Transatlantic migration refers to the movement of people across the Atlantic Ocean in order to settle on the continents of North and South America.
 It usually refers to migrations after Christopher Columbus' voyage to the Americas in 1492.
 For earlier American migration, see the article on: Models of migration to the New World.
Columbus Day is a national holiday in many countries in the Americas and elsewhere which officially celebrates the anniversary of Christopher Columbus's arrival in the Americas on October 12, 1492.
 The landing is celebrated as ""Columbus Day"" in the United States, as ""Día de la Raza"" ("Day of the Race") in many countries in Latin America, as ""Día de la Hispanidad"" and ""Fiesta Nacional"" in Spain, where it is also the religious festivity of "la Virgen del Pilar", as "Día de las Américas" (Day of the Americas) in Belize and Uruguay, as "Día del Respeto a la Diversidad Cultural" (Day of Respect for Cultural Diversity) in Argentina, and as "Giornata Nazionale di Cristoforo Colombo" or "Festa Nazionale di Cristoforo Colombo" in Italy and in the Little Italys around the world.
 These holidays have been celebrated unofficially since the late 18th century and officially in various countries since the early 20th century.
Columbus Breaking the Egg is a 1752 engraving by English artist William Hogarth.
 Issued as the subscription ticket for his treatise on art, "The Analysis of Beauty", it depicts an apocryphal tale (the "Egg of Columbus") concerning Christopher Columbus's response to detractors of his discovery of the New World.
 Hogarth uses the story as a parallel to what he considered his own discoveries in art.
Christopher Columbus's journal is a diary and logbook written by Christopher Columbus about his first voyage.
 The journal covers events from 3 August 1492, when Columbus departed from Palos de la Frontera, to 6 November of the same year.
 Columbus is known by several contemporary references to have kept a journal of the voyage as a daily record of events and as an evidence for the Catholic Monarchs.
 Upon his return to Spain in the spring of 1493 Columbus presented the journal to Isabella I of Castile.
 She had it copied, retained the original, and gave the copy to Columbus before his second voyage.
 The whereabouts of the original Spanish text has not been known since 1504.
 Copies based on an abstract from the journal have been made, most notably by Bartolomé de las Casas.
"Prayer of Columbus" is a poem written by American poet Walt Whitman.
 The poem evokes the enterprising spirit of the Christopher Columbus in a God-fearing light, who rediscovered the North American continent in 1492, leading to the colonization of the Americas by the emerging European powers.
 Although the Viking Leif Ericson has generally been credited as having discovered the North American continent roughly 500 years earlier, Columbus' rediscovery has had a more lasting impact on the colonization trends that continued until around the onset of World War I.
 Thus, Whitman's poem serves as a fitting tribute to the proper explorer.
An egg of Columbus or Columbus' egg (Italian: "uovo di Colombo" ] ) refers to a brilliant idea or discovery that seems simple or easy after the fact.
 The expression refers to an apocryphal story in which Christopher Columbus, having been told that discovering the Americas was inevitable and no great accomplishment, challenges his critics to make an egg stand on its tip.
 After his challengers give up, Columbus does it himself by tapping the egg on the table to flatten its tip.
Women have made significant contributions to Latin music, a genre which predates Italian explorer Christopher Columbus' arrival in Latin America in 1492 and the Spanish colonization of the Americas.
 The earliest musicians were Native Americans, hundreds of ethnic groups across the continent, whose lyrics "reflect conflict, beauty, pain, and loss that mark all human experience."
 Indigenous communities reserved music for women, who were given equal opportunities with men to teach, perform, sing, and dance.
 Ethnomusicologists have measured ceramic, animal-bone, and cane flutes from the Inca Empire which indicate a preference for women with a high vocal range.
 Women had equal social status, were trained, and received the same opportunities in music as men in indigenous communities until the arrival of Columbus in the late 15th century.
 European settlers brought patriarchal, machismo ideologies to the continent, replacing the idea of equality between men and women.
 They equated native music with "savagery" and European music with "civilization".
 Female musicians tended to be darker-skinned as a result of the slave trade (which increased the population of African slaves), and contemporary society denigrated music as a profession.
 Latin music became Africanized, with syncopated rhythms and call-and-response; European settlement introduced harmony and the Spanish décima song form.
The 1492 light sighting was a sighting of unknown light during the first voyage of Christopher Columbus on October 11, 1492, by some crew members of "Santa Maria", "Pinta" and possibly "Niña" shortly before the landing on Guanahani.
 The light was reported in Columbus' journal, Ferdinand Columbus' "Vita del Ammiraglio" ("The Life of the Admiral"), the proceedings of the "Pleitos colombinos" (the long lawsuit involving the heirs of Columbus) and some other sources.
In 1492, a Spanish-based transatlantic maritime expedition led by Christopher Columbus encountered the Americas, a continent which was previously unknown in Europe, leading to the colonization of the Americas.
The Columbus Monument (Catalan: "Monument a Colom" , ] ; Spanish: "Monumento a Colón "or" Mirador de Colón" ) is a 60 m tall monument to Christopher Columbus at the lower end of La Rambla, Barcelona, Catalonia, Spain.
 It was constructed for the Exposición Universal de Barcelona (1888) in honor of Columbus' first voyage to the Americas.
 The monument serves as a reminder that Christopher Columbus reported to Queen Isabella I and King Ferdinand V in Barcelona after his first trip to the new continent.
