Step-by-step explanation:
The city that was previously known as Lutetia during the Roman period is modern-day Paris. Lutetia was a Roman city located in the region that is now the central part of France. Remarkably, the city held significant importance during Roman times and had a temple to Apollo built by Emperor Augustus. Moreover, the pastoral festival of Lupercalia was celebrated here to avert evil spirits and promote purification, health, and fertility. Ancient Roman cities, such as Timgad and Pompeii, provide extensive archaeological insights into Roman life. Although not all cities from the Roman era have been preserved as extensively as Pompeii, which was buried and subsequently excavated, Lutetia has nonetheless left its historical mark in what is now a bustling global capital.
