He used the smallest possible circumference of the Earth and the greatest eastward extension of Asia he could find in all the books available to him, and then exaggerated even those. Had the Americas not been in the way, Columbus’ expeditions would have failed utterly.”” [Carl Sagan](https://sms4smile.com/quotes/author/carl-sagan/) ## About This Quote This interpretation was drafted with AI assistance.
