I find it quite bizarre that in a forum like this, no one has any clue about the origins of Columbus when it's quite clear that he's Greek.
1) Columbus' signature "Xpo-Ferens" (Christophoros), is Greek-Latin (Byzantine).
2) Columbus spelled Chios with a Greek X -- Xios.
3) Columbus marked the corner of his letters with a Greek X for Xios or Xpo-Ferens, his name.
4) Columbus named Cape Maysi in Cuba by the Greek words "Alpha and Omega."
5) Columbus never asked Italy for ships or aid or food or shelter when he needed help.
6) Columbus never spoke or read Italian.
[Lionel Cecil Jane -- "[he] could not speak or write Italian." (Select Documents Illustrating the Four Voyages of Columbus. Hakluyt Society. London, 1930.)]
7) Columbus made markings of Greek words on the margins of his favorite book, Imago Mundi, by Cardinal Pierre d'Ailly.
8) Columbus was called "Genoese" because he was from Chios, which belonged to Genoa, and he dressed in the Genoese style.
9) Columbus called himself, and signed documents, "Columbus de Terra Rubra" (Columbus of the Red Earth), because of the red earth of southern Chios where the mastic tree grows.
10) Columbus banked at St. George Bank in Genoa, along with other Genoese Chiotes, because:
a) Chios was a colony of Genoa.
b) Chios had been Genoese for almost 150 years (since 1346).
11) In Chios, over the doors of some homes in places like Pyrghi and Cimbouri, one can still see the name KOLOMVOS inscribed.
12) Columbus called himself "Colon," and wrote that he sailed with a royal kinsman who also had that name.
13) Columbus kept "a secret accurate reckoning" and two logs. The author shows that his "secret reckoning" was in Greek leagues, whereas his "official log" was in Roman leagues.
14) Ferdinand could find no sign of the Christopher Colombo family when he searched for it high and low in Genoa. These were supposedly the relatives of Christopher Columbus, but Ferdinand wrote that "I have not been able to find out how or where [they] live."
15) There is a village named Pirgi in the island of Chios where to this day many of its inhabitants carry the surname "Colombus."
This would accord with Columbus' desire to keep his identity concealed, as did many Orthodox Christian Greeks who'd migrated to Catholic Italy before and after Constantinople's fall to the Turks in 1453, and who wished to avoid persecution in their new surroundings. Columbus referred to Chios many times in his Journal, and also to the mastic gum which is cultivated only on this island in the world, and which grows in its red soil.
Signature of Columbus:
The reliance on two principle sources (though many others are also cited), written by persons who had actually seen Columbus' original Journal, are the main basis of the author's thesis. One is
Columbus' second son Ferdinand -- who had sailed with his father -- whose life work was collecting books about Columbus for his extensive library, and who wrote
The Fourth Voyage of Columbus, as well as
The Life Of The Admiral, Christopher Columbus. The other was the famous
Historia De Las Indies, by Bishop de las Casas --
who had also sailed with Columbus. These two sources, according to Durlacher-Wolper, are the most reliable because their authors had sailed with the great mariner, and knew him well. Columbus' son, Ferdinand, was known to have complained repeatedly that there were many lies and falsehoods being written and disseminated about his father. His chosen mission in life was to clear up the many misconceptions, and to let the truth be known. Bishop de las Casas, confirmed that Columbus "was of the Genoese nation," but would never utilize the Genoese language in his writings, and would refer to himself as "Columbus de Terra Rubra," ("Columbus of the Red Earth"). He also wrote that "more precise information as to his actual birthplace [was never forthcoming"], but that he claimed his ancestors "had always followed the sea." It is worthy of note that Chios Island is known for its red soil, and that Chiotes have -- since time immemorial -- been famous as seafarers and fleet owners.
Samuel Eliot Morison, the eminent historian, confirms Columbus' "ardent enthusiasm for seafaring," and wrote, in his book,
Admiral of the Ocean Sea (Little, Brown, & Co., Boston. 1942), that Columbus first took to the sea in the early 1460s, and that he made "many voyages to Chios in the Aegean," where he learned to "hand reef, and steer, to estimate distance by eye, to let go and weigh anchor properly, and all other elements of seamanship." Also, that he was a "ruddy-complexioned redhead, with blue eyes." His son Ferdinand wrote that Columbus gave himself the name "Christophoros" because "... in Greek it means one who bears Christ," and "[my father] had carried Christ over deep waters with great danger to himself ... that the Indian nations might become dwellers in the triumphant Church of Heaven."
