Where it comes from
From Ceres (a famous asteroid and dwarf planet), + -ium. The element was discovered and named in 1803. It was named after the asteroid, which had been discovered recently (1801) and had been named after Ceres, the Roman goddess of agriculture. This was during an era when asteroids were culturally exciting things that humans were just beginning to understand properly in astronomical terms, and the era also featured a fascination with neoclassical themes and thus naming things after icons of ancient Greek and Roman mythology and literature.
