Flitch of bacon custom sites and the Dunmow flitch is referred to in Chaucer. The awarding of a flitch at both sites seems to have been an exceedingly rare event. The Dunmow tradition was revived in Victorian times, largely inspired by a book ("The Flitch of Bacon") by William Harrison Ainsworth. Flitch trials are still held in modern times at Great Dunmow. A counsel is employed to cross-examine the nominated couples and attempt to show they are undeserving of the award. There is evidence that the flitch of bacon tradition existed outside Britain in mainland Europe and some would push its origins back as
Flitch beam construction. Glulam beams were used to support the second floor and the roof. This allowed the appearance of wooden columns, while providing the necessary strength. The method for calculating the size of a flitch beam to be used in construction is straightforward, using the transformed-section method. The steel piece of the beams is imagined to be an equivalently flexible (although much thicker) piece of wood. This allows the elasticity of the entire beam to be calculated as if it were entirely made up of wood. There is modest business activity involving flitch beams with The Timber Research and Development Association
