Does this map give any hint that Columbus knew he had found a new continent. Why or why not?

yes is the answer to your question hope this helps

maybe you should ask google for the answer for the question you're looking for

well this is going to be a long answer lol ok so the visigoths were a branch of the goths who frequently raided rome, uh the hunas attacked the guptas a lot and weakened them, uuhm of course the romans used math and science in there every day lives i mean they had a whole empire to run, and rome was split into east and west by a general named diocletian. hope this you! : )
