Ancient Coins Of Rome, 1st Century BC

Such a wide sampling of history and territory covers many rather disparate cultures and periods. "Classical antiquity" typically refers to an idealized vision of later people, of what was, in Edgar Allan Poe's words, "the glory that was Greece, the grandeur that was Rome!" In the 18th and 19th centuries reverence for classical antiquity was much greater in Western Europe and the United States than it is today. Respect for the ancients of Greece and Rome affected politics, philosophy, sculpture, literature, theatre, education, and even architecture and sexuality.
In politics, the presence of a Roman Emperor was felt to be desirable long after the empire fell. This tendency reached its peak when Charlemagne was crowned "Roman Emperor" in the year 800, an act which led to the formation of the Holy Roman Empire. The notion that an emperor is a monarch who outranks a mere king dates from this period. In this political ideal, there would always be a Roman Empire, a state whose jurisdiction extended to the entire civilized world.
Epic poetry in Latin continued to be written and circulated well into the 19th century. John Milton and even Arthur Rimbaud received their first poetic educations in Latin. Genres like epic poetry, pastoral verse, and the endless use of characters and themes from Greek mythology left a deep mark on Western literature.
In architecture, there have been several Greek Revivals, (though while apparently more inspired in retrospect by Roman architecture than Greek). Still, one needs only to look at Washington, DC to see a city filled with large marble buildings with façades made out to look like Roman temples, with columns constructed in the classical orders of architecture.
