2nd-century artifacts

The Coligny calendar is a bronze plaque with an inscribed calendar, made in Roman Gaul in the 2nd century CE. It lays out a five-year cycle of a lunisolar calendar, each year with twelve lunar months. An intercalary month is inserted before each 2.5 years. The lunar phase is tracked with exceptional precision, adjusted when necessary by a variable month, and the calendar uses the 19-year Metonic cycle to keep track of the solar year. It is the most important evidence for the reconstruction of an ancient Celtic calendar.

The Taurobolic Altar (French: Autel taurobolique) is an inscribed ancient Roman altar found in 1704 in a vineyard belonging to a certain Bourgeat on the Fourvière hill in Lyon, France.

It is now held at the Gallo-Roman Museum of Lyon.
