Today's episode serves as an "epilogue" to the series on Biblical etymology. "Secular," of course, means "unaffiliated with religion," but originally, it was a word used to describe the measurement of long spans of time. Roughly equivalent to a century, the "saeculum," as it was known in Ancient Rome, was celebrated with pagan rituals, theater, and games. Pagan rituals ... how ironic. Over the course episode, we trace its development from antiquity to the 19th century philosophical movement.
