Saturn was a Roman god and the namesake for the planet and Saturday. These columns and pediment were part of the Temple of Saturn. It was first built in 497 BC. This version is from the 4th century AD. Inside used to be the Aerarium treasury where the republic’s riches were stored. This seems appropriate because Saturn was associated with wealth and plenty during his reign in the Golden Age. This mythical period was characterized by utopian peace, harmony and prosperity for all of mankind.
