The city thrums with voices.
September 1, ancient Rome. The city’s calendar marks dies comitialis—a day when the people’s assembly gathers. Citizens pour into the Forum, ready to haggle, heckle, and vote on new laws, alliances, or trials.
No deals behind closed doors today.
On a dies comitialis, all public business was fair game. Senators held court beneath the basilica’s cool arches. Messengers darted through crowds, scrolls unfurling with news and accusations. A city where talk alone could set new fates in motion.
On a dies comitialis, Romans could vote, argue, and reshape the city’s future. The Forum roared with voices from dawn until dusk.
