Félix Arturo Lope de Vega (1562–1635) was a playwright and poet during Spain’s literary Golden Age and known for his prodigious output. He wrote some 3,000 sonnets, three novels, four novellas, nine epic poems, and about 1,800 plays. This manuscript, known as the Daza Codex, is a signed draft, written by Lope between 1631 and 1634, near the end of his life. It is not a book in itself but a cartapacio misceláneo (miscellaneous notebook) that belonged to the Duke of Sessa, Lope’s patron and first collector. The last 96 pages are bound in upside down. The contemporary binding, in parchment, presents on the cover, as a title, the following note in ink: "Here are the eclogues," thus indicating the contents, which are mainly poems on pastoral themes, although some prose is also included. The notebook includes both unpublished works and fragments of several known works. The latter include La Dorotea (Lope’s main prose work, an extensive dialogue that he preferred to call "action in prose," published in 1632), and "Amarilis, huerto desecho" (Amarilis, abandoned kitchen garden). The works are interspersed in the manuscript, indicating Lope's method of creating several pieces at one time.
