Barros (_Decade I_, i, 2) tells us a story, probable enough, about the inception of the Infant's plans of discovery. He relates how one night, after much meditation, he lay sleepless upon his bed, thinking over his schemes, till at last, as if seized with a sudden access of fury, he leapt up, called his servants, and ordered some of his _barcas_ to be immediately made ready for a voyage to the south along the coast of Marocco. His court was astonished, and attributed this outburst to a divine revelation. It was natural enough--the resolution of a man, weary with profound and anxious thought, to take some sort of decisive action, to embark without further delay on the realisation of long-cherished schemes. To summarise the course of the Prince's life, from 1415, before entering on any discussion of special points: After the Conquest of Ceuta he returned to Portugal; was created Duke of Viseu and Lord of Covilham (1415), having already received his knighthood at "Septa"; and began to send out regular exploring ventures down the West Coast of Africa--"two or three ships" every year beyond Cape Non, Nun, or Nam. In 1418 he successfully went to the help of the Governor of Ceuta against the Moors of Marocco and Granada.[5] On this second return from Africa, when in 1419 he was created Governor of the Algarve or southmost province of Portugal, he is supposed by some to have taken up his residence at Sagres,[6] near Cape St. Vincent, and to have begun the establishment of a school of cartography and navigation there. All this, however, is disputed by others, as is the tradition of his having established Chairs of Mathematics and Theology at Lisbon.[7] [Footnote 5: On this occasion he planned, but did not attempt, the seizure of Gibraltar.] [Footnote 6: Sagres, from "Sacrum Promontorium," the ordinary name of Cape St. Vincent in the later classical Geography; "à 91 Kilom. Ouest de Faro,... sur un cap, à 4,500 metres E.S.E. du Cap St. Vincent" (Viv. St. Martin). The harbour is sandy, protected from the N.W. winds. A Druid temple stood there, and the Iberians of the Roman time assembled there at night. It was a barren cape, its only natural vegetation a few junipers. O. Martins (_Filhos de D. João I_, p. 77), suggests that the name of _Sagres_ did not come into ordinary use till after the Prince's death, 1460.]
