The Gentiles would come from the east.

"And I looked and beheld a man among the Gentiles, who was separated from the seed of my brethren by the many waters; and I beheld the Spirit of God, that it came down and wrought upon the man; and he [Christopher Columbus] went forth upon the many waters, even unto the seed of my brethren, who were in the promised land."

"And… other Gentiles… went forth… upon the many waters." "…and they did prosper and obtain the land for their inheritance; and I beheld that they were white, and exceedingly fair and beautiful, like unto my people before they were slain."      (1 Nephi 13:12-15) 600-592 BC

Ancient Prophets in the Americas, as recorded in the Book of Mormon, foretold of the coming of the Gentiles, Columbus, Hernán Cortés  etc.  
The Ancient Aztec and Maya people still retained a handed down knowledge of those prophecies as recorded in the Book of Mormon.

Bernal Castillo was with Hernando Cortes, in 1519, when he entered for the first time the Aztec kingdom of Montezuma.  While in route to the capital city of Montezuma they meet the Aztec tribe of the Caciques.  Bernal Castillo wrote what the Aztec Caciques Indians told them, recorded as follows. 

"These Caciques [Aztec Indians] also told us that they had learnt from their forefathers that one of their Idols, [Quetzalcoatl] to which they paid the greatest devotion, had told them that men would come from distant lands in the direction of the rising sun to subjugate them and govern them… and that when they made peace with us they had born in mind what their Idols had said…" "When they had finished their discourse we were all astounded and said can they possibly have spoken the truth? 
Then our Captain Cortes replied to them and said that certainly we came from the direction of the sunrise…"   (Bernal Diaz Del Castillo, The Discovery & Conquest of Mexico)

“…in a discussion that Montezuma held with the Caciques of all the territory whom he had called together, after he had made a speech without Cortes or any of us, excepting Orteguilla the page, being present, it was reported that he, [Montezuma], had told them to consider how for many years past they had known for certain, through the traditions of their ancestors, which they had noted down in their books of records, that men would come from the direction of the sunrise to rule these lands, and that the lordship and kingdom of the Mexicans would come to an end.  Now he [Montezuma], believed, from what his Gods had told him that we were these men…”  (Bernal Diaz Del Castillo, The Discovery & Conquest of Mexico, p.245)

"… in the mountains of Mani which is in the province of Tutul Xiu'…an [Maya] Indian named Ah Cambal…. announced to them publicly that they, [the Maya], would soon be subjected by a foreign race and that they would preach to them one God…"    (Landa's Relación de las cosas de Yucatán - about 1655, by the first Catholic Bishop in the Yucatan, Diego de Landa p. 43)
