A new era of church building began in the late 14th century when the wool trade made East Anglia one of the richest counties of England.  Rebuilding campaigns were everywhere and the roofs became great statements of power and aspirations.  The roof is up among the angels, and angels (all nine choirs of them) became major objects of devotion.  The parish churches developed a great tradition of timber hammerbeam roofs with eloquent figures of angels floating out over the populace.  Dorothy Sayers's mystery, The Nine Tailors, is set in this area and has an angel roof as a major character.  H. Munro Cautley, who was engaged in the repair of many East Anglian roofs and examined them from scaffolds, bared and even dismembered in the case of major repairs, states that his admiration was “increased by a fuller knowledge of the carpenter’s skill.  It is amazing to find no trace of iron bolts, straps, or mails.  The most elaborate structures rely on framing alone, the various parts being merely morticed and tenoned together and fixed with wooden pins.”  (Suffolk Churches (1982), 89).
