After his first voyage and upon arriving in Spain, Columbus penned a letter to King Ferdinand and Queen Isabella, who had financed his trip. He called the Caribbean sea the Indian sea and said that there were many islands inhabited by native Indians. One island called Juana was said to be extremely fertile with many rivers, lofty mountains and very tall trees. Another island called Hispana had many harbors and was suitable for both farming and the construction of buildings and abounded in precious metals and various kinds of animals.
He described the culture of the natives saying that they were well built but were poorly armed. He said they were innocent and could be converted to Christianity as a result of their timidity and naivety.
