Seven years seem anciently to have been, all over Europe, the usual term established for the duration of apprenticeships in the greater part of incorporated trades. All such incorporations were anciently called universities, which, indeed, is the proper Latin name for any incorporation whatever. The university of smiths, the university of tailors, &c. are expressions which we commonly meet with in the old charters of ancient towns. When those particular incorporations, which are now peculiarly called universities, were first established, the term of years which it was necessary to study, in order to obtain the degree of master of arts, appears evidently to have been copied from the term of apprenticeship in common trades, of which the incorporations were much more ancient. As to have wrought seven years under a master properly qualified, was necessary, in order to entitle any person to become a master, and to have himself apprentices in a common trade; so to have studied seven years under a master properly qualified, was necessary to entitle him to become a master, teacher, or doctor (words anciently synonymous), in the liberal arts, and to have scholars or apprentices (words likewise originally synonymous) to study under him. By the 5th of Elizabeth, commonly called the Statute of Apprenticeship, it was enacted, that no person should, for the future, exercise any trade, craft, or mystery, at that time exercised in England, unless he had previously served to it an apprenticeship of seven years at least; and what before had been the bye-law of many particular corporations, became in England the general and public law of all trades carried on in market towns. For though the words of the statute are very general, and seem plainly to include the whole kingdom, by interpretation its operation has been limited to market towns; it having been held that, in country villages, a person may exercise several different trades, though he has not served a seven years apprenticeship to each, they being necessary for the conveniency of the inhabitants, and the number of people frequently not being sufficient to supply each with a particular set of hands.
