I agree. For example when looking at the Elizabethan Era poets, playwrights, and authors wrote about issues and events that pertained to what was going on during that time. The event shown in their pieces shows people of this generation how people thought during that time and how they handle different situations. The same goes for culture. Looking at work from a generation shows how times have changed and how humans have changed.
For your question, it is needed cite it. So the answer is Yes. The quotation should be followed by the author's name and a page reference in parentheses. It is for you to give credit to the author and to avoid from getting a plagiarized work.
