>Christopher Columbus and the Millennial Vision of the New World, Leonard I. Sweet. The Catholic Historical Review , Jul., 1986, Vol. 72, No. 3 (Jul., 1986), pp. 369-382"Christopher Columbus is one of history's more elusive figures. In spite of recent scholarship which depicts Columbus as a figure of transition, with one foot planted firmly in the medieval world and the other in the modern world, a stubborn aura of mystery surrounds his personality and psychology. One reason why Columbus the man eludes our comprehension is that attention has focused primarily on Columbus the mariner. For example, Samuel Eliot Morison, in the prologue to his magisterial study entitled Admiral of the Ocean Sea (1942), disclaims interest in Columbus' "psychology" and "motivation" and concentrates instead on the actions of the "Discoverer" and techniques of discovery.2 A second reason why such an historical haze shrouds the figure of Columbus is that to venture into the attitudinal dimension of the admiral's life is to take a medieval journey into mysticism, dreams, visions, poetry, monasticism, crusading ideology."
>Columbus and the Recovery of Jerusalem, Abbas Hamdani. Journal of the American Oriental Society , Jan. - Mar., 1979, Vol. 99, No. 1(Jan. - Mar., 1979), pp. 39-48"The beginning of Columbus' voyages to the New World coincides with the culmination of the Spanish Reconquista and carries over the latter's crusading zeal. Columbus' Diaries reveal that his empresa de las Indias had involved a master plan of contacting the Mongol and pro-Christian Grand Khan in the East, circumventing and encircling the Islamic lands of the Middle East, opening a new trade route to the East that did not have to pass through Mamluk territories and combining the forces of Western and Eastern Christendom in an enveloping movement for the recovery of Jerusalem and its casa santa."
