"In 1713, Alexander Pope began his translation of the Iliad, a work that took him seven years to complete and that literary critic Samuel Johnson, Pope's contemporary, pronounced the greatest translation in any language."
This is a GMAT question. I am curious about the last part of the sentence. What does "the greatest translation in any language" mean? Does it mean Samuel Johnson was fluent in all languages of the world and had compared the translation of the Iliad to every other translation work that ever existed at that time?
