Did you know?

From their noun basileus, meaning “king,” the Greeks derived the adjective basilikos meaning “royal.” In ancient Thera there was a public building called “Basilike stoa,” or Royal portico, and it may have been the prototype of later Roman basilicas. The first of these was built in 184 ce, and by the time of Augustus, there were five basilicas in the vicinity of the forum. They were used for public assembly, transacting business, and judicial proceedings. When the first Christian churches were built, they were often modeled after the civil basilicas.
