Step-by-step explanation:
After the fall of the Western Roman Empire, certain cultural achievements were lost, such as aqueducts, coins, and literacy. However, Latin, the language of the educated and of the Church, continued to have a significant influence on the languages that arose post-Empire and was used in liturgies and ceremonies. Another lasting achievement was the Julian calendar, which remained the mainstream method of timekeeping until it was reformed into the Gregorian calendar.
