Focusing on four poets who because of their distinctive profiles illustrate especially well the opportunities and pitfalls of writing science poetry during the long eighteenth century Four Augustan Science Poets: Abraham Cowley, James Thomson, Henry Brooke, Erasmus Darwin offers numerous close readings that shed light not only on standard versions of the sublime but also on these idiosyncratic variants: the apologetic (Abraham Cowley), the illicit (James Thomson), the perverse (Henry Brooke) and the atheistic (Erasmus Darwin). Recurrent concerns include the similarities and differences among the languages of poetry, science and religion. Of the poets analyzed all but Thomson wrote extensive notes to accompany their lines, permitting further comparison of languages, in this case between the same authors’ poetry and prose.
