"The Natural History of Ireland" by Philip O'Sullivan Beare is an important source of the history of Ireland's natural environment and its political history. It was originally written in Latin by Don Philip O'Sullivan Beara, an Irish nobleman living in exile in Spain. He wrote the "Zoilomastix" in order to refute "Topographia Hiberniae", written by Giraldus Cambrewsis, which was very derogatory of Ireland and the Irish people. It was still the accepted text on Ireland in the Seventeenth Century which angered Philip O'Sullivan as it contained so many inaccuracies in its description of Ireland."Book One of the Zoilomastix" highlights his reaction to these propagandist texts denigrating Ireland and comments on the natural habitat and features, such as rivers, plants, animals, fish and birds, of Ireland. Species listed are named in four languages, including Irish. An introduction by Denis O'Sullivan gives an overall history of the O'Sullivan's and Philip in particular. This book has never been translated into English before, thus making this a completely unique publication. This translation is both faithful to the original and accessible to the general reader.
The ability to deal with a complex, multilingual manuscript of this kind is now rare and it is to the credit of the author that this is such a readable edition of the text. This translation constitutes an important contribution to scholarship pertaining to O'Sullivan Beare, early modern Irish Latin literature and Irish history in general.
