Gulielmus Laurus, a recusant exile and neo-Latin poet from Yorkshire has left a variety of evidence for his existence from 1587 through to the late 1590s, mostly in published verse in which he reflects on his life and experience, protests against the Anglican settlement, and asserts his faith. The article attempts to piece together his biography from the meagre information he gives, and offers two alternative interpretations of the data: one in which he was born around 1565, and one, marginally preferable, which makes him about ten years older. His poems are highly personal documents which reveal his interactions with the ‘republic of letters’ in Belgium, Germany and France, and the intense practical and psychological pressures of life as a friendless exile.
