Sannazaro was one of the neo-Latinists working at the end of the fifteenth and beginning of the sixteenth centuries. Influenced by Virgil, but also Ovid, Propertius, Tibullus and Catullus, Sannazaro wrote epic, elegies and epigrams. The elegies and epigrams, especially, demonstrate his reception of classical erotic elegy, as well as Catullus. He is probably most famous to English scholars for his Arcadia, which served as the model for Philip Sidney's own 'old' Arcadia.
Michael Putnam's translations are smoothly rendered in prose, with copious scholarly notes. This whole series is beautifully produced for the price, on good paper and with nice hardbacks.
Neo-Latin poetry is often more interesting for its role in the transmission of classical texts than as poetry in its own right, and that might be the case here. It's still good, however, to be able to afford what has to be an uncommercial volume.
