The word gothic has a long and conceptually twisty history in English. The Goths were one of many Germanic peoples who invaded the Roman empire around the third century, and for centuries afterward their name was a synonym for barbaric, warlike, or crude behavior. (Shakespeare plays on these two meanings in the first scene of Titus Andronicus, when a character who is an actual Goth looks back with longing at a time “when Goths were Goths.”) In the 17^th century, the word gothic became associated with Teutonic culture more generally, eventually providing the name for a style of medieval architecture that originated in northern Europe.
