It is well known that at one time Abyssinia was, so far as the Emperor’s power extended at that period, converted to Roman Catholicism by the instrumentality of Portuguese missionaries. The connection with Portugal commenced in 1499, when Pedro Covilham penetrated by way of the Mediterranean and the Red Sea, to Shoa, where the Emperor then held his court. He was well received. An ancient Ethiopian law decreed that no foreigner who reached Abyssinia should be allowed to leave the country, but Covilham was permitted to send home an account of his experiences. At a later date a further communication from the traveller induced the Portuguese Government to despatch an embassy, which, after many privations and adventures, arrived in Shoa in October, 1520. It brought no presents, and was not cordially welcomed. However, the Emperor desired to send an answer to the King of Portugal, and therefore—in defiance of the ancient usage—allowed the ambassador to return to Lisbon, taking with him an Ethiopian envoy. But certain of the Portuguese were detained in Abyssinia, among whom was a priest named John Bermudez. Some years later this man was appointed Abouna, or Patriarch, on the death of the incumbent of that office. He made his way to Rome, where Pope Paul III. confirmed his title, and he thence proceeded, in accordance with the Emperor’s desire, to Portugal, and solicited the aid of European troops to assist the Abyssinians in repelling the Mohammedan invasion which then threatened the country. The Portuguese Government despatched an expedition of some four hundred men under Don Christopher de Gama. These troops disembarked at Massowah in 1542. In an engagement with the Mohammedan forces on August 30 of that year the Abyssinian allies took to flight, and the Portuguese were surrounded. They cut their way through the enemy and effected their retreat, but Don Christopher, who had been wounded, was captured by the enemy and murdered by the Mohammedan commander. His skull was sent to Constantinople as a trophy. The surviving Portuguese besought of the Emperor an opportunity to avenge their leader, and they shortly afterwards took part in an action in which the Mohammedan forces were routed with great slaughter. These circumstances added to the influence of Bermudez, but he insisted rigorously on the complete acceptance of Roman doctrine and ritual by the Abyssinians, and thus incurred the resentment of the Emperor. As a consequence he lost the advantages which he and his compatriots had gained, and finally abandoned his task and quitted the country, embarking at Massowah, where he had landed. A subsequent mission under the leadership of Oviedo, Bishop of Hieropolis, which reached Massowah in 1558, failed equally, after many adventures—including an Abyssinian Council at which the Emperor and the bishop publicly and heatedly disputed about points of doctrine—and in 1560 Oviedo received orders from Rome to withdraw from Ethiopia and proceed to Japan.
