Zaga Christ ( – April 22, 1638), also referred to as Ṣägga Krəstos, Atənatewos, and Lessana Krəstos, was an Ethiopian imposter who falsely claimed he was a Prince of Ethiopia. He traveled extensively, living in Sudan, Egypt, Palestine, Greece, Italy, and France. As part of a vetting process to prove his identity he produced an autobiography detailing his dynastic claim and his travels. This is the earliest known autobiography written and published in Europe by an African-born author. Zaga Christ eventually converted to Catholicism, and while residing in Turin, he was immortalized by the accomplished artist Giovanna Garzoni (1600–1670) in what is considered the earliest known European portrait miniature of an African. Zaga Christ died of pleurisy in 1638 while living in France under the patronage of Cardinal Richelieu.

Accounts of his story There are many accounts of his life story. The French Franciscan friar Eugène Roger met Zaga Christ in Nazareth (then part of Ottoman Empire) and was familiar with his whereabouts from there until his death.F. Eugene Roger, La Terre Sainte, ou, Description topographique tres-particuliere des Saints Lieux, & de la Terre de Promission, Paris: Antoine Bertier, 1664 Rèchac's accounts came from an Italian manuscript, written by Zaga Christ himself when he was living in Rome. The Catholic Patriarch of Ethiopia, Afonso Mendes, devoted a letter in 1638 to disputing his claims of royal birth.

Early Age In March 1632, Zaga Christ arrived at the Venetian consulate in Cairo, claiming to be the son of Emperor Yaʿǝqob I of Ethiopia, who had been killed during the political and religious conflicts of the early 17th century. According to his account, he had fled from Ethiopia through the Nile Valley (Funj Sultanate) after Emperor Susǝnyos I, the ruling Catholic monarch, had allegedly killed his father. Zaga Christ's story intrigued the consulate's chaplain, Father Paolo da Lodi, who had served as the prefect of the Franciscan mission in Egypt. Recognizing the potential value of Zaga Christ as a symbol of Catholic interests in Ethiopia, Paolo informed his superiors at the Congregation of Propaganda Fide in Rome.

Shortly after meeting him, Father Paolo sent a message to Rome mentioning "a certain Abyssinian who claimed to be the son of the king of Abes [Ethiopia], though he misled many, including myself, as I could not communicate with him in his language." However, Father Paolo’s endorsement was initially undermined when three Ethiopian pilgrims informed Capuchin Gilles de Loches that he was a "liar" and a "rogue." Persuaded by these accusations, Father Paolo retracted his earlier support, warning Rome and Jerusalem to disregard his previous letters. Nevertheless, his opinions began to shift again as he spent more time with the young Ethiopian upon taking up his new post in Jerusalem.

Father Paolo eventually became convinced of his authenticity, reporting that the Ethiopian had impressed friars in Jerusalem and Nazareth with his humility, piety, and "royal soul." This change of heart came after his formal conversion to Roman Catholicism on St. Peter's Day, a significant moment that reinforced his claims of noble lineage and religious devotion. Conversion was a critical tool for it helped to align himself with Roman authority and presented him as a potential Catholic ally in Ethiopia. Father Paolo arranged for Zaga Christ's passage to Rome, providing a glowing endorsement of him as the son of the Ethiopian emperor, filled with zeal for the Catholic faith. This letter remained the most fervent endorsement Zaga would receive during his European journey. In Jerusalem, Ṣägga Krәstos was hosted at the Ethiopian monastery of Dayr as-Sulṭān, located on the roof of the Church of the Holy Sepulchre.

In Europe After spending time in Jerusalem and Nazareth, Zaga departed from Haifa in September 1632. His journey took him through various Venetian-controlled territories before arriving in Otranto, Italy. During his travels through the Kingdom of Naples, he was treated with considerable respect, receiving gifts and honors from local nobles and viceroys, including valuable horses and financial support. However, despite such high regard, suspicions about his true identity persisted. The papal nuncio in Naples notified Rome that Zaga Christ lacked sufficient credentials, a challenge that would continue to follow him throughout his stay in the Eternal City.

Upon reaching Rome in early 1633, Zaga Christ faced increasing scrutiny. His reception as a prince was contested by certain factions, including Jesuits and Portuguese who were wary of Franciscan influence and fearful that he was a fraud attempting to exploit the Church. These factions alleged that the Franciscans were misled and that the presence of Zaga Christ was damaging to the Church. The situation became tense, with the Portuguese Jesuits likely involved in the Vicar of Rome’s decision to confine Zaga Christ to the Franciscan convent and pressure him to leave the city. The same royal family who would attempt multiple conquests of Ethiopia (See: Italo-Ethiopian War would bankroll and back Sagga's claim.

His presence in Rome occurred amidst broader tensions between religious orders, the papacy, and the Portuguese crown. The Congregation of Propaganda Fide, which oversaw global Catholic missions, was engaged in a power struggle with the Portuguese over control of ecclesiastical privileges in overseas territories. The Jesuits, who had been instrumental in the missionary efforts in Ethiopia, were particularly concerned about the Congregation’s centralizing ambitions and Zaga Christ arrival in Rome. His backers, such as the Franciscans, saw his potential as a symbol of an alternative Ethiopian mission.

Despite this conflict, Zaga Christ managed to gain the protection of Francesco Ingoli, the secretary of Propaganda Fide, who reported that the Ethiopian prince had "the appearance and manners of a royal." Although Ingoli was inclined to support Zaga Christ, he required solid proof of his identity. Ingoli, a scholar and scientist, began a thorough investigation, gathering testimonies and cross-referencing Zaga Christ claims with known Ethiopian history. However, the task was complicated by the limited available information about Ethiopia’s dynastic politics.

A key piece of evidence during this investigation was a lengthy autobiographical statement written by Zaga Christ, titled Narratione del viaggio fatto dall’Altezza Seren(issima), del sig. Zagra Cristos figliolo dell’Imperator d’Ethiopia. This document, which was later printed and circulated in Europe, presented his version of his lineage and life events, including a detailed recounting of Ethiopia’s dynastic struggles. However, although the account displayed an impressive understanding of Ethiopian history, it also contained significant chronological errors. Zaga Christ extended Emperor Yaqob reign by two decades, a necessary revision to support his claim as the emperor’s son. Historical records showed that Yaqob reigned only briefly from 1597 to 1607, a discrepancy that cast doubt on Zaga Christ assertions.

Zaga Christ certainly shared his statement with the Italian historian Maiolino Bisaccioni, who met him in Venice in the first half of 1634. Bisaccioni later included the first printed version of the Narratione in his 1634 study of the Thirty Years' War. Like other observers, Bisaccioni was impressed by the young man's bearing and character, describing his meeting with him as follows:"This past 1st of December a young Ethiopian arrived in Venice, famed to be of the imperial lineage of that vast and big kingdom that controls multiple kingdoms. It is not my purpose to describe such remote things, already narrated by many others. I will only say what attracted my curiosity. I saw and learned from him happenings worthy of being recorded. I saw the youth, nineteen or twenty years old, of a colour between black and olivaster, of very beautiful appearance, with sparse facial hair, with very black and curly hair, and of medium height; I found him to be of good wit, well versed in the holy scriptures, very devout, affable, majestic, and melancholic because of his accidents, he made stunted sighs. He politely told me of his affairs: there is no bigger fall for a great prince than to go as a pilgrim, poor, wander and flee between accidents and disasters. Hence, I decided to honour my papers and, in the most succinct way possible, describe them [his affairs] here’"Despite these qualities, doubts persisted. Ingoli continued to gather evidence, including testimonies from individuals who had encountered Zaga Christ during his journey. However, none of the testimonies were conclusive enough to fully verify his claims. Affidavits from interpreters and merchants in Cairo offered little more than hearsay, and even the supporting statements from prominent Maronites failed to provide definitive proof of his imperial lineage. Although Ingoli remained skeptical, he allowed him to remain under the care of his Franciscan supporters.

Despite his efforts, Ingoli had limited evidence regarding his claims, primarily relying on the latter’s narratives. He reorganized the original Narratione into a chronological table titled Brevissima narratio del imperatore Jacob disposta per ordine d’anni, outlining calendar years, claimed ages, and key events. While this suggests he was likely an impostor, Ingoli overlooked this due to his unfamiliarity with Ethiopia’s dynastic history.

In his reports, Ingoli questioned how the Church should handle the situation, given the lack of certainty about his identity. He hesitated to endorse him officially but believed support was essential for the future of Catholicism in Ethiopia. Ingoli recognized that Ṣägga Krǝstos could be either an asset or a liability, depending on his true identity and how he was treated.

Ingoli considered various European powers for potential support. He dismissed Spanish-Portuguese backing due to existing tensions and avoided the Venetians because of concerns over their relations with the Ottomans. The French seemed viable, but he worried it could provoke conflict in Ethiopia. Ultimately, he suggested the Duchy of Tuscany because of its ties to the Druze Emir Fakhr al-Din, who had received European support for his own ambitions.
