Seen from Mr. Witanoont’s Vinegar-Yard, Bedlam’s center looked as if a squarish funnel had been turned upside-down and clapped on top of it. The broad part of the funnel was a high mansard roof enclosing the ample space in which Daniel, Isaac, and Saturn were now standing. The narrow nozzle was the cupola, which pierced the ceiling, admitting sky-light and (as its windows were ajar) exhausting the fouled air of the asylum. "This was Hooke’s favorite part of the building, his ærie and his atelier, " Daniel said, "though it then looked much different." He approached a railing and gazed down into the central well that vented cupola-light into the entrance hall. "This had planks thrown across it, making it into one great floor, uninterrupted."
