[219] It retained its importance till the Prince's death, when it gradually declined; it was sacked by Drake in 1597; and ruined by earthquakes. Finally it became again as deserted as before the Infant's time. Ferdinand Denis believed that before the Lisbon earthquake of 1755 there were traces of a much earlier habitation of the Sagres Promontory, including buildings (Moorish?) at least as old as the XIth century. The headland measures only one kilometre in circuit, half a kilometre in its extreme length.
[220] Prince Henry's will refers to the Church of St. Catherine, and the Chapel of St. Mary; see the MS. Collection of Pedro Alvarez, iii; Martins, Os Filhos de D. João, p. 74. The observatory was not on Sagres Cape proper, but "un peu en avant quand on vient de l'Ouest" (V. St. Martin).
[221] Jacob or James, who, according to one tradition, came to the Infant's "Court" shortly after the disaster of Tangier, in or about 1438. To this name the Viscount de Juromenha in his notes to Rackzynski, Les Arts en Portugal, 205, adds that of Master Peter, the cartographic artist of the Infant, who illuminated his maps in colours and adorned them with legends and pictures. The existence of this Peter rests upon a document at Batalha discovered by Juromenha. See also O. Martins, Filhos de D. João I, p. 73.
[222] Wauwermans, Henri le Navigateur et l'Academie Portugaise de Sagres, gives little or no help towards the controverted question which he assumes as settled in his title. It is a general essay on the course of fifteenth-century exploration; its most useful portions are devoted to tracing the connections between geographical study in Portugal and the Netherlands.
