La Celestina

The Tragicomedy of Calisto and Melibea (Spanish: Tragicomedia de Calisto y Melibea), known in Spain as La Celestina, is a work entirely in dialogue published in 1499. Sometimes called in English The Spanish Bawd, it is attributed to Fernando de Rojas, a descendant of converted Jews, who practiced law and, later in life, served as an alderman of Talavera de la Reina, an important commercial center near Toledo.

The book is considered to be one of the greatest works of all Spanish literature and is even the single topic of a Spanish literary journal, Celestinesca. La Celestina is usually regarded as marking the end of the medieval period and the beginning of the renaissance in Spanish literature. Although usually regarded as a novel, it is written as a continuous series of dialogues and can be taken as a play, having been staged as such and filmed.
