1. Story
2. Work starts on the cathedral on the Ile de la Cite. Its nave becomes one of the earliest large-scale applications of the flying buttress - though whether the flyers are original to the 12th-century campaign or belong to a later alteration has been argued for more than a century, because the fabric has been rebuilt enough to blur the evidence.

19. Evidence
20. Photoelastic model studies of Gothic structures arguing that wind loading on the high roof and clerestory, rather than vault thrust alone, was a principal design driver for flying buttresses, and that upper flyers are best explained as wind bracing. V55 verification basis: real and widely cited; not read in this session, and the argument is summarised here from its reception rather than from the text.
