Hic Sunt Draconi explained (sort of)

This is probably the second real poem I ever wrote. Everything before this 
point was forced, or lacked maturity, or was fluff. This one just appeared 
one day in the fall of my sophomore year of college. The title is entirely the 
fault of Jen, Thia, and other friends of mine who were using too much Latin 
in my presence that year.

As for the meaning, it's not good enough to be subtle. It's more like a 
clue-by-four. I would, however, like to point out that I was deliberately trying 
to play on the title theme: first, that we think of ourselves as dragons, rather 
than reserving that status for the unknown of space; and second, that we 
think we know the earth, but actually, we haven't charted it all, and even if 
we did, we still wouldn't understand it. So in a way, the dragons are still 
with us. But we are not the dragons, for all our pretensions. We are toddlers 
tearing up the house before going outside to play.
