Note 14 — PART I. THE POET’S DREAM.

“The internal columns are placed twenty-four feet apart, while the external ones have no more than eight feet (a third of twenty-four) of separation; while the distance between each of the transept columns is three times twenty-four, or seventy-two feet. This also is the width of the middle aisle of the building: the side aisles are forty-eight wide, and the galleries and corridors twenty-four. Twenty-four feet is also the distance between each of the transverse gutters under the roof; hence the intervening bars, which are at once rafters and gutters, are necessarily twenty-four feet long.”
