Meaning ‘language of the coasts’ in Arabic, Swahili emerged in East Africa many centuries ago through contact with the wider Muslim world. Although the language is most often linked with Kenya and Tanzania, Swahili was also used as a lingua franca as far north as Somalia and as far south as Mozambique—a country whose name derives from that of a fifteenth century Muslim ruler, Musa Bin Mbiki. In this episode, we explore the little-known history of Swahili in Mozambique, where the language became a rich poetic vehicle of religious teachings. After an overview of Swahili under the Portuguese rulers and the sultans of Angoche, we take a closer look at performances of the Nazajina, an epic poem recounting the last days of the Prophet. Finally, we zoom back out to the big picture by asking how Mozambiquan Swahili helps us rethink the notion of ‘world literature.’ Nile Green talks to Clarissa Vierke, author of On the Poetics of the Utendi: A Critical Edition of the Nineteenth-Century Swahili Poem “Utendi wa Haudaji” (Lit, 2011).
