When the Scottish poet Thomas Pringle emigrated to the Cape Colony in 1820 he voyaged also into a new creative life and an art responsive to his colonial home, "sterner verse" for "darker scenes". Accompanying him to the Cape, the sonnet became his most consistent choice for capturing his experiences and convictions, his personal crises and the greater trauma of colonial appropriation and racial oppression. In this study his unique contribution to the Romantic-era sonnet is for the first time given its full due, through readings that are as attentive to form and formal agency as to the cultural, social and historical conditions in which they are enmeshed. Moving beyond colonial theory to consider issues of literary migration, this illuminating work shows how Pringle effectively opened up a radical conversation between the habitual modes of perception and response of British Romanticism and his new, southern world.
