I too had the wrong hardliner, but now I am fairly sure I have the correct instruction. However, the theme's source and author escape me. 17th century poet? Surely not, far too serious to be interested in the two word description.
Feeling a bit cheesed off at being marked wrong for a Philippine flag rather than a Japanese flag for 4806. I clearly had the theme and the person concerned. I assumed that the GPS information would lead me to the island and that is why I used the flag corresponding to the location.
Moreover, I think that it is now practically impossible to complete many of the puzzles if you do not have access to the Internet (unless you are some sort of polymath). However, I cannot say that Google is yielding very much on the current puzzle.
