Azurara also requires some words of supplement as to the progress of discovery and colonisation among the Atlantic Islands in Prince Henry's lifetime.[180] And, first, in the Azores. After the first voyages of Diego de Sevill and Gonçalo Cabral, the latter (according to Cordeiro) sought unsuccessfully for an island which had been sighted by a runaway slave from the highest mountain in St. Mary; at last, corrected by the Prince's map-studies, he found the object of his search on the 8th May, 1444, and named it St. Michael, being the festival of the Apparition of the Archangel.[181] The colonisation of this (even more than of other islands in the group) was impeded by earthquakes, but was nevertheless commenced on September 29, 1445. From the number of hawks or kites[182] found in St. Michael and St. Mary, the present name now began to supersede all others[183] for the Archipelago. The island now called Terceira,[184] but originally "The Isle of Jesus Christ," was apparently discovered before A.D. 1450, either by Prince Henry's sailors, or by an expedition of Flemish mariners or colonists under one Josua van der Berge, a citizen of Bruges, who claimed the exclusive, honour of this achievement under date of 1445. Hence, in some Netherland maps and atlases, of later date, the Azores are called The Flemish Islands.[185] On the other hand, Cordeiro has printed the Infant's charter of March 2, 1450, to Jacques de Bruges,[186] his servant, giving him the Captaincy of the Isle of Jesu Christ, because the said Jacques had asked permission of the Prince to colonise this uninhabited spot. Jacques de Bruges bore all the expenses of this colonisation, and may have been specially recommended to Henry by his sister, the Duchess of Burgundy. He had married into a noble Portuguese family, and had previously rendered some services to the Infant. [Footnote 180: See Major, _Prince Henry_, pp. 238-245 (Ed. of 1868), mainly based upon Father Cordeiro's _Historia Insulana_, 1717.] [Footnote 181: Azurara (_Chronicle of Guinea_, c. lxxxiii.) says that the Regent, D. Pedro, having a special devotion to this saint, and being much interested in the re-discovery of the Azores, caused this name to be given. Prince Henry afterwards granted the Order of Christ the tithes of St. Michael, and one-half of the sugar revenues.] [Footnote 182: "Azores" in Portuguese.] [Footnote 183: "Western Islands," etc.] [Footnote 184: "The Third," apparently in order after--1. St. Mary (reckoned with the Formigas); 2. St. Michael. Its arms were the Saviour on the Cross, and it was probably sighted by the Portuguese on some festival of the Redeemer.] [Footnote 185: "De Vlaemsche Eylanden." So on Amsterdam maps of 1612 (Waghenaer); 1627 (Blaeuw's _Zeespiegel_) and others, such as the Atlas Major Blaviana, ix, Amsterdam, 1662, p. 104.]
