To hold a merry meeting, with noise and riot, but without doing injury to anyone. It seems generally, if not always, to include the idea of a wasteful use of food, and of intemperate use of strong drink. According to the first orthography, the term may have formed from gild, a society, a fraternity, and the verb to ravage, or from French ravager, the riotous meeting of a gild or fraternity. Could we suppose that the proper pronunciation were guleravage, it might be derived from French gueule, the mouth, the throat, also the stomach, conjoined with the verb already mentioned; to waste ... to gormandize.--John Jamieson's Etymological Scottish Dictionary, 1808
Add Strong Drink to the Autumn Diet
In Via Recta: The Right Way of Living (1650), Thomas Venner recommended the following dietary changes: "In October and November, and likewise after the middle of September, according as you shall find the season to alter, you may begin to arme your body with stronger drinks against the cold of the ensuing winter, and to feed more liberally, and on stronger meats."
Full of wholesome advice, that Via Recta. I think I'll arme my body with some tea later this morning.
