Spanish researchers have launched a new attempt to finally settle the dispute over the true origins of Christopher Columbus after various theories have claimed the explorer hailed from Portugal or Spain, rather than Italy as most scholars agree. “There is no doubt on our part [about his Italian origin], but we can provide objective data that can … close a series of existing theories,” said José Antonio Lorente, the lead scientist of the DNA study at the University of Granada. Many historians believe Columbus was born in Genoa in 1451. The university hosted a meeting of proponents of alternative theories about Columbus’s birthplace, including Spain’s Valencia, Espinosa de Henares, Galicia and Mallorca, and Portugal’s Alentejo region. “I hope with this research we will come to the conclusion that unites us in our common objective, which is to demonstrate that Columbus was a Spanish nobleman and not a Genoese sailor,” said Alfonso Sanz, an amateur history researcher and author, who said Columbus was born in Espinosa de Henares in central Spain. The results of the final stage of DNA research on tiny samples of what scientists believe are the remains of Columbus, his son Fernando and his brother Diego, will be analysed independently by laboratories in Europe and the Americas, and should be published in October. The first samples were collected in 2004-2005 and the DNA analysis will now resume after a 16-year hiatus due to technology challenges, which meant too much of the precious sample material would be wasted in exchange for too little data. “Our team agreed on an ethical approach … wait for a technological development that has now happened,” said Lorente. Columbus died in Valladolid in Spain in 1506, but wished to be buried on the island of Hispaniola, which is today shared by the Dominican Republic and Haiti. His remains were taken there in 1542, then moved to Cuba in 1795 and then to Seville in 1898.
