Historically, the Old Charges fall into three groups. The first comprises the two earliest versions, the Regius MS of c.1390 and the Cook MS of c.1420...The second, and largest, group begins with the Grand Lodge No. 1 MS, dated 25 December 1583, and covers all the versions datable before the formation of the premier Grand Lodge in 1717. The third group comprises manuscript and printed versions produced after 1717, the majority of which appear to have been produced as antiquarian curiosities.
