Henry VIII, not satisfied with six wives, had maintained any number of mistresses, storing them, when not in use, in a sort of bolt-hole on the top of a hill above Greenwich Palace. His successors had not shared his appetites, and so the royal fuck-house had largely fallen into ruin. The foundations, however, were still sound. Atop them, Wren and Hooke, working in a hurry, and on a tiny budget, had built some apartments, which served as plinth for an octagonal salt-box. Atop that was a turret, an allusion in miniature to the Norman turrets of the Tower of London. The apartments were for Flamsteed to live in. The octagon above was constructed essentially so that the court-fop contingent of the Royal Society would have a place to go and peer learnedly through telescopes. But because it had been built on the foundations of Henry VIII's hilltop love shack, the whole building was oriented the wrong way. To make real observations, it had been necessary to construct an alienated limestone wall in the garden out back, oriented north–south. This was partly sheltered by a sort of roofless shack. Bolted to it were a pair of Hooke-designed quadrants, one looking north and the other looking south, each equipped with a sighting-tube. Flamsteed's life, thereafter, consisted of sleeping all day, then going out at night, leaning against this wall, peering through the sighting-tubes at stars swinging past, and noting their positions. Every few years, the work was enlivened by the appearance of a comet.
