From the article: "Lauren Caldwell’s tribute to Giovanni de’ Dondi’s 1364 Il Tractatus Astarii, the first famous Astrarium, which is a mechanical planetarium that mimics the paths of the stars and planets. In other words, it's an astronomical clock. Archimedes used a primitive model, but the first real working astrarium clock is credited to de Dondi. The backpiece here is the Mercury Wheelwork."
