Propertius published a first book of love elegies in 25 BC, with Cynthia herself as the main theme; the book's complete devotion gave it the natural title "Cynthia Monobiblos". The "Monobiblos" must have attracted the attention of Maecenas, a patron of the arts who took Propertius into his circle of court poets. A second, larger book of elegies was published perhaps a year later, one that includes poems addressed directly to his patron and (as expected) praises for Augustus. The 19th century classics scholar Karl Lachmann argued, based on the unusually large number of poems in this book and Propertius' mention of "tres libelli", that the single Book II actually comprises two separate books of poetry conflated in the manuscript tradition, an idea supported by the state of the manuscript tradition of "Book II." An editor of Propertius, Paul Fedeli, accepts this hypothesis, as does G.P. Goold, editor of the Loeb edition.
