Migil de Castanhoso served as a scribe on the Portuguese expedition to Abyssinia from 1541-1543, a historical odyssey he meticulously recorded in his seminal work 'The Portuguese Expedition to Abyssinia.' While the precise details of his early life remain sparse, Castanhoso's legacy endures through his eyewitness account, serving as an invaluable resource for historians studying early-modern Portuguese expeditions in Africa. His narrative stands out for its rich detail and embodies the essence of 16th-century Portuguese literature, filled with descriptions of military campaigns, diplomatic exchanges, and the cultural intricacies of the Ethiopian empire. Although not as widely known as some of his contemporaries, Castanhoso's contribution to the literature of exploration and colonial encounter holds significance. His recordings bear the hallmarks of the 'chronicle' literary style; a genre devoted to the factual, yet vivid recounting of events, which was prevalent among writers documenting new geographical discoveries and colonial ventures of the period. Castanhoso's work echoes the humanism of the Renaissance, reflecting on the broader implications of cross-cultural interactions during an era of European expansion.
