The artist William Hogarth portrayed a "longitude lunatic" in the eight scene of his 1733 work "A Rake's Progress". Twenty years later, though, Hogarth described John Harrison's H-1 chronometer as "one of the most exquisite movements ever made." Later, members of the Lunar Society of Birmingham called themselves "lunaticks". In an age with little street lighting, the society met on or near the night of the full moon.
