Question: What explorer accurately mapped the coasts of the continent where the Loire is found, as well as the region that the WINEP bundles the countries of Northwest Africa under?

<P0-S0> The human history of the Loire river valley begins with the Middle Palaeolithic period of 90–40 kya (thousand years ago), followed by modern humans (about 30 kya), succeeded by the Neolithic period (6,000 to 4,500 BC), all of the recent Stone Age in Europe. <P0-S1> Then came the Gauls, the historical tribes in the Loire during the Iron Age period 1500 to 500 BC; they used the Loire as a major riverine trading route by 600 BC, establishing trade with the Greeks on the Mediterranean coast. <P0-S2> Gallic rule ended in the valley in 56 BC when Julius Caesar conquered the adjacent provinces for Rome. <P0-S3> Christianity was introduced into this valley from the 3rd century AD, as missionaries (many later recognized as saints), converted the pagans. <P0-S4> In this period, settlers established vineyards and began producing wines. <SEP> <P1-S0> portuguese discoveries (portuguese: descobrimentos portugueses) are the numerous territories and maritime routes discovered by the portuguese as a result of their intensive maritime exploration during the 15th and 16th centuries. <P1-S1> portuguese sailors were at the vanguard of european overseas exploration, discovering and mapping the coasts of africa, canada, asia and brazil, in what became known as the age of discovery. <P1-S2> methodical expeditions started in 1419 along west africa's coast under the sponsorship of prince henry the navigator, with bartolomeu dias reaching the cape of good hope and entering the indian ocean in 1488. ten years later, in 1498, vasco da gama led the first fleet around africa to india, arriving in calicut and starting a maritime route from portugal to india. <P1-S3> portuguese explorations then proceeded to southeast asia, where they reached japan in 1542, forty - four years after their first arrival in india. <P1-S4> in 1500, the portuguese nobleman pedro álvares cabral became the first european to discover brazil. <SEP> <P2-S0> The Washington Institute for Near East Policy (WINEP) is a non-profit organization for research and advice on Middle Eastern policy. <P2-S1> It regards its target countries as the Middle East but adopts the convention of calling them the Near East to be in conformance with the practices of the State Department. <P2-S2> Its views are independent. <P2-S3> The WINEP bundles the countries of Northwest Africa together under "North Africa." <P2-S4> Details can be found in Policy Focus #65. <SEP> <P3-S0> The Piri Reis map is a world map compiled in 1513 from military intelligence by the Ottoman admiral and cartographer Piri Reis (pronounced (piɾi ɾeis)). <P3-S1> Approximately one third of the map survives; it shows the western coasts of Europe and North Africa and the coast of Brazil with reasonable accuracy. <P3-S2> Various Atlantic islands, including the Azores and Canary Islands, are depicted, as is the mythical island of Antillia and possibly Japan. <SEP> <P4-S0> gibbs point, a rock point on the antarctic peninsula, the most northern area of the continent of antarctica, was named for african american antarctic explorer, george w. gibbs, jr. on september 2, 2009. on that date, the advisory committee on antarctic names (u.s. board on geographic names) confirmed the place name in antarctica for gibbs as the first black explorer to set foot on the continent. <P4-S1> gibbs point is a rock point forming the northwest entrance to gaul cove, on the northeast of horseshoe island, marguerite bay, antarctic peninsula.
