Pêro da Covilhã

Born around 1460 in the mountain town of Covilhã in Portugal’s Beira Interior, Pêro da Covilhã was a polyglot royal squire, undercover intelligence agent, diplomat, and overland explorer. Serving two monarchs—Dom Afonso V and Dom João II—he executed the most ambitious espionage mission of the fifteenth century: mapping the Indian Ocean spice network and locating the Christian realm of Prester John a full decade before Vasco da Gama set sail.

Following the death of King Afonso in 1481, his son and successor, King Dom João II, appointed Pêro a squire of the Royal Guard (escudeiro da Guarda Real) and dispatched him undercover into Castile to track exiled noble conspirators. Two delicate missions to Barbary followed: first to negotiate a treaty of peace and friendship with the Sultan of Tlemcen, and second to the Sultanate of Fez ostensibly to purchase purebred Berber horses for the young Duke Dom Manuel. Having proven his linguistic skill and resourcefulness, Pêro was chosen in May 1487—alongside Afonso de Paiva—for the King’s supreme covert mission to the East: Pêro was to trace the spice trade to its source in the Indies and chart the maritime routes thither; Afonso was to locate the legendary Prester John.

The two agents traveled across Spain and the Mediterranean to Rhodes. Disguised as Muslim merchants they continue to Alexandria, Cairo, and the Red Sea before parting ways at Aden in 1488: Pêro sailed the monsoon to the Malabar Coast of India, the Persian Gulf, and down the East African coast to Sofala, while Afonso struck out for Ethiopia. Afonso never arrived at their agreed rendezvous in Cairo in late 1490, However, two secret royal couriers did: Rabbi Abraham of Beja and José Zapateiro of Lamego, They brought new orders from King João II: Pêro was to send his Indian Ocean intelligence home, escort the Rabbi to Hormuz, and find Prester John himself if this had not already been done.

The Year-of-Birth Debate

  • According to Álvares, when Pêro returned from Seville to Portugal at the outbreak of the War of the Castilian Succession in May 1475, Don Juan de Guzmán presented him to King Afonso V as a moço de esporas (“spur-boy” or youth groom). In the fifteenth-century Portuguese court hierarchy, the rank of moço was reserved for adolescents roughly twelve to fifteen years of age—hardly a twenty-five-year-old man. Born around 1460, Pêro would have entered service in Seville as a boy page of nine or ten (age of greatest language aptitude, explaining his native-level command of Castilian and Arabic), returned to Portugal at fifteen, and earned his promotion to escudeiro (squire) on campaign just in time to fight at the Battle of Toro (March 1476) at sixteen—the exact same age at which Prince Dom João II himself had been knighted in battle at Arzila five years earlier.
  • A birth date around 1460 also confirms the stage of his life in Abyssinia. When the Portuguese embassy departed Ethiopia in 1526, Álvares described an active, sharp-minded nobleman in his mid-sixties who rode alongside the departing envoys and entrusted them with one of his young sons. In the temperate mountain air of the Ethiopian highlands—where his royal patron, Empress Regent Eleni, lived to roughly ninety—a resilient survivor like Covilhã could plausibly have lived into his eighties, witnessing the devastating invasion of Imām Aḥmad ibn Ibrāhīm al-Ghāzī (“Gragn”) and the decisive Portuguese-Ethiopian victory near Lake Tana at the Battle of Wayna Daga (1543).
  • Lifelong Exile in Abyssinia
    Covilhã spent the final decades of his life at the imperial court of Ethiopia, forbidden by the custom of the country ever to leave, and died there without direct communication with Portugal.
  • The Covert Nature of His Missions
    Unlike the celebratory maritime voyages of Vasco da Gama, every mission Covilhã undertook—from tracking noble traitors in Castile to reconnoitering the spice ports of Malabar—was clandestine intelligence work never intended for public disclosure.
  • Censorship, Dynastic Politics and the 1755 Catastrophe
    During the critical decade between Covilhã’s arrival at Calicut (1488) and da Gama’s voyage (1498), King Dom João II enforced a strict Policy of Secrecy (Política de Sigilo) to outmaneuver Castile during the Treaty of Tordesillas negotiations. Under his successor, King Dom Manuel I, that secrecy was repurposed to elevate Manuel as the sole architect of the “Discoveries” at Dom João’s expense—and whatever original dispatches or maps survived in Lisbon’s royal archives were later incinerated in the Great Lisbon Earthquake and fire of 1755.
  • A Handful of Surviving Chronicles
    Outside of a single eyewitness account, our knowledge of Covilhã rests on a handful of early chronicles and one nineteenth-century biography—all housed in my research library and detailed under Sources: the contemporary royal chronicles of Rui de Pina (who cryptically records him as “Joham de Covilhaã”) and Garcia de Resende; the sixteenth-century histories of João de Barros (Décadas da Ásia), Castanheda, and Damião de Góis; and the untranslated 1898 biographical study by the Conde de Ficalho.

The Account of Álvares

Pater Francisco Álvares accompanied the embassy of Rodrigo de Lima to the Preste João—as the Portuguese continued to call the Negus of Abyssinia. The mission arrived in 1520 and stayed until 1526. The relation of Father Álvares about the country is the holy grail of information on Pêro da Covilhã. Álvares was not only his contemporary, but met him in person at the Court of the King of Kings. Covilhã had accomplished all his missions for the Portuguese King and had become a highly valued advisor at the Abyssinian court, but was not permitted to leave the country.

Francisco Álvares relation Ho Preste Joam das Indias

The approach of the Portuguese ambassador to the Abyssinian court probably didn’t quite look like that of the title-page picture. Emperor Dawit II, better known as Ləbnä Dəngəl, lived in a great tent encampment like the emperors before him. And there were no such buildings as depicted.

There are two excellent English translations of Father Francisco Álvares’ work:

  • Narrative of the Portuguese Embassy to Abyssinia during the years 1520–1527 by Lord Stanley of Alderley, published 1881 by the Hakluyt Society, London.
  • The Prester John of the Indies, a revised edition of Lord Stanley’s work, by C. F. Beckingham and G. W. B. Huntingford, published 1961 in two volumes also by the Hakluyt Society, Cambridge.

Álvares mentions Pêro da Covilhã often throughout his book and devoted an entire chapter to him. Below is the complete verbatim text of this chapter from Lord Stanley’s translation (please note that I have not changed a single word or the spelling, but the division of the text into paragraphs is mine):
