As much as I admire my King I have to say that the poll itself is not serious and the answers are pretty much based on thoughts about today's people, Cristobal Colon show us a whole new world, half of the world speaks Spanish thanks to him and his crew regardless anything else, Ramon y Cajal discoreved the function of the neurons on the nervous system and the Cajal's cells, just to mention two ex... But we also have Charles the I, Gaudi, Severo Ochoa, El Cid, Cervantes, Pizarro, Don Pelayo, a myriad of great really historicals .
You just cannot take it seriously enough, too much royal family, people as Rocio Jurado and Lola Flores and even worse Bisbal! shoulder by shoulder with Nobel Prizes or some of Spain's greaters painters of all times, they are good or bad singers and deserve a place in other lists not on the Spaniard of the History. You can certainly not combined some tv shows with rigorous history and the 80% of the people on the list were from the XX century, is that what they call history?.
Anyways there's nothing to be worried about since we are 50 millions of citizens and only 3000 persons did vote on that poll, not representative at all and thaks God for that.
