Assuming then that the freemasons of the present day are the sole inheritors of the system arranged at the so-called "Revival of 1717," which was a development from an operative body to one partly speculative, and that, so far back as the MS. Records extend and furnish any light, they must have worked in Lodges in secret throughout the period noted, a history of Freemasonry should be mainly devoted to giving particulars, as far as possible, of the lodges, their traditions, customs and laws, based upon actual documents which can be tested and verified by members and non-members alike. It has been the rule to treat, more or less fully, of the influence exerted on the fraternity by the Ancient Mysteries, the Essenes, Roman Colleges, Culdees, Hermeticism, Fehm-Gerichte _et hoc genus omne_, especially the _Steinmetzen_, the Craft Gilds and the Companionage of France, &c.; but in view of the separate and independent character of the freemasons, it appears to be quite unnecessary, and the time so employed would be better devoted to a more thorough search after additional evidences of the activity of the craft, especially during the crucial period overlapping the second decade of the 18th century, so as to discover information as to the transmitted secrets of the medieval masons, which, after all, may simply have been what Gaspard Monge felicitously entitles "Descriptive Geometry, or the Art and Science of Masonic Symbolism." The rules and regulations of the masons were embodied in what are known as the _Old Charges_; the senior known copy being the _Regius MS._ (British Museum Bibl. Reg. 17 A, i.), which, however, is not so exclusively devoted to masonry as the later copies. David Casley, in his catalogue of the MSS. in the King's Library (1734), unfortunately styled the little gem _A Poem of Moral Duties_; and owing to this misdescription its true character was not recognized until the year 1839, and then by a non-mason (Mr Halliwell-Phillipps), who had it reproduced in 1840 and brought out an improved edition in 1844. Its date has been approximately fixed at 1390 by Casley and other authorities. The curious legend of the craft, therein made known, deals first of all with the number of unemployed in early days and the necessity of finding work, "that they myght gete here lyvynge therby." Euclid was consulted, and recommended the "onest craft of good masonry," and the genesis of the society is found "yn Egypte lande." By a rapid transition, but "mony erys afterwarde," we are told that the "Craft com ynto England yn tyme of good kynge Adelstonus (AEthelstan) day," who called an assembly of the masons, when fifteen articles and as many more points were agreed to for the government of the craft, each being duly described. Each brother was instructed that-- "He must love wel God, and holy Churche algate And hys mayster also, that he ys wythe."
