: We question the claim, common since Duhem, that sixteenth century astronomy, and especially the Wittenberg interpretation of Copernicus, was instrumentalistic rather than realistic. We identify a previously unrecognized Wittenberg astronomer, Edo Hildericus (Hilderich von Varel), who presents a detailed exposition of Copernicus's cosmology that is incompatible with instrumentalism. Quotations from other sixteenth century astronomers show that knowledge of the real configuration of the heavens was unattainable practically, rather than in principle. Astronomy was limited to quia demonstrations, although demonstration propter (...) quid remained the ideal. We suggest that Osiander's notorious preface to Copernicus expresses these sixteenth century commonplaces rather than twentieth century instrumentalism, and that neither `realism', nor `instrumentalism', in their modern meanings, apply to sixteenth century astronomy.

When Giovanni Boccaccio undertook to compile the myths of Greco-Roman antiquity in the mid-fourteenth century, he was working within a long tradition of medieval commentaries on Ovid's mythological works and mythographical compendia, such as Alberic of London's De deis gentium. His Genealogie deorum gentilium libri, on which he worked until the final years of his life, also falls within the traditions of biblical exegesis and of philosophical commentary on texts, such as Boethius's De consolatione philosophiae and Virgil's Aeneid. The complex (...) and eclectic nature of Boccaccio's learning, however, along with the antimodern organizational structure of the treatise, has led to the underestimation of its importance in the history of medieval and Renaissance approaches to ancient myth. As Charles Osgood's partial translation of the work demonstrates, the focus of critics has been limited to the final two books of the treatise, in which Boccaccio defends both poetry and his work from detractors. The fourteenth and fifteenth books of the Genealogie have been by far the most long-lived sections of the work. The straightforward defense of poetry through recourse to the topos of the poeta theologus places the work in a historical continuum that leads from Albertino Mussato and Francesco Petrarca to Coluccio Salutati, Marsilio Ficino, and Angelo Poliziano, not to mention the poetic theorists of the English Renaissance, such as Sir Philip Sidney.
