a biblical or classical root, followed by the regulations of the organisation, and the responsibilities of its different grades. More rare are old hand-written copies of ritual, affording a limited understanding of early masonic rites. All of those which pre-date the formation of Grand Lodges are found in Scotland and Ireland, and show such similarity that the Irish rituals are usually assumed to be of Scottish origin. The earliest Minutes of lodges formed before the first Grand Lodge are also located in Scotland. Early records of the first Grand Lodge in 1717 allow an elementary understanding of the immediate pre-Grand Lodge era and some insight into the personalities and events that shaped early-18th-century Freemasonry in Britain.
