This work is a study of two Neo-Latin poems of the 17th century: René Rapin's Hortorum libri IV, dealing with contemporary French garden architecture, and Cowley's Plantarum libri VI, in which the plants are personified and botanical information is embedded in various mythological and historical narratives. The author examines both the subject matter and the formal characteristics of the two poems. Her textual analysis focusses in particular on their use of classical models.
