John II. had sent to Cairo two learned Jews to await the arrival of Covilham, and to one of these, the Rabbi Abraham Beja, the traveller gave his notes, the itinerary of his journey, and a map of Africa given to him by a Mussulman, charging Beja to carry them all to Lisbon with the least possible delay. For himself, not content with all that he had done hitherto, and wishing to execute the mission which death had prevented Paiva from accomplishing, he went into Abyssinia, where the "negus" or king, known by the name of Prester John, flattered by seeing his alliance sought by one of the most powerful sovereigns of Europe, received him with the greatest kindness, and gave him a high position at his court, but to make sure of retaining his services, he constantly refused him permission to leave the country. Although he had married there and had some children, Covilham still longed for his native country, and when, in 1525, a Portuguese embassy, of which Alvares was a member, came into Abyssinia, he witnessed the departure of his countrymen with the deepest regret, and the chaplain of the expedition has naively re-echoed his complaints and his grief. M. Ferdinand Denis says, "By furnishing precise information upon the possibility of circumnavigating Africa, by indicating the route to the Indies, by giving more positive and extended ideas upon the commerce of these countries, and above all, by describing the gold-mines of Sofala, and so exciting the cupidity of the Portuguese, Covilham contributed greatly to accelerate the expedition of Gama."
