<P0-S0> portugal spearheaded european exploration of the world and the age of discovery. <P0-S1> prince henry the navigator, son of king joão i, became the main sponsor and patron of this endeavour. <P0-S2> during this period, portugal explored the atlantic ocean, discovering several atlantic archipelagos like the azores, madeira, and cape verde, explored the african coast, colonized selected areas of africa, discovered an eastern route to india via the cape of good hope, discovered brazil, explored the indian ocean, established trading routes throughout most of southern asia, and sent the first direct european maritime trade and diplomatic missions to china and japan. <SEP> <P1-S0> Sebastian Cabot (Italian and , ; , "Gaboto" or "Cabot"; 1474 – December 1557) was an Italian explorer, likely born in the Venetian Republic. <P1-S1> He was the son of Italian explorer John Cabot (Giovanni Caboto) and his Venetian wife Mattea. <SEP> <P2-S0> Paula Santiago (born 1969 in Guadalajara) is a Mexican mixed media artist whose works have been displayed at the Monterrey Museum of Modern Art and several galleries in Europe and North America. <P2-S1> Most of her work stands out by being made with her own blood and hair. <SEP> <P3-S0> pedro álvares cabral (european portuguese: (ˈpeðɾu ˈaɫvɐr (ɨ) ʃ kɐˈβɾaɫ) or brazilian portuguese: (ˈpedɾu ˈawvaɾis kaˈbɾaw); c. 1467 or 1468 -- c. 1520) was a portuguese nobleman, military commander, navigator and explorer regarded as the european discoverer of brazil. <P3-S1> in 1500 cabral conducted the first substantial exploration of the northeast coast of south america and claimed it for portugal. <P3-S2> while details of cabral's early life remain unclear, it is known that he came from a minor noble family and received a good education. <P3-S3> he was appointed to head an expedition to india in 1500, following vasco da gama's newly - opened route around africa. <P3-S4> the undertaking had the aim of returning with valuable spices and of establishing trade relations in india -- bypassing the monopoly on the spice trade then in the hands of arab, turkish and italian merchants. <P3-S5> although the previous expedition of vasco da gama to india, on its sea route, had recorded signs of land west of the southern atlantic ocean (in 1497), cabral is regarded as the first captain who ever touched four continents, leading the first expedition that united europe, africa, america, and asia. <SEP> <P4-S0> John Cabot (Italian: Giovanni Caboto; c. 1450 -- c. 1500) was a Venetian navigator and explorer whose 1497 discovery of the coast of North America under the commission of Henry VII of England was the first European exploration of coastal North America since the Norse visits to Vinland in the eleventh century. <P4-S1> To mark the celebration of the 500th anniversary of Cabot's expedition, both the Canadian and British governments elected Cape Bonavista, Newfoundland, as representing Cabot's first landing site. <P4-S2> However, alternative locations have also been proposed. <SEP> <P5-S0> Hugo Casillas (born December 8, 1981 in Guadalajara, Jalisco) is a Mexican soccer player who currently plays defense for Anaheim Bolts of the Professional Arena Soccer League.
