AbstractThis essay explores the relationship between an early modern exile and his native environment, as depicted in Philip O'Sullivan Beare's unfinished natural history Zoilomastix. Writing by turns in Latin, Spanish and Gaelic from the safety of the Habsburg court, O'Sullivan Beare marshalled Ciceronian rhetoric and Plinian wonder to argue for the conservation of interwoven natural and cultural environments. One of the earliest examples of national historiographies written from exile by erudite Irish figures, Zoilomastix has most often been read in terms of its political theology. Though understandable, such readings obscure O'Sullivan Beare's idiosyncratic treatments of self, state and nature. Additionally, such readings only partially consider the author's attempts to engage with the debates on ethnicity, natural law and resource capture which directed the actions of the English state. Adopting the dialogic framework of Mikhail Bakhtin's chronotope, this essay therefore explores the extent to which the genre of natural history was utilized to inform and influence contested narratives. It argues that O'Sullivan Beare's autobiographical account, and its relevance to the forthcoming ‘loss’ of his Gaelic world, has much to tell us in a time of ecological crisis.
