The instrument was worked in the following manner. Should a devout person desire to keep a Lady Fast, he or she repaired to the church to determine by the aid of the wheel which of the days or anniversaries should be observed. Thereupon the sexton took the wheel, which he either hung up or held at arm's length by means of a ring at the termination of the handle. He then set the wheel in motion, and the votary, standing by, caught at the strings as they spun round. Whichever string was caught decided the question on what day the fast was to be begun, whether on the feast of the Annunciation or that of the Assumption, or any other of the six feasts, or days of the week, of which the several strings were emblematical. The feast of the Assumption was known as Lady Day in Harvest, being observed on the fifteenth of August.
The compromise, which we style the Reformation, at first inclined to the retention of the Saturday fast; and, indeed, the legislature interfered to enforce its more regular observance. In 1548 a remarkable measure was enacted with this object, not so much, it is to be feared, out of any genuine concern for religion as for the benefit of the fishing community, whose interests had been injuriously affected by recent ecclesiastical changes.
"Albeit," it recites, "the King's subjects now having a more perfect and clear light of the Gospel and true word of God, through the infinite cleansing and mercy of Almighty God, by the hand of the King's Majesty and his most noble father of famous memory, promulgate, shewed, declared and opened, and thereby perceiving that one day or one kind of meat of itself is not more holy, more pure, or more clean than another, for that all days and all meats be of their nature of one equal purity, cleanness, and holiness, and that all men should by them live to the glory of God, and at all times and for all meats give thanks unto Him, of which meats none can defile Christian men or make them unclean at any time, to whom all meats be lawful and pure, so that they be not used in disobedience or vice; yet forasmuch as divers of the King's subjects turning their knowledge therein to satisfy their sensuality, when they should thereby increase in virtue, have in late time more than in times past, broken and contemned such abstinence which hath been used in the Realm upon the Fridays _and Saturdays_, the Embering days, and other days commonly called Vigils, and in the time commonly called Lent and other accustomed times: the King's Majesty, considering that due and godly abstinence is a means to virtue, and to subdue men's bodies to their soul and spirit, and considering also especially that Fishers, and men using the trade of living by fishing in the sea, may thereby the rather be set on work, and that by eating of fish much flesh shall be saved and increased, and also for divers other considerations and commodities of this realm, doth ordain 'that all statutes and constitutions regarding fasting be repealed, but that all persons neglecting to observe the ordinary fast days--Fridays, _Saturdays_, Ember days, and Lent--be subject to a fine of ten shillings and ten days' imprisonment for the first offence.'"
