Roman roads have lasted for millennia and were key to its military might

A look at what was on the menu for ancient Romans

"Delicious Italy" is a website exploring the food culture of various Italian cities and regions, and in this article, the editors explore what is known about the diet of ancient Romans.

Ancient Romans sometimes lobbed insults through graffiti

Graffiti was used to communicate ideas, offer advice, and, not unlike the internet, talk some trash. That was especially true with tourists, who sometimes scrawled messages on the pyramids, including one person who complained, "I can not read the hierogylphics." In response, someone replied, "Why do you care that you can not read the hieroglyphics? I do not understand your concern."

A medieval Italian visits Constantinople

In the tenth century, the Holy Roman Emperor Otto I sent Liudprand of Cremona, an Italian bishop, to Constantinople on a diplomatic mission. He was not successful. But the very undiplomatic report he sent back to the emperor about his experiences provides a unique – and often very entertaining – look at life and ceremony in the Byzantine capital, dramatically different from anything in Liudprand’s Italy.

For centuries, European aristocrats made travel a rite of passage

Starting in the 16th century, young English aristocrats mounted “Grand Tours” of Europe. Accompanying tutors provided lessons in the continent’s architecture, art, history, and literature.
