In the 1630s, a young traveller by the name of Ṣägga Krәstos (1616–38) crisscrossed Italy and France, claiming to be the heir of the late Ethiopian Emperor Yaʿǝqob and pledging to return to Ethiopia at the helm of a Catholic mission. While in Rome, intent on convincing the papacy of his identity, he authored a lengthy autobiographical statement that included a precise dynastic claim, an account of his father’s rise and demise, and an itinerary of his own journey from Ethiopia to Rome. Later, as he continued his journey, Ṣägga Krәstos shared his statement with his European acquaintances; once in Paris, he published it, dedicating it to Anne of Austria, Queen of France. This article sketches the contours of Ṣägga Krәstos’s journey and identity and offers a comprehensive genealogy of the autobiographical statement’s many extant versions. It also discusses the transfiguration that both his reputation and statement underwent after his death. Ṣägga Krәstos’s is the earliest known autobiography voluntarily written and published in Europe by an African-born author. Following this article is a complete annotated translation – the first in the English language – of what is likely to be the earliest extant version of the statement, followed by excerpts from later versions. A complete transcription of the source is available with the online supplementary materials published with this article.
