Answer:
This is a quotation from Chapter XXV of the First Part of "Don Quijote", by Miguel de Cervantes Saavedra.
Step-by-step explanation:
Don Quixote is telling Sancho that as he imagines the farmer’s daughter, Aldonza Lorenzo, as his princess. Dulcinea del Toboso is not of noble lineage, but she is beautiful and virtuous. We never actually meet Dulcinea. She does not even know of Don Quixote’s patronage. Don Quixote says that poets praise ladies that may not even exist, but his praises make Dulcinea real. She exists in fame and in the imagination of everyone who reads about her. Don Quixote’s narrations take on the force of reality.
