Whoever used the 'i' was in poor judgment particularly. The 'eta' does not sound like an i at all. It is closer to an 'e', but that still doesn't give it justice. The proper spelling of the word is therefore, 'AnatolE' with an 'eta' on the end. There are no know variations of the spelling of this word in this verse, nor are there variations at all in the text of the verse.
All manuscripts agree.
As for the definition of the word, 'AnatolE', Thayer's Lexicon gives the proper definition of 'East'. Thayer's does not have definitions for 'Anatoli' or 'Anatole'. Probably these are merely misspellings and not actually different words at all. Rest assured, however, that the word only means East. There is no difference or discrepancy.
