Above, below, or around her — which, she could not tell — was a vast stone hall, with so many staircases, balconies, windows, and doorways at different heights and odd angles to each other that she had no idea what was up or down, near or far, inside or out, backward or forward. Planes reversed themselves as you watched them, receding corners suddenly jutted out, rising steps inverted themselves, floors became ceilings, and walls turned into precipices. In this room, it seemed that the law of gravity had been repealed, and perspective had seven dimensions. If there had been water, it would have seemed to flow uphill. She felt sick and giddy, and had to cling to a pillar to remain upright.
